Omega-3 (EPA/DHA)
halolaj · fish oil · Fischöl · algaolaj
A stand-in for two weekly servings of oily fish; high-dose EPA lowered cardiovascular risk.
4/5· RCTs / large cohortsEstimated monthly cost: ≈ 12 €
Dose
1–2 g EPA+DHA daily (that's the fatty-acid content, not capsule weight). Algal oil for vegans.
Timing
With food; frozen capsules cause less reflux.
⚠ Cautions
May prolong bleeding time with anticoagulants; high doses slightly raised atrial-fibrillation risk. Oxidised (rancid) product is worse than none.
What it is
Long-chain polyunsaturated fatty acids: membrane components and precursors of pro-resolving mediators.
What the evidence shows
In REDUCE-IT, 4 g/day purified EPA cut major cardiovascular events by 25% in statin-treated patients. One-gram mixed fish oil (VITAL, ASCEND) showed no clear overall effect, but did in people who rarely eat fish. An omega-3 index ≥8% tracks with lower mortality in cohorts.
