What it is
Two specific fats found in oily fish (salmon, sardines, mackerel) and algae. Your body needs them but can't make them well from plant sources.
Why people take it
Meta-analyses of tens of thousands of participants show cardiovascular event reductions. The recent VITAL and REDUCE-IT trials clarified who benefits (people with high triglycerides, existing heart risk, or low omega-3 intake). Brain, eye, and inflammation benefits also well-documented.
Our verdict
If you can only pick one supplement for longevity, omega-3 is a strong candidate, especially if you don't eat fatty fish 2× a week.
Structure & class
EPA (eicosapentaenoic acid, 20:5 n-3) and DHA (docosahexaenoic acid, 22:6 n-3). Long-chain PUFAs.
Mechanism & clinical data
REDUCE-IT (2019) demonstrated 25% MACE reduction at 4 g EPA (icosapent ethyl) in high-risk patients. Meta-analyses confirm triglyceride and blood-pressure lowering. Omega-3 index target: 8 to 12%.
Pharmacokinetics
Days (incorporation into cell membranes).
Dose & forms
What to watch out for
Ethyl ester (cheaper) absorbs worse than triglyceride form unless taken with fatty meal. Check third-party oxidation testing (TOTOX <10).

EU Court sharpens the bar for botanical health claimsA Court of Justice of the European Union ruling in april 2025 further tightened the requirements for how botanical ingredients (herbs, plant extracts) can be marketed with health claims in the EU, effectively removing much of the flexibility of the on-hold list.
-
EU report identifies 117 supplement substances as potential health risksThe HoA Working Group on Food Supplements (26 European countries) published its first report evaluating 117 substances used in food supplements. Of these, 65 were assessed as likely novel foods, 6 were already regulated, 34 had insufficient data, and 12 were prioritized for Article 8 restriction under Regulation (EC) No 1925/2006. The 12 priority substances include ashwagandha, curcumin, melatonin, piperine, St. John's wort, coumarin, p-synephrine, maca, holy basil, Melaleuca, black cohosh, and L-tryptophan. The report drew on 1,500 RASFF alerts reviewed between 2017 and mid-2022.

HoA 2024 (BVL/NVWA, EU)26-country EU working group prioritized curcumin for Article 8 restriction. Flagged for possible carcinogenic, mutagenic, or reprotoxic properties at supplement doses exceeding normal dietary intake.

Barbaresko et al. 2023 (cognitive review)Review of RCTs found that 3.36 g/day EPA+DHA slowed cognitive aging by 2.5 years in cognitively healthy people with coronary artery disease, with more mixed results in general older populations.
-
Khan et al. 2021 (38 RCTs metaanalys)A metaanalys of 38 RCTs (149,051 participants) found omega-3 fatty acids reduced cardiovascular mortality, non-fatal MI, and major adverse cardiovascular events, with greater benefit from EPA monotherapy than EPA+DHA.
-
Bernasconi et al. 2021 (Mayo Clin Proc)Across 40 RCTs (135,267 participants), EPA/DHA supplementation reduced risk of myocardial infarction and coronary heart disease events in a dose-dependent manner.
-
FDA adds qualified health claims for EPA/DHA and blood pressureThe FDA announced it would not object to qualified health claims stating that consuming EPA and DHA combined may reduce blood pressure and the risk of hypertension, a risk factor for coronary heart disease. The agency found some credible evidence but concluded it was inconsistent and inconclusive. Produkter bearing the claim must contain at least 0.8 g EPA+DHA per portion. The FDA also raised the safe upper intake limit from 3 g/day to 5 g/day for supplements using the claim.
-
REDUCE-IT 2019 (NEJM)In 8,179 statin-treated patients with elevated triglycerides, icosapent ethyl (EPA) reduced major cardiovascular events by 25% versus placebo over a median 4.9 years.
-
VITAL Trial 2019 (N=25,871)In 25,871 U.S. adults followed 5.3 years, daily marine omega-3 (1g) supplementation did not significantly reduce major cardiovascular events or total cancer incidence in the general population.
-
EU authorises health claims for DHA and EPARegulation (EU) 432/2012 established a list of authorised health claims for DHA and EPA, including contributions to normal brain function (250 mg/day DHA), normal vision (250 mg/day DHA), normal heart function (250 mg/day EPA+DHA), maintenance of normal blood triglyceride levels (2 g/day EPA+DHA), and maintenance of normal blood pressure (3 g/day EPA+DHA). Produkter must contain at least 40 mg EPA+DHA per 100 g and per 100 kcal to bear the source claim.
-
EU Health Claims Regulation adoptedRegulation (EC) No 1924/2006 laid down harmonised rules for nutrition and health claims made on foods, including supplements. Only claims listed in the EU Register of authorised claims can be used. Rejected botanical claims are held in a separate on-hold list.
-
FDA allows first qualified health claim for EPA/DHA omega-3 and heart diseaseThe FDA permitted a qualified health claim stating that supportive but not conclusive research shows that consumption of EPA and DHA omega-3 fatty acids may reduce the risk of coronary heart disease. This was the first time the FDA allowed a heart-related claim for omega-3 supplements, though with qualifying language acknowledging the evidence was not definitive.
-
EU introduces the Novel Food RegulationRegulation (EC) No 258/97 required any food or food ingredient without a history of consumption in the EU before 15 maj 1997 to be authorised before being placed on the market. This is the framework that captures NMN, spermidine as a supplement ingredient, urolithin A, and many other longevity actives.
Reported adverse events
Consumer reports submitted to an official government adverse-event database. These reports mention this ingredient but do not prove it caused the reaction. Report volume reflects market penetration as much as inherent risk.
Retrieved from the FDA Adverse Event Reporting System (CAERS) via the openFDA API. Verified 2026-08-06. Reports are voluntary consumer submissions and mandatory serious-event filings. They establish surveillance, not causality.
Omega-3 fish oil (EPA and DHA) lowers triglycerides and modestly cuts cardiovascular events, with effects varying sharply by formulation and dose.
Verified 2026-07-19. We update this section as new peer-reviewed trials land.
Best-supported claim
The strongest human evidence is for cardiovascular risk reduction, but it depends heavily on formulation. REDUCE-IT, using 4 g/day of purified EPA (icosapent ethyl), cut the composite cardiovascular endpoint by 25% (https://www.sciencedirect.com/science/article/abs/pii/S0025619619304112). A 2021 metaanalys of 13 RCTs and 127,477 participants found marine omega-3 significantly reduced myocardial infarction, coronary heart disease death, total CHD, CVD death, and total CVD, with effects strengthened once REDUCE-IT was included (https://www.ahajournals.org/doi/10.1161/JAHA.119.013543). A separate 2021 metaanalys of 38 RCTs and 149,051 participants found EPA-only therapy produced a larger cardiovascular mortality reduction (RR 0.82) than EPA plus DHA combinations (RR 0.94), suggesting EPA alone may be the more potent cardioprotective form (https://pmc.ncbi.nlm.nih.gov/articles/PMC8413259/).
Not supported by the evidence base
Marketers sell omega-3 broadly as a general life-extension and all-cause mortality supplement, but the highest-quality evidence does not support this. The 2018 Cochrane review, the most rigorous synthesis available, pooled 79 RCTs and 112,059 participants and found little or no effect of long-chain omega-3 on all-cause mortality (RR 0.98) or cardiovascular mortality, rated as high-quality evidence (https://pubmed.ncbi.nlm.nih.gov/30019766/). A 2022 dose-related metaanalys of 19 RCTs and 97,709 participants likewise found no statistically significant reduction in all-cause, cardiac, or stroke mortality at any studied dose (https://www.sciencedirect.com/science/article/abs/pii/S0261561422000735). For brain health, DHA supplementation shows benefit only in mild cognitive impairment, not in diagnosed Alzheimer's disease, per a review of RCT evidence (https://pubmed.ncbi.nlm.nih.gov/36637075/).
Typical dose
1 to 4 g/day combined EPA/DHA, with higher doses (2-4 g/day, EPA-predominant) used for triglyceride and cardiovascular-event reduction
Säkerhet
Omega-3 supplements are generally well tolerated at typical doses. The main documented risk is bleeding and, at high doses of purified EPA, atrial fibrillation. The 2021 metaanalys of 38 RCTs found increased AF risk with omega-3 supplementation, a known tradeoff against its cardiovascular mortality benefit (https://pmc.ncbi.nlm.nih.gov/articles/PMC8413259/). Fishy aftertaste and mild GI upset are common with lower-quality formulations. Choose produkter tested for oxidation and heavy metals.
