Because the body cannot synthesize them, they must be obtained from diet or supplements. EPA and DHA are incorporated into cell membranes and act as substrates for specialized pro-resolving lipid mediators (resolvins, protectins and maresins) that help resolve inflammation. Their most consistent metabolic effect is a dose-dependent lowering of blood triglycerides. ## Its role in longevity Across large randomized trials and meta-analyses, marine omega-3s reliably reduce serum triglycerides (roughly 15% at higher doses) and modestly lower blood pressure and resting heart rate, but their effect on cardiovascular events is mixed and depends on dose, formulation and population. High-dose purified EPA (icosapent ethyl) reduced ischemic events by 25% in the REDUCE-IT trial in statin-treated patients with elevated triglycerides, whereas 1 g/day of EPA+DHA showed little overall benefit in the VITAL primary-prevention trial, high-dose EPA+DHA carboxylic acids were no better than corn oil in the STRENGTH trial, and Cochrane concluded supplements have little or no effect on all-cause or cardiovascular mortality. High doses (above 1 g/day) also raise the risk of atrial fibrillation - in a large UK Biobank cohort, regular fish-oil use was associated with a 13% higher risk of incident atrial fibrillation in people without cardiovascular disease, though possibly with benefit once disease is established - so benefits and harms must be weighed. This evidence describes the EPA/DHA compounds and their mechanisms in human health, not this specific commercial product. ## Evidence grade: Moderate evidence - **What the grade means:** Curated grade based on the human and mechanistic evidence for this compound. - **Dose used in studies:** Typical studied range 0.5-4 g/day EPA+DHA; triglyceride and blood-pressure effects are dose-dependent, clearest around 2-3 g/day. Event-reduction evidence is for prescription 4 g/day purified EPA in high-risk patients. - **What this grade does not say:** Standard over-the-counter doses did not prevent cardiovascular events or cancer in large trials (VITAL, STRENGTH) and meta-analyses, though triglyceride lowering is real. Doses above 1 g/day carry a genuine atrial-fibrillation signal - about 13% higher incident risk in a large cohort of healthy users. ## Where it comes from without a bottle Food, exercise and behaviour routes to the same pathway, each with its citation. | Natural source | How it works | Citation | | --- | --- | --- | | Fatty fish (salmon, tuna, mackerel) | Oily fish are the only foods rich in pre-formed EPA and DHA, the same long-chain omega-3s in fish-oil capsules. | Pharmacological Research 1999 [PMID 10479465](https://pubmed.ncbi.nlm.nih.gov/10479465/) | | Regular seafood / oily-fish meals | Your blood omega-3 level is set mainly by how much fish you eat, so 2+ seafood meals a week raises your EPA/DHA index much like a supplement. | American Journal of Kidney Diseases 2006 [PMID 16731302](https://pubmed.ncbi.nlm.nih.gov/16731302/) | | Flaxseed & walnuts (ALA, plant omega-3) | These give the plant omega-3 ALA, the closest non-fish precursor, but honestly the body converts only a small fraction into the EPA/DHA fish oil delivers directly. | Critical Reviews in Food Science and Nutrition 2014 [PMID 24261532](https://pubmed.ncbi.nlm.nih.gov/24261532/) | ### What those papers actually say 1. **Fatty fish (salmon, tuna, mackerel)** Pharmacological Research 1999 · [PMID 10479465](https://pubmed.ncbi.nlm.nih.gov/10479465/) · [DOI 10.1006/phrs.1999.0495](https://doi.org/10.1006/phrs.1999.0495) > DHA is present in fatty fish (salmon, tuna, mackerel) and mother's milk...
