Omega-3 fatty acids, found in fish oil, are essential polyunsaturated fats crucial for human health. They include plant-derived alpha-linolenic acid (ALA) and marine-derived eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA). Omega-3s support biochemical pathways, gene expression, and may reduce symptoms of cardiovascular disease, neurodegenerative disorders, and rheumatoid arthritis. Fish oil lowers triglycerides, alleviates depression, and eases inflammatory conditions, promoting overall health and combating aging-related diseases.
