Fish-oil supplements, which have gotten some credit for helping prevent everything from memory loss to heart disease, are coming under extra scrutiny lately.
Two extensive studies are now casting doubt on the supplements’ benefits — suggesting that now might be a good time for those supposedly potent pills to go the way of your late pet goldfish.
Fish oil is the most commonly taken natural supplement among both adults and children, with 18.8 million US adults popping them regularly, a National Health Interview Survey found.
“People need to be a little skeptical,” he says, adding that he would not personally take a fish-oil supplement for any health reason.
Here’s a look at recent findings on omega-3.

Overall, the trials revealed that those supplements had a little-to-no benefit to diabetes patients compared to a placebo.
Another large study, published in July’s edition of the Annals of Internal Medicine, investigated several supplements targeted at heart health. It found that evidence for omega-3 supplements such as fish-oil pills had a “low level of certainty” when it came to avoiding myocardial infarction and coronary heart disease.
