Gary Brecka’s NAD+ Protocol for 2026: Why He Takes It and Which Form He Prefers

In this article we’ll look at what Gary Brecka takes for NAD+ and why he’s moved from precursors to direct liposomal NAD+.

NAD+ is a coenzyme that sits at the centre of cellular energy production and DNA repair. Levels decline with age, and that decline is part of why NAD+ has become a fixture of the longevity supplement conversation.

TLDR: Gary Brecka NAD+ Supplementation

• Why NAD+ matters: Cells use it to produce energy and repair DNA. Levels drop roughly 50% by age 50. Brecka says that decline shows up fast when you’re pushing hard.
• From precursors to direct NAD+: He used to take NMN and nicotinic acid. He switched when Rho found a way to put NAD+ itself inside a liposome, making oral supplementation viable without an IV.
• His daily protocol: One teaspoon of liposomal NAD+ fasted every morning, held under the tongue for ~1 minute then swallowed. He uses Rho Nutrition and Cymbiotika, both in single-serve packets he keeps in his bag for travel.
• The delivery argument: Standard oral NAD+ breaks down in the stomach before reaching cells. Liposomal encapsulation protects it through digestion. The mechanism is sound; human trial data is still limited.
• IV vs. daily oral: He prefers consistent low daily doses over a high-dose IV once a month. IV has its place for clinical situations, but daily oral is his routine choice.
• What the science supports: Animal evidence is strong. Human data is thinner and mostly based on precursors, not liposomal NAD+ directly. Blood NAD+ levels do rise with supplementation; whether that delivers the functional benefits he reports remains an open question.

Importance of NAD+ for Gary Brecka

Brecka puts it bluntly: NAD is what cells use to produce energy, it declines as we age, and because it’s present in every living cell on earth (not just in humans but in plants too), its role in cellular function is hard to overstate. (Source)

The biology backs the framing, even if the lifespan claims around NAD+ remain unsettled. NAD+ is a substrate for sirtuins and PARPs¹The Central Role of the NAD+ Molecule in the Development of Aging and the Prevention of Chronic Age-Related Diseases: Strategies for NAD+ Modulation | Poljšak et al. | 2023 | Int J Mol Sci, enzyme families involved in gene expression, stress response, and DNA repair, and a cofactor in the redox reactions that produce ATP. When NAD+ runs low, those systems run slower.

He describes it as non-negotiable for him personally: the molecule cells use to produce energy and repair themselves, one whose decline shows up fast when you’re pushing hard. (Source)

From Precursors to Direct NAD+

Brecka’s protocol has evolved. He used to take NAD precursors (NMN and nicotinic acid), which the body converts into NAD+ via the salvage pathway. He’s since moved to taking NAD+ directly in liposomal form.

Watch Gary explain his switch from precursors to liposomal NAD+ here.

He describes switching after Rho Nutrition found a way to put the NAD+ molecule itself (nicotinamide adenine dinucleotide plus) inside a liposome, a fat molecule that helps it survive first-pass metabolism. That made it possible to take orally rather than through an IV or injectable, and his morning routine is now roughly a teaspoon. (Source) 

The two often get conflated:

• NAD precursors (NMN, NR, nicotinic acid): These are smaller molecules the body uses to build NAD+. This is the approach David Sinclair is best known for. See our NMN brand comparison for the precursor side of the market.
• Direct NAD+: This is the intact coenzyme itself. The concern, as Brecka frames it, is that standard oral NAD+ is poorly absorbed; liposomal encapsulation is the workaround his products use.

Gary Brecka NAD+ Protocol

The protocol is short:

• What: Liposomal NAD+ (he uses Rho Nutrition’s Liposomal NAD+ and Cymbiotika’s Liposomal NAD+). Both ship as liposomal liquids in single-serve packets. Neither has been independently compared head-to-head, so picking between them is a question of price, taste, and which subscription a reader prefers.
• Dose: About a teaspoon once daily, as he describes it.
• When: Morning, fasted.
• How: Held sublingually for 30–60 seconds, then swallowed.
• Travel: He keeps packets in his bag and takes them across time zones; the single-serve format means no mixing or refrigeration.

Hear Gary on NAD+ for travel, focus, and recovery here.

He suggests holding it under the tongue for about a minute before swallowing, and says he notices cleaner energy, sharper focus, and better performance when he’s on it consistently. He describes it as a must-have for travel. (Source) 

He also says his focus, recovery, and energy are genuinely different when he has it on the road. (Source)

The Delivery Argument

Brecka’s position is that most NAD supplements don’t work because standard oral NAD+ breaks down in the stomach before it ever reaches cells, wasted time and money as he puts it. (Source)

The pharmacology behind this is reasonable. NAD+ is a large, charged molecule, and the gut isn’t kind to it. Liposomal delivery (wrapping the molecule in a phospholipid bilayer) is an established drug-delivery approach for improving the survival of fragile compounds through digestion.

The mechanism is plausible. The clinical-endpoint data is thinner than the marketing suggests. Whether liposomal NAD+ produces a meaningful rise in tissue NAD+ levels in humans is still being worked out. Head-to-head human trials comparing delivery forms are scarce.

The precursor-versus-direct distinction sits underneath this argument. NMN and NR are NAD precursors, smaller molecules the body converts into NAD+ through the salvage pathway. Brecka previously took that route before switching to the liposomal form. As he sees it, precursors depend on the body’s conversion machinery working efficiently, whereas liposomal NAD+ delivers the molecule itself. Whether that direct-delivery advantage shows up in tissue levels is the open question above, but in his view it’s the reason he switched.

IV vs. Daily Oral

Brecka isn’t anti-IV. He’s been clear that IV NAD+ has a place, particularly for clinical situations, but for routine use he prefers the oral route. In a conversation with Dr. Nayan Patel, he suggests that consistent low daily doses are likely more useful than a single high-dose IV drip once a month, unless something specific is going on that warrants it. (Source) 

He prefers the consistency of daily dosing over an occasional high-dose IV, which he notes comes with significant time and cost commitments.

In the same conversation, Dr. Patel notes that glutathione synthesis depends on both ATP and NAD+. The body can’t build glutathione without sufficient NAD+ in the pool. Patel’s framing suggests that topping up NAD+ also supports the body’s downstream antioxidant capacity, which is part of the biochemical rationale for pairing the two supplements.

What the Research Suggests

The preclinical case for NAD+ repletion is strong. Boosting NAD+ has been shown to extend the lifespan of diverse organisms²NAD metabolism: Implications in aging and longevity | Yaku et al. | 2018 | Ageing Res Rev. That’s the data that drives most of the longevity enthusiasm.

The human picture is thinner and more mixed. Most published human trials have used precursors (NR or NMN) rather than direct liposomal NAD+, and have measured blood NAD+ levels rather than functional endpoints like energy, recovery, or healthspan. 

NAD+ levels rise reliably with NAD precursor supplementation in placebo-controlled trials; whether that translates into the outcomes people want is still an open question. By contrast, there are currently no placebo-controlled human trials showing sustained increases in blood NAD+ levels from liposomal direct NAD+.

• Liposomal direct-NAD+ has very little human RCT data. The mechanism is reasonable, the marketing is enthusiastic, the trials are largely absent.
• The “50% by age 50” figure is a rough estimate, not a precise measurement. The precise figure varies by tissue and study, but the decline itself is real.
• Subjective benefits aren’t clinical benefits. Brecka’s reported cleaner, sharper experience is real for him; it isn’t the same as a placebo-controlled trial showing the same thing.

Roundup

Gary Brecka frames NAD+ as one of the core molecules behind cellular energy and repair, and his protocol reflects that: daily liposomal NAD+ taken sublingually on an empty stomach, with a preference for oral consistency over occasional IV drips. His switch from precursors to direct liposomal NAD+ is driven by the argument that standard oral NAD+ doesn’t survive digestion intact.

The liposomal delivery mechanism is scientifically plausible, though human trial evidence is still catching up to the marketing. If you want to see how NAD+ fits into his broader stack, the Gary Brecka supplement list covers everything he takes.
