Omega-3 Supplements Useless

A recent meta-analysis of 79 randomized controlled trials following more than 100,000 participants added to the growing corpus of non-findings. The study catalogued a long list of heart conditions for which omega-3s appear to have “little or no effect,” challenging the claimed benefit of the supplement, that taking it promotes heart health.
The rise of omega-3 supplements began when a team of Danish scientists, intrigued by reports of low rates of cardiac death among Inuit populations, embarked on an expedition to Greenland. They drew blood samples from local Inuit people and found far more omega-3 in their blood than in the blood of those in the Danish control group. Their hypothesis: Omega-3s are good for your heart.

The original claimed benefits for cardiac health were the first to fall after large randomized controlled trials showed few results. A 2012 meta-analysis came to the conclusion: “Overall, omega-3 … supplementation was not associated with a lower risk of all-cause mortality, cardiac death, sudden death, myocardial infarction, or stroke based on relative and absolute measures of association.”

Studies reported that omega-3 supplements do not help depression, do not help young children at risk for psychotic disorders, and do not improve the memories of the elderly.

Finally, during 2017, the Global Organization for EPA and DHA Omega-3s, a trade association, published a press release of its own study “Among randomized controlled trials, there was a non-statistically significant reduction in coronary heart disease risk with EPA+DHA provision.” Bottom line, save your money.
