Omega-3 (EPA/DHA)
Evidence: ★★★★★ · Status: OTC Supplement, FDA Approved
In plain English
These are the fish-oil fats your cell walls are built from. They calm inflammation and lower blood fats — most useful if you don't eat oily fish 2–3× a week.
How it works
EPA and DHA incorporate into cell-membrane phospholipids and are converted to anti-inflammatory eicosanoids (resolvins, protectins). They activate PPARα and the fatty-acid receptor FFAR4 (GPR120), lower hepatic triglyceride synthesis, and reduce NF-κB-driven cytokines (IL-6, CRP).
Molecular target & official sources
FFAR4/GPR120 (NCBI Gene) · PPARA (NCBI Gene) · EPA (PubChem CID 446284)
Protocol
1–3 g combined EPA+DHA/day with a fatty meal. Check label — a 1 g capsule may be only 300 mg EPA+DHA.
Watch out
Blood-thinning >3 g/day; slight AFib signal at 4 g.
Bottom line
Rare supplement with strong evidence across heart, joints, and brain.
Helps with: Recover Faster · Live Longer · Joint Health · Cardiovascular · Stress & Anxiety
The human evidence
REDUCE-IT (2018, ~8,000 high-risk patients already on statins) found high-dose purified EPA cut major cardiovascular events by roughly a quarter — but broader trials of general fish oil in lower-risk people have been largely null. The strong signal is specific to high-dose EPA in high-triglyceride, high-risk people.
Stacks with
Take with a fatty meal for absorption; often paired with vitamin D.
Shares a pathway — often paired with: Vitamin D3 (+ K2), Testosterone (TRT), Finasteride / Dutasteride, Tretinoin / Retinoids.
Avoid combining with
High doses (>3 g/day) alongside blood thinners (warfarin, aspirin) — additive bleeding risk. Stop ~1 week before surgery.
Availability & where to buy
Available over the counter. Widely available OTC — e.g. iHerb (ships worldwide); in Singapore also Guardian, Watsons, GNC, Shopee / Lazada. Look for a third-party-tested / GMP mark and check the dose per serving. ~S$20–45/month. Buy on total EPA+DHA (read the back), not the “1000 mg fish oil” on the front.
