what it claims

Taking an omega-3 supplement in capsule form is a simple and effective solution for supporting heart health, brain health, and general well-being, as it is difficult to consume enough through diet alone.

Omega-3 intake is essential to our vitality, and it is true that reaching recommended levels through diet alone can be a challenge for many people.

Omega-3 intake is essential to our vitality, and it is true that reaching recommended levels through diet alone can be a challenge for many people. However, the idea that capsule supplements offer the same benefits for the heart and mind as whole foods is scientifically nuanced. A vast meta-analysis from the Cochrane Library revealed that omega-3 supplementation provided little to no measurable protective effects on heart health compared to a standard diet. Regarding mental sharpness, a randomized clinical trial from the University of Southern California (USC) published in eBioMedicine showed that taking DHA in capsules did not improve memory or cognitive faculties in adults. Furthermore, experts at the Cleveland Clinic note that healthy fats are always better absorbed and more beneficial when consumed directly on the plate, via fish such as salmon. Thus, although these small formats greatly facilitate daily nutrient intake, they do not constitute a miracle solution to replace the benefits of a balanced meal.

What the graded evidence says

Effect
cardiovascular mortality / events; atrial fibrillation; mood — EPA monotherapy RR 0.82 (0.68-0.99) for CV mortality vs weak EPA+DHA RR 0.94 (0.89-0.99); AF increased RR 1.26 (1.08-1.48); mood SMD -0.28 (EPA-predominant, dose <=1 g/day)
Measured on
general adults (primary prevention), high-triglyceride statin-treated adults, adults with low mood

What’s uncertain

The heart benefits people expect from everyday fish-oil pills largely didn't show up in big trials. Real benefit is narrow (high-dose EPA, high triglycerides) and high doses carry a small atrial-fibrillation and bleeding trade-off.
