Micronutrients & recovery
Omega-3 polyunsaturated fatty acids (EPA/DHA) reduce cardiovascular risk in observational studies, but randomized controlled trials of supplementation do not consistently show a reduction in major cardiovascular events.
Eating fish is associated with lower heart disease risk, but taking omega-3 supplements does not consistently prevent heart attacks or strokes in clinical trials. If you want the benefits, focus on eating fatty fish rather than relying on supplements.
Most of the findings indicated that consumption of fish oil significantly causes reduced mortality from cardiac events... However, not all clinical trials confirmed the reduction in cardiovascular outcomes after omega-3 PUFA intake.
Why this rating
Based on conflicting evidence from observational studies and RCTs, with some RCTs showing benefit and others showing none.

- Replacing saturated fatty acids (SFAs) with polyunsaturated fatty acids (PUFAs) reduces cardiovascular disease risk, whereas replacing SFAs with carbohydrates or proteins provides no benefit.Good
- Trans fatty acids (TFAs) from industrial hydrogenation increase coronary heart disease risk and should be avoided, while naturally occurring TFAs from ruminant sources (dairy/meat) show no adverse effect or potential benefit.Good
