In this post we’ll look at the supplements Rhonda takes as of September 2021. She adjusts her supplements over time, and this post is kept continually updated. If interested, view the change log here.

It’s important to note that Rhonda has no affiliation with any of the brands mentioned – instead she uses them because her research, or her colleagues research, suggest they are good.

Whilst it’s interesting to look at what Rhonda does for herself, it’s important to note that everyone is different, and it’s essential to customize supplementation to your individual medical, genetic and dietary needs.

Rhonda’s Core Supplements

Rhonda takes a lot of supplements – but her core supplements appear to be:

We’ll look at the details of those below, then later go on to discuss the rest.

Multivitamin

Rhonda continues to take the same multivitamin she has for some time – Pure Encapsulations ONE.

Having the multi ensures she gets adequate amounts of essential micronutrients, whilst minimizing the number of pills she needs to take (some multivitamins require 2 or more pills per day).

Micronutrients, a subset of which are referred to as vitamins and minerals, are regarded as essential if experiments show that humans get sick in their absence. There are over 40 (!) different essential micronutrients we need to consume, in order to stay healthy.

Rhonda’s early mentor, Bruce Ames, researched what happens when our bodies have insufficient levels of micronutrients, and found that our bodies prioritize the scarce nutrients for functions related to survival and reproduction. De-prioritizing other functions, such as those that could aid in longevity.

Rhonda interviews 92 year old Bruce Ames on micronutrients

Rhonda’s Dosage: 1 capsule/daily

N.B. For those outside the USA, where Pure Encapsulations O.N.E can be hard to obtain, see this section on comparable alternative multivitamins Rhonda has mentioned.

Vitamin D

Rhonda has always placed a high priority on the importance of adequate vitamin D levels. However, with the Covid-19 pandemic, she made an effort to emphasize it’s importance. She appeared on the Joe Rogan podcast in May 2020 (link), pointing to a link between low vitamin D levels, and increased severity of Covid-19 disease.

Of particular interest she says, is a meta-analysis in the British Medical Journal (link) that looked at 25 randomized controlled trials, and found “vitamin D supplementation was safe and it protected against acute respiratory tract infection“.

This is on top of an existing body of knowledge that suggests vitamin D plays a “major role regulating the immune system, perhaps including immune responses to viral infection”1.

Rhonda aims to keep her vitamin D levels at between 40 and 60 ng/ml, saying she generally hovers around 50 ng/ml. Note that some geographies measure in nmol/L instead – so:

  • 40 to 60 ng/ml = 100 to 150 nmol/L

For converting you can multiply ng/ml by 2.5, or use an online units calculator.

Whereas we can get adequate amounts of most micro nutrients through our diet, it’s hard to do that with vitamin D. Instead our bodies rely upon UV-B light from the sun, which we don’t always get enough of, making supplementation important.

Vitamin D is fat soluble (unlike, for instance, vitamin C), which means the body *can* store it, and your vitamin D levels *can* get too high. Therefore it’s important to use blood testing to ensure you’re staying within the healthy range. This can be done without having to get blood drawn at the doctors, using at home finger-prick blood tests such as Everlywell’s.

Rhonda’s said in multiple places recently she personally takes 5,000iu per day – and her daily multivitamin already contains 2,000IU. She last mentioned using Thorne D3, who offer 1,000iu and 5,000iu capsules. Another brand Rhonda commonly uses is Life Extension – who also offer D3 in 1,000iu and 5,000iu capsules.

Rhonda’s Dosage: 5,000IU total / daily

Magnesium

Rhonda notes that her multivitamin doesn’t contain Magnesium, therefore she adds it separately.

As of Feb 2021, she’s taking 120mg of magnesium daily, via Pure Encapsulations  – Magnesium Glycinate. 120mg is only around 30% of the RDA, as she aims to get the majority of magnesium from her diet.

However, with her mother, who she knows doesn’t eat as many greens, she encourages a higher dose.

You may also see Magnesium glycinate referred to as bisglycinate or diglycinate – they’re all the same thing!

Rhonda describes getting adequate magnesium as a “long term investment”. It’s a co-factor for over 300 enzymes in the body. Many of those enzymes have to do with energy production and energy utilisation. So it makes sense you’d want it for preventing muscle cramps and things like that. But, Rhonda says, it’s also important for repairing damage to the body, because magnesium is very important for DNA repair enzymes. That’s not something that’s going to show up acutely like a muscle cramp. DNA damage is something you’ll never know about, so making sure you get enough magnesium is extremely important for the ageing process.

Rhonda likes to emphasize that leafy green vegetables are a particularly good source of magnesium. This is because magnesium composes part of the chlorophyll molecule, the green pigment in plants that helps absorb light. So, if you see leafy green vegetables, you know you’ll be able to get some of the bound-up magnesium from it. Approximately 1/2 the US population are thought to be deficient in magnesium2

Other foods high in magnesium include avocados, almonds, oats and peanut butter (see full list here).

Rhonda’s Dosage: 120mg / daily

 

Omega-3 Fish Oil

Rhonda currently takes an omega-3 supplement called Norwegian PURE-3, which is touted as a high quality fish oil with low levels of oxidation. It comes in 2 versions; high DHA and high EPA. Rhonda currently takes 2g of the high EPA in the morning and 2g of the high DHA in the evening.

Unfortunately this particular product (Norwegian PURE-3) has had inventory issues for some time and is unavailable for order. Rhonda was asked in her June 2021 members Q&A what alternatives she would suggest…

Norwegian Pure-3 Alternative?

Rhonda’s alternative suggestion is to check the IFOS site (International Fish Oil Standards), and use their testing of fish oil purity, heavy metals contaminants and oxidation levels to find good products. She also mentioned labdoor.com do similar testing.

She then went on to specifically discuss Carlson’s Maximum Omega 2000 – saying it scored well in the IFOS tests.

Using the 2 reports available on the IFOS site (link) at the time of writing, the average total oxidation (TOTOX) for the product is 4.43 For perspective, IFOS consider a TOTOX of under 19.5 a pass. So 4.35 is significantly under their target. Comparatively, in a 2015 study (link) of retail fish oil products, out of 134 tested, the mean TOTOX value was 37 (!) (see table 3 of the study).

You can also check the test results yourself by going to its IFOS product page, and downloading the reports.

The astute reader may notice that Maximum Omega 2000 has a different ratio of omega-3s to NPure-3, as laid out in the table below. It’s most similar to to NPure-3’s EPA product.

Per 2 capsule serving Maximum Omega 2000 NPure-3 EPA NPure-3 DHA
EPA 1,250 mg 1,000 mg 400 mg
DHA 500 mg 400 mg 1,000 mg
Other Omega-3s 250 mg 300 mg 300 mg

Carlson don’t do a sister to the Max Omega 2000 product which is high in DHA – but if you want to emulate Rhonda’s approach of alternating between high EPA and high DHA, you could use the Carlson Elite DHA product, which provides 1,000mg of DHA per capsule (but with zero EPA). Based on the IFOS testing its average total oxidation value is 8.85.

Whilst supplementing omega-3s is a daily occurrence for Rhonda, she also adds salmon roe caviar a few times per week. It contains a phospholipid form of omega-3 that has additional benefits (read more below).

Vegetarian / Vegan Fish Oil Alternatives?

Rhonda personally opts to get her omega-3s from fish oil, due to its high levels of EPA & DHA per gram. However, when asked on Joe Rogan’s podcast how vegetarians can supplement EPA & DHA, she believed algae oil is the optimal source. In part, this is because fish don’t actually produce omega-3s, instead they get them from the plankton and algae in their diet – so by consuming algae you’re going direct to the source3.

In a non supplemented vegetarian/vegan diet, the primary source of omega-3 fatty acids comes from alpha linoleic acid (ALA), which is found in various plants (particularly flaxseed). However, the omega-3s EPA & DHA are also important to humans, so relying on ALA solely has a few issues:

  1. ALA is weakly converted to EPA – Research estimates between 0.2% to 6% of ALA is converted to EPA4. This aligns with a presentation by Dr Bill Harris, the omega-3 expert Rhonda interviewed, where he estimates less than 5% of ALA is converted to EPA (link).
  2. ALA barely converts to DHA – The same research paper above estimates 0.05% or less of ALA is converted to DHA5. In Dr Bill Harris’ presentation above, he similarly estimates less than 0.1% of ALA is converted to DHA.
  3. This aligns with research showing that vegetarians and vegans have lower levels of EPA & DHA compared to those who eat fish6.

The good news is that research shows algae based omega-3s will raise EPA & DHA levels in vegans, even at relatively low dose7. A study showed their omega-3 index score went from 3.1 to 4.8 after 4 months of taking 172mg DHA & 82mg of EPA per day.

Using Rhonda’s suggestion to utilize the supplementing testing results from Labdoor.com and IFOS, I’ve compiled a short list of algae based omega-3s, so you can see their cost per gram of EPA & DHAs:

Name Quantity Bottle Price EPA $/gram DHA $/gram
Nordic Naturals – Algae Omega 120 soft gels $45 $3.85 $1.92
Nature’s Way – NutraVege 30 soft gels $18.39 $4.09 $2.04
Nordic Naturals – Algae Omega 60 soft gels $25.46 $4.35 $2.18
Source Naturals – Non-Fish Omega-3s 30 soft gels $14.69 $5.44 $2.72

^ Rhonda recently interviewed Omega-3 expert Dr Bill Harris (link)

The Omega-3 Index Test

Rhonda notes in her recent Joe Rogan interview (#1701) she’s a proponent of what’s called the “omega-3 index test”. Mentioning that higher levels are associated with a lower risk of all-cause mortality8.

In essence, it measures the omega-3 fatty acids in your red blood cells, expressed as a percentage of the total fatty acids. With a score of 8% or greater being correlated with better health outcomes9.

The company that make this test, OmegaQuant, offer it as an at home “dried blood spot” test. Fortunately it doesn’t require much blood, just single drop onto a piece of card, which you then post back. OmegaQuant was founded by Bill Harris who Rhonda interviewed recently. The test comes in 3 versions:

  • Omega-3 Index Basic Test ($49) – which provides the omega-3 index score only
  • Omega-3 Index Plus Test ($74) – which provides the index score + trans fat index, omega-6 to omega-3 ratio & AA:EPA ratio (inflammation marker)
  • Omega-3 Index Complete Test ($99) – which provides everything in the Plus test, and then in addition includes a trans fat index & individual fatty acid levels

Fish Oil Rhonda Doesn’t Use Anymore

It’s probably clarifying which fish oil supplements Rhonda isn’t taking anymore – for avoidance of confusion. She no longer takes:

  • Nordic Naturals – ProOmega 2000 – she took this up until around 2017 (see last tweet mentioning). Not to be confused with the supplement she recently mentioned – Carlson Maximum Omega 2000. Since she stopped with Nordic Naturals, she has been taking NPure-3.
  • Nordic Naturals – Omega-3 Phospholipids – she took this up until around 2016 (see last tweet mentioning). However, she has since moved to consuming the salmon roe caviar mentioned above.
  • Krill Oil – prior to taking the Omega-3 phospholipids supplement by Nordic Naturals, she was taking krill oil. However, she replaced both with salmon roe caviar – and no longer takes krill oil.

Rhonda’s Additional Supplements

So far we’ve discussed Rhonda’s core supplements. In this next section we’ll look at the rest of the supplement Rhonda takes regularly:

Ubiquinol

You may already be familiar with a supplement called CoenzymeQ10. CoQ10 comes in two common forms; ubiquinone (the oxidized form) and ubiquinol (the reduced form). The version Rhonda’s taking (ubiquinol) is proposed to be more bio-available than ubiquinone10.

She describes ubiquinol as playing an important role in mitochondrial energy production.

Whilst it’s found naturally in our diets, Rhonda said in her Feb 2021 Q&A she is supplementing an additional 200mg per day

She’s specifically using Pure Encapsulations – Ubiquinol-QH 200mg – which is expensive, even for ubiquinol. Apparently it uses “Kaneka” brand ubiquinol, which is also used by Now Ubiquinol 200 mg and Jarrow Ubiquinol 200 mg – who charge notably less for it.

Rhonda’s Dosage: 200 mg / daily

 

Vitamin K2

Rhonda currently takes 50 micrograms of vitamin K2 daily (source: see her comments on this IG post + also mentioned in Feb 2021 Q&A). She takes it on the basis that it’s an “insurance policy”, in case she doesn’t get enough K1 from vegetables.

For more background on the interplay between vitamin K1 and K2, Rhonda describes it as follows…

Vitamin K is an essential micronutrient, that’s plays a crucial role in the ability to form blood clots, and to transport calcium around the body.

It comes in 2 different forms, vitamin K1 (phylloquinone) and K2 (menaquinone).

Vitamin K1 is the most abundant in a western diet, primarily found in leafy green vegetables. Vitamin K2 on the other hand is found in fermented foods, which are less common in a western diet. A source that’s particularly high in K2 are fermented soya beans, also known as “natto” in Japan.

Vitamin K1, once absorbed by the body, is prioritized for use in the liver to produce proteins essential for blood clotting. When that task is satisfied, then the level of K1 increases in the blood, and helps to transport calcium for use around the body.

Unfortunately, many people are low in vitamin K1, and therefore may have inadequate levels of K1 to support adequate calcium transport. The NHANES 2011-2012 study found only 57% of men and 37.5% of women (N = 4,306) met the “adequate intake” of K111. This could lead to increased cardiovascular risk as a result12, although more research needed.

So where does the vitamin K2 supplementation come in?

Whilst vitamin K1 is prioritized for use in the liver, vitamin K2 appears to be prioritized for use in the periphery, which will support calcium transport13.

In terms of supplementing K2 (menaquinone), there are two key forms; MK4 & MK7. MK7 has a longer half-life, but MK4 is more studied.

Rhonda said on her Feb 2021 Q&A she’s taking 50mcg of vitamin K2 (MK4 specifically) from Life Extension. However, they don’t list that product on their website or elsewhere. The closest I can find is Life Extension – Vitamin K2 MK7 45 mcg – so I will presume she means that – unless I learn otherwise.

Rhonda’s Dosage: 45 mcg / daily

Sulforaphane

Rhonda’s a big proponent of the benefits of sulforpahane and has talked about it a lot. For extensive details, see this separate post where we look at what sulforaphane is, why it’s important, and the various forms Rhonda consumes it in, including self-grown broccoli sprouts.

Currently Rhonda is consuming sulforaphane in 2 forms; prostaphane tablets and moringa powder. Note: since having her son she has less time for growing broccoli sprouts.

She takes 2 prostaphane tablets daily, and then adds Moringa in smoothies.

Prostaphane

The sulforaphane supplement Rhonda takes is called Prostaphane. Rather than containing sulforaphane glucosinolate like most sulforaphane products, it contains a free-form stabilized version of sulforaphane – which improves bioavailability.

It’s only sold in France, and so Rhonda was using a service (called moncoinsante.co.uk) to import it into the USA. At the time of writing, that website seems to be down / defunct.

Fortunately, there appears to be a new US based alternative. A company called Superhuman Health have collaborated with the French manufacturers of Prostaphane to offer a near identical product in the USA called BROQ. Prostaphane’s website mentions Broq in the header now.

BROQ contains 10mg of sulforpahane per tablet, the same as Prostaphane.

On her last Q&A Rhonda was asked about BROQ, and said whilst in theory it should be the same thing, but she still has stores of Prostaphane so hasn’t started taking yet.

Rhonda’s Dosage: 2 tablets (20mg) of Prostaphane per day, after a meal (avoid taking on an empty stomach)

Moringa Powder

Rhonda added Moringa powder to her diet after research from Jed Fahey at Johns Hopkins University. Moringa is derived from the leaves of the Drumstick Tree, which are harvested, dried and then powdered. It contains an isothiocynate with very similar properties to sulforaphane, called Moringin.

In Jed’s studies on Moringa, participants consumed it as a cold-brewed tea. This can be made by:

  • Adding moringa powder to room temperature water at ratio of 1:100 powder to water
  • Leaving to stand for at least 10 minutes, then drinking
  • The reason for avoiding hot water is because the myrocinase enzyme in moringa is sensitive to heat, and it’s crucial to preserve it

In terms of which Moringa to use, Jed’s studies used Kuli Kuli Moringa. He notes in their FAQs that excessive sunlight or heat after harvest will rapidly degrade some of the phytochemicals and vitamins of interest in the leaves – so it’s worth caution when sourcing.

As mentioned above, for more details on Rhonda’s use of sulforaphane see this separate post.

PQQ (Pyrroloquinoline Quinone)

PQQ is a compound found in plants that has been found to decrease inflammation and improve mitochondrial efficacy in humans.14. That said, it’s still relatively under studied compared to other supplements.

In a paper published in 2016, Japanese researchers found that PQQ improves cognitive function (measured using the stroop test), by increasing blood flow and oxygen metabolism to the right prefrontal cortex15

Rhonda takes 2 capsules daily of Life Extension- PQQ Caps. This comes in the disodium salt form that was used in the above study.

Rhonda’s Dosage: 2 capsules/daily

Melatonin

Melatonin is a hormone produced by our bodies to regulate the sleep-wake cycle. We produce melatonin as the sun sets and night sets in, and we reduce production as the sun rises and our body preps for wakefulness.

Rhonda suggests that melatonin can be useful as we age (particularly for those 50+), because over time our natural production decreases.

The aspect of melatonin production decreasing with age is important (see this study for more discussion). We know that good sleep is absolutely crucial to overall health, so if we can supplement melatonin and measure a noticeable positive impact on sleep, that’s a big (easy) win. This can be coupled with exercise, which also improves sleep quality (for both younger and older people).

Rhonda was previously using a low dose melatonin supplement (300mcg by Life Extension), based on this research by MIT.

She has since switched to taking a high dose (9mg), which she says helps keep her night terrors at bay. She mentioned this specifically on Joe Rogan podcast #1474.

The specific figure of 10mg likely comes from a string of research papers on sleep disruption, where ~9mg was the dose used.

Rhonda mentioned in her Feb 2021 Q&A she takes melatonin by Pure Encapsulations – possibly Pure Encapsulations – Melatonin 3mg.

Rhonda’s Dosage: 9mg / nightly

Supplements Rhonda Uses Intermittently

So far we’ve covered supplements that Rhonda has said she takes on a daily basis. In this next section we’ll cover supplements Rhonda takes intermittently.

Curcumin

Rhonda continues to take a curcumin supplement (Meriva) for its anti-inflammatory effects. Noting it also doubles as a (weak) alternative to painkillers.

She was previously taking the Thorne version  – Meriva SF – but most recently (Feb 2021) mentioned taking the Pure Encapsulations version of Meriva – CurcumaSorb.

 

Related to curcumin, Rhonda discussed the herb it’s derived from, Turmeric, in an Instagram post (link). She expressed her concern at lead chromate being added to turmeric during processing to enhance the yellow color.

Note: the easiest way to find this comment thread on her Instagram is to open the post via the Instagram mobile app – where this is the top comment. If instead you view via a web browser, then the comment isn’t at the top, and it may be hard to locate.

For more info on turmeric and lead chromate, see these studies:

  • Ground Turmeric as a Source of Lead Exposure in the United States – link
  • Lead chromate pigments added to turmeric threaten public health across Bangladesh – link

Rhonda continues to utilize turmeric in its organic form (which doesn’t have lead chromate added) – both as juices and in smoothies. It has a host of potential benefits, including:

  • A randomized controlled trial showed that a bioavailable form of curcumin improved memory in older people with mild memory complaints. The curcumin group had a 28% improvement in their memory/attention abilities and fewer amyloid plaques and tau tangles in the brain, compared to the placebo. The latter (amyloid plaques and tau tangles) affect optimal brain function, and are hallmarks of Alzheimer’s disease.
  • Additionally a double-blind, randomized and placebo-controlled trial showed antidepressive effects in patients with major depression16

The bioavailability of curcumin can be increased with the addition of fat and a component of black pepper called piperine. For fat sources, Rhonda adds avocado to her smoothies that have turmeric (see her Instagram post on this).

Cocoa Extract

Rhonda first mentioned taking a cocoa flavanol supplement in her December 2019 supporters crowdcast, and then more recently discussed it in her Feb 2021 Q&A.

She says she’s taking 2 capsules of CococaVia daily, specifically in the morning, because it contains a small amount of caffeine.

Rhonda cites 3 potential benefits of cocoa flavanols:

  • Enhanced circulation
  • Improved cognitive function
  • Improvements to skin (decreased wrinkles and increased skin elasticity)

See the studies Rhonda mentions in regard to enhanced circulation:

  • Dark chocolate (85% cocoa), but not milk chocolate (35% cocoa), improved walking ability in elderly patients with peripheral artery disease.17
  • Increased endurance performance in young male cyclists who consumed dark chocolate – showing a performance increase of 17% vs consuming white chocolate18
  • Cocoa consumption decreased blood pressure in healthy individuals, in a dose dependent manner 19

Then studies in regards to enhanced cognition:

  • Increased cognition in young adults, measured via a cognitively demanding test20
  • Protection from cognitive decline in the elderly21

Then lastly, a Korean study showed 320mg of cocoa daily reduced wrinkles and increased skin elasticity (measured after 24 weeks)22.

Of course, it’s worth noting that the amount of cocoa in regular chocolate is low – so you want to be consuming high cacao content products to receive these benefits. The studies above specifically reference the cocoa flavanol content as a quantitative marker, and CocoaVia contains 450mg of cocoa flavanols per serving.

In an Instagram post (link) Rhonda mentions studies have shown that many cocoa products have high levels of cadmium and lead23. That’s a blow for dark chocolate fans (myself included) who hadn’t considered heavy metal consumption might be a risk. She goes on to say that in a Consumer Lab report, the CocoaVia brand was shown to have almost undetectable levels of cadmium and lead – making it a safe option, and a key reason she opted for it.

It’s perhaps worth noting that CocoaVia lunched a new product called Memory+ (in a blue bottle). It’s a higher dose product (750mg vs 450mg), which is based off clinical studies2425 that showed this dose improves word recall and led to faster spatial memory versus the placebo. Interestingly, at price per gram of flavanols, it also works out cheaper than the original version ($2.22/gram vs $3.33/gram). This version just came out, so it’s not the one Rhonda previously mentioned taking, but it is by the same brand.

Rhonda’s Dosage: 4 capsules per day, in the morning, intermittently

For Immune Function

Back in Rhonda’s March 2020 Q&A for crowd sponsors she switched her whole supplement routine up to focus on immune support for Covid. The virus was still new then, and she was “throwing the kitchen sink” at it with supplements.

A year has passed, and we understand the threat a lot better. Of the supplements she was taking with immune function in mind, she continues taking 2 of them now; high-dose vitamin C and Quercetin – which we look more at below.

But first, if you’re curious what her full list was, expand the box below.

The full list of Rhonda’s early 2020 supplements for immune support, with Covid in mind:

  • Vitamin C – 1-2 grams, 4x per day
  • Quercetin– 250 mg/daily
  • Zinc – 15mg/daily (on top of the 25mg in her multivitamin)
  • N-acetyl L-cysteine (NAC) – 1200 mg/daily
  • Liposomal Glutathione – 500 mg/daily
  • Sulforaphane – via Prostaphane and Moringa

Given that she’s still taking:

  • Vitamin C – 0.5-1 g 1x in evening
  • Quercetin – 250 mg/daily
  • Zinc – 25 mg daily (via her multivitamin)
  • Sulforaphane – via Prostaphane and Moringa

She’s only really dropped the NAC and Glutathione, and then reduced her daily doses of Zinc and Vitamin C.

Vitamin C

With immune function in mind, Rhonda did a deep dive into the literature on vitamin C – producing a large Vitamin-C topic page on her site. Her research began with some skepticism, but after pouring through the data, she became convinced it’s benefits are appreciable. Rhonda spoke at length about vitamin C supplementation at 59mins 10secs of her March 7 Q&A for crowd sponsors.

In terms of which form to take, Rhonda was taking it as regular ascorbic acid. She hasn’t seen any convincing evidence that it needs to be taken alongside flavonoids or in a liposomal form. Not to mention the liposomal form is significantly more expensive.

Rhonda hasn’t specified which brand of vitamin C she favors, but typically she opts for brands like Thorne – Ascorbic Acid or Pure Encapsulations – Ascorbic Acid. Both have 1g (1,000mg) per capsule.

Rhonda’s Dosage: 0.5-1 gram intermittently in evenings

Quercetin

Quercetin is a naturally occurring plant polyphenol, found in small quantities in foods such as capers, cilantro, kale and more (see list).

Rhonda is particularly interested in quercetin for the research suggesting it may act as a “zinc ionophore” – helping to get zinc into cells, which can be otherwise hard. This relates to the idea that zinc may inhibit viral replication2627.

“Ionophores”, by the way, are substances which can transport particular ions across a lipid membrane in a cell.

Rhonda currently supplements 250 mg per dose. She didn’t mention which specific brand she is using, but typically she opts for brands like Pure Encapsulations  – Quercetin or Thorne Research – Quercetin.

Rhonda’s Dosage: 250 mg intermittently

On the subject of quercetin, Rhonda has also taken up drinking Buckwheat Tea, which contains quercetin in small amounts. In addition to being a zinc ionophore, quercetin also has senolytic properties, which Rhonda talks about more on Instagram here (senolytics are compounds that can remove senescent cells). If you’re new to Buckwheat tea, and would like to try it, you’d be looking for a roasted blend (rather than raw) which brings out more flavor.

Further supplements:

Probiotics

Rhonda is keenly aware of the importance of a healthy gut microbiome. Typically she takes Visbiome probiotics every few weeks, to top up her healthy gut bacteria.

For example, probiotics can help regulate the innate and adaptive immune responses by modulating the functions of dendritic cells, macrophages, and T and B lymphocytes2829.

Visbiome comes in sachet and pill form. Rhonda opts for the sachets which contain 4x as many live bacteria.

Before switching over to Visbiome, Rhonda was taking VSL #3 probiotic, which had been the subject of over 25 publishes studies, showing efficacy in IBS, IBD, colitis and c. diff. However, it turns out the new formulation of VSL #3 differs significantly from the old one30, and thus should be treated with caution at minimum, and at maximum, avoided. I mention this section because for some people Visbiome is hard to get hold of, and up until now, it was thought VSL #3 was a satisfactory alternative. Below summarizes the details:

VSL #3 was originally created by Professor Claudio De Simone, and produced by VSL Inc. All the clinical studies before 2016 were performed on the “original formula” of VSL#3. However, when Di Simone parted ways with VSL Inc. in 2016, manufacturing was switched from USA to Italy and the formulation was changed. Between 2016 and 2019, VSL Inc. claimed that the beneficial effects of the formula remained the same. However in a federal lawsuit that concluded in 2019, VSL Inc. were found liable for false advertising related to the composition and clinical history of the new VSL #3 formula. This was in part backed up by a study31 performed by De Simone, showing that the new VSL#3 formula was materially different to the old one.

For those looking for the benefits of the original VSL# 3 formula, this continues to exist under the Visbiome brand.

Dosage: 1 sachet/every 1-2 weeks

Omega-3 Phospholipids

Rhonda currently gets her omega-3 phospholipids from wild salmon roe caviar. She bulk buys her caviar from Vital Choice, who offer it in 2.2lbs packages that can be frozen, and then defrosted one quarter at a time. Consuming this in addition to her regular omega-3 supplementation.

She opts for the salmon roe rather than supplements, as it’s a potent, fresh source of phospholipids (~438 mg of EPA and ~514 mg of DHA per ounce). Prior to this she was taking a herring roe extract made by Nordic Naturals, and before that, Krill oil. See this and this Instagram post for more on Rhonda discussing salmon roe.

Omega-3 Phospholipids, Alzheimer’s & APOE4

Rhonda’s keen interest in omega-3 phospholipids stems from having 1 ApoE4 allele in her DNA.

ApoE4 increases Alzheimer’s risk between 2-3x if you’ve 1 allele and 15x with 2 allele’s. It’s estimated that around 25% of the population have at least 1 ApoE4 allele.

Part of the reason for the increase in Alzheimer’s risk with APOE4 is that it impairs regular DHA transport into the brain.

In 2018 Rhonda published an open access paper on a possible mechanism for getting DHA into the brain, which bypasses the impaired route.

^ Rhonda displaying her ApoE4 paper

Rhonda’s paper proposes that consuming DHA in phospholipid form gets around impaired DHA transport. The reason for this is that phospholipid DHA gets converted to DHA-lysoPC, by a specialized transporter called MFSD2A32. This transport system appears to continue to work even when regular DHA transport is impaired.

Providing DHA to the brain again, in the form of DHA-lysoPC, may reduce Alzheimer’s disease risk.

According to Rhonda, omega-3 phospholipids are found in fish, and in greatest concentration in fish roe (fish eggs).

You can test yourself for ApoE4 by using a test like 23andMe (their cheaper ancestry test is sufficient) – and then exporting the raw data they provide into Rhonda’s genetic report or to Promethease. 23andMe’s more expensive health package should include ApeE4 testing as standard.

Collagen Powder

In Rhonda’s June 2021 Q&A she mentions using collagen powder daily to benefit her skin, hair and joints. She consumes it by adding it to her smoothies, coffee and sometimes tea.

Her original interest was inspired by a study that showed peptides in collagen actually make it intact to cartilage, which suggests its beneficial for joint health (source).

Additionally, Rhonda’s interest was piqued by a study showing that in 26 healthy females who displayed visible signs of natural and photoaging in the face, daily supplementation with 1 gram of collagen powder for 12 weeks led to a 76% reduction of skin dryness/scaling and a 13% decrease in global lines and wrinkles. Additionally, an 18% increase in the content of haemoglobin was found in the skin dermis suggesting improved microcirculation (study source).

See Rhonda’s Instagram post on collagen for more info. In her June Q&A she mentions using both Great Lakes Collagen and Vital Proteins Collagen.


Nootropics

Nootropics are products aimed at improving cognitive function, and in Rhonda’s June 2021 members Q&A she updated us on her preferred nootropic, which she consumes in the form of a drink.

First though, she caveats by saying her foundations for maximizing cognitive function are:

  • Good quality sleep – see this post for how she optimizes her sleep
  • Regular cardio exercise – such as running/spin bike
  • Intermittent fasting – such that she stays in ketosis throughout the morning while she works
  • Consuming sulforaphane – which raises glutathione in the brain, lowering oxidative stress + inflammation
  • High dose fish oil – of which the DHA is key for brain function

Now let’s look Rhonda’s nootropic drink. It contains:

  • Lion’s Mane Mushroom – she preferences Laird’s Performance Mushrooms blend
  • Cocoavia Cocoa powder (1 sachet)
  • A 50/50 split between coconut powder and MCT powder
  • Stevia – to make it taste nice
  • Cinnamon powder
  • Water

She says it’s like dynamite for the brain, and she feels “on fire” with it” 🔥

In the mornings she limits herself to just 1 coffee, to which she sometimes adds the Laird’s mushroom blend mentioned above. Then, if she wants an extra boost, she will make the nootropic drink. She adds a couple of important caveats:

  1. The cocoa powder naturally contains a small amount of caffeine, so she avoids drinking the mix too late in the day, as that can impact sleep quality.
  2. She avoids using a dairy creamer, because dairy contains a protein that can inhibit the flavonoids in the cocoa.

It’s worth mentioning that this particular blend of mushrooms isn’t available everywhere. An alternative are pure Lion’s Mane products, such as:

In terms of an estimate on dosage for the Lion’s Mane, Rhonda cites a study (source) that showed significant improvements in cognitive function after 8 weeks of 3g per day vs placebo – for 50-80 year olds with existing cognitive impairment.

Beet Powder

Whilst Rhonda doesn’t supplement beet powder herself, she did use it successfully to lower her mother and mother-in-law’s blood pressure, and thus avoid them getting on blood pressure medication (see Rhonda’s Instagram post on this topic for more info).

Additionally, she talks about the many studies that have shown positive effects of beets on blood pressure, endothelial function, heart health, improved blood flow to the brain, and endurance performance. Beets are apparently one of the highest sources of nitrate (which then gets converted into nitric oxide) and is thought to increase blood flow to the brain. Beets are also high in vitamin C, which prevents the conversion of nitrates into nitrosamines (those carcinogens that are formed from the nitrites which are used as preservatives).

The Activz Organic Beet Powder Rhonda used for her family has the equivalent of 1 cup of beet juice per 9 gram scoop (~3 teaspoons). Her Mum was taking 9g per day for 2 weeks before she got her blood pressure re-tested.

Unfortunately Activz Organic Beet Powder appears to be out of stock everywhere, so have listed some potential alternatives below. Unfortunately was unable to find an option that’s both made in USA and organic. The options where the beets are grown in India is both organic, and well priced, I just don’t know much about the rigor of India’s organic produce.

Antler Farms Beet Powder$15.00Non GMOOrganicNew Zealand

Vitamin B Complex

Rhonda doesn’t take B vitamins in addition to the B vitamins in her multivitamin. In part, because Rhonda does not have 677CT or 677TT MTHFR mutations that indicate poor vitamin B absorption.

However, for those like her mum who are T-homozygous the MTHFR gene (SNP = rs1801133), which leads to poor uptake of folate, they may benefit from up to 800 micrograms supplementation of 5 methylfolate. If you were to take O.N.E multivitamin, which contains 400mcg, you would need an additional source such as Swansons B-Complex, which has 400 micrograms per capsule. Other B vitamins that may be of benefit for this issue are B6 and B12.

Swanson’s B-Complex is the B vitamin Rhonda took previously (source), before she cut back on B vitamins, and its particularly useful because it contains methylated versions of the B vitamins. Which is an exception, rather than the rule for vitamin B complex supplements.

To understand your own bodies ability to absorb vitamin B, you need to sequence your SNPs. The cheapest way to do that is to use 23andMe’s $99 service (you don’t need their $199 service) or Ancestry’s $99 service. Once that’s done you can export your SNP data to services like Promethease ($12) and/or Rhonda’s genetics tool ($25).

Not Currently Taking

This section covers supplements that Rhonda has previously taken but isn’t currently. I could just strike them from the list, but I think for some this list (and the rationales) may be of interest.

Nicotinamide Riboside

Prior to having her son, Rhonda was experimenting with a Nicotinamide Riboside supplement by Thorne. However whilst pregnant, Rhonda stopped taking any non-essential supplements (including Nicotinamide Riboside) that could pose even the slightest risk to her child.

The nicotinamide riboside product she was taking before was called Thorne NiaCel (now discontinued) – which contained Nicotinamide Riboside Chloride made by Chromadex. Chromadex also produce Nicotinamide Riboside under their own brand; called Tru Niagen.

As of yet, Rhonda hasn’t come back to taking Nicotinamide Riboside, and has said she is waiting for more human research to be completed.

Resveratrol

Rhonda has had David Sinclair on the podcast discussing the positive effects of Resveratrol. Since that podcast, Rhonda has posted a literary review of Resveratrol on her site.

In her Dec 2019 Q&A discussion, she discussed Resveratrol, saying that she doesn’t take it currently, but is considering taking it.

She says her interest in resveratrol stems mainly from preliminary clinical trials showing positive benefits in cognition for older and cognitively impaired adults, including:

  • A study, 200mg/daily resveratrol supplementation improved healthy 50-75 year olds memory recall33.
  • In another study, patients with alzheimer’s disease who took resveratrol saw improvements in cognition, and decreases in biomarkers of Alzheimer’s disease and inflammation34.

Her current reservation is around a study that showed 250mg/day of resveratrol blunted the positive effects of exercise35. However, another study using 500mg showed synergistic effects in combination with exercise36. Rhonda’s current hypothesis for why is that at lower doses resveratrol may act as a mild antioxidant, which then blunts the positive effects of exercise (similar to high dose Vitamin E).

When asked what type of resveratrol she would take, she said a micronized powder form, and that a company called RevGenetics make that (noting again that she has no connection with them or any other supplement company).

For more on David Sinclair and the supplements he takes, including Resveratrol and NMN, see this separate post.

Metformin

Metformin has been studied in humans since the 1950’s, and is most commonly taken to battle type 2 diabetes. In recent years its become popular amongst biohackers looking to extend their healthspan + lifespan. As this novel, off-label use has become more popular, its invited further research into whether this approach makes sense.

In a podcast with Kevin Rose (Jan 2020 – link), Rhonda discussed the use of metformin for longevity.

She notes that exercise is better at preventing type 2 diabetes than metformin, citing a randomized controlled trial involving 3,200 people37. She also questions the value of metformin in healthy individuals who exercise. This is because the health benefits of exercise are vast and well documented, and it appears that metformin inhibits a number of these. Namely:

  • Reduction in gaining lean muscle mass whilst on an exercise program, compared to placebo38.
  • Inhibition of mitochondrial adaptations and improvements in cardiorespiratory fitness by 50 percent and diminished whole-body insulin sensitivity after aerobic exercise39.

So when it comes to healthy individuals who exercise, she doesn’t see any synergy with the use of metformin for improving healthspan and lifespan. However, for people who don’t exercise, then the use of metformin may warrant further inspection. See Rhonda’s research section on metformin for more info.

Note that if you’re interested in taking the prescription drug metformin for off-label use, you should consult with a doctor on the subject. The above does not constitute medical advice in any shape or form.

Multivitamin Alternatives

For those outside mainland USA, Rhonda’s multivitamin; Pure Encapsulations O.N.E can sometimes be difficult to obtain. A good alternative (Rhonda used one of Thorne’s multivitamins during pregnancy) is:

Other comparable options include:

All 3 options contain methylated folate, rather than folic acid, which is important for poor methylators.

This ends the main list of supplements.

Below we’ll look at supplements Rhonda used during her pregnancy (a section which, of course, won’t be applicable to all). You can instead skip to the next section – Rhonda’s Method for Choosing Supplement Brands.

Rhonda’s Pregnancy & Breastfeeding Supplement Regimen

This section just includes a summary of the supplements Rhonda used whilst pregnant and breastfeeding. For the full post on the subject, see here.

First & Second Trimesters

Rhonda’s regular supplement regime contained products such as Lion’s Mane mushrooms and Nicotinamide Riboside that haven’t been tested in pregnant women. Therefore to maintain absolute safety, Rhonda removed all these supplements from her diet whilst pregnant, and only used the following:

Third Trimester

  • Rhonda continued using the products above, and added Visbiome probiotics – 1 sachet/day (Visbiome was created by the same person as VSL#3, has a similar formulation, and typically costs less). She didn’t take probiotics first or second trimester.
  • Her third trimester blood test results came back showing iron deficiency, so she added an extra iron supplement: Thorne Research – Iron Bisglycinate. This won’t be necessary unless your blood test results indicate low levels. The prenatal multivitamin already contains 45mg of iron bisglycinate.
  • Rhonda increased her Wild Alaskan Salmon Roe intake to daily (source) – on the basis that in the last 13 weeks of pregnancy, the babies brain triples in weight, and the cerebellum (involved in motor control) increases surface area by 30x.
    So by consuming the salmon roe, she provides her baby with a good source of phospholipid DHA (absorbed 10x better in the developing brain than regular DHA), and DHA is one of the major components of the brain. Rhonda buys her salmon roe in bulk from Vital Choice.

Breastfeeding Supplement Regimen

[1] Rhonda added back sulforaphane whilst breastfeeding (after taking a break whilst pregnant) but opted for Prostaphane capsules, to avoid any risk of contaminated broccoli sprouts, and to free up time for baby duties. I’ve talked about Prostaphane and sulforaphane more in this post. Prostaphane is actually only sold in France, so has to be exported. The closest equivalent available in USA is Avmacol.

The source for details on Rhonda’s breastfeeding supplement regime is 1hr 38mins into her October crowdcast video for Patreon supporters.

Toddler Supplements – For a list of the supplements Rhonda is giving to her growing toddler, see this separate post.

Prenatal Multivitamin

(It’s worth noting with the above study, that it was performed on people in rural China. It’s possible they were already mildly deficient in micronutrients, thus the multivitamin supplement had a noticeable impact on their children’s IQ. That being said, we know that even in developed countries like the USA, segments of the population are mildly deficient in essential micronutrients, so the study still holds value. What has not been proven is that a multivitamin could improve IQ where no deficiency exists).

Research has shown that pregnant women need more of certain nutrients than they would otherwise. Rhonda opted to use a multivitamin by Thorne, called Basic Prenatal. This has a number of key benefits:

  • Supplementation of folic acid reduces the risk of having a child born with brain of spinal cord birth defect40. Basic Prenatal uses the methylated form of folate (5-MTHF), which is optimal even for those with an MTHFR mutation that makes them less efficient at utilizing folic acid. Actually, for those women with the aforementioned MTHFR mutation, neural tube defects are a bigger risk than normal41
  • As well as using an optimal version of folic acid, Basic Prenatal also uses a well absorbed version of iron, iron bisglycinate, which meets a pregnant woman’s need for increased iron, whilst being easy on the stomach and non-constipating.
  • It contains several of Basic Prenatal’s ingredients (including vitamin C, vitamin B6, and vitamin K) have been demonstrated to benefit morning sickness.
  • Lastly, it doesn’t contain any additives like stearates, colorants or preservatives – unlike some mainstream prenatal supplements.

For more information on approaches Rhonda took to her pregnancy and breastfeeding, see this detailed post I’ve written up on the subject.

Rhonda’s Method for Choosing Supplement Brands

The supplement industry, surprisingly, is largely unregulated. Especially when compared to the stringent regulations that are imposed on the pharmaceutical industry. This amplifies the importance of choosing a supplement that you can rely upon. In a Tim Ferriss interview Rhonda recommended that you check if the supplement brand you’re looking to buy is certified by the NSF (National Sanitary Foundation). Their role is to independently test and certify supplements, to ensure they do not contain undeclared ingredients or contaminants.

As a guideline, below is the list of brands that Rhonda often uses (either currently, or in the past):

Then separately, Rhonda has discussed using labdoor.com in order to check supplements for contaminants. For example, when she was choosing a cocoa supplement, she went to labdoor to see which were low in heavy metals.

Thanks for this post is is fantastic! I am a little suprised actually shocked Rhonda takes melatonin! If she has such a healthy lifestyle ( which she does) and taking all those supplements, why does she need it? Did she mention why she has that need. I know you mentioned she said night terrors ( but even that show she has something out of balance if she has that all the time. I trust her she is fantastic but I am truly curious. Have you heard her talking about why she needs melatonin? Again with the way she lives her… Read more »

John, thanks so much for the link! It explains a lot to me that in the beginning she kinda was talking about it t in an embarrassed manner (almost like a confessing)manner. Which tells me she wishes she is not on it. And its amazing she can resolve such bad night terrors with it. Also, stress is such an interesting thing (she said she has more terrors when she is stressed out) I know its part of being a human but you can be one of the smartest people on earth, exercises use the best supplements eat the best food… Read more »

I always thought that you need a lot of extra vitamin e when supplementing fish oil, but she doesn’t take any extra. Don’t you need some kind of protection that those high doses of EPA and DHA won’t oxidize in body?

Hey John,

Wanted to start by mentioning that youre doing Gods work by summarizing and outlining Rhondas work and making it even more accessible! Thank you!
So I recently started buying avmacol for sulphuraphane supplements and wanted to know if you knew what website/service Rhonda utilized to get Phostaphane delivered to her in the US. Also, are you aware what dose per serving was delivered in phostaphane? Because I wanted to match it with my avmocol supplements where serving size is 475mg Propietary Sulpherophane Glucosinate & Myrosinase blend per day.

Hi John,
Is there is a general rule to choose powder filled capsules or gel cap supplements, as opposed to hard-pressed tablets? Just looking at Rhonda’s daily supplements, it appears that she doesn’t take anything in tablet form, which I assumed was for a better rate of absorption. However, one of the alternative multivitamins listed here, Opti-Men, comes in a tablet form.

Hi John! I buy my sprouts from sproutpeople.org and although there may be better sources out there, they’re high quality and I go through a lot, so they’re affordable. Thanks for your comment, I checked their site and they sell Green Sprouting Calabrese which is true broccoli, they also ship out of country. Good luck! I had a mini panic attack for a minute there as I just bought a bunch of sprouting seeds, and I didn’t want to discard. 🙂
