Spoiled Fish Oil Is Less Effective
6/06/2017
Spoiled fish oil does not lower LDL "bad" cholesterol, while the same amount of non-spoiled fish oil does, according to a new study.

Also see our Top Picks among fish oils.

Supplement vs. Prescription Fish Oil?
1/01/2017
As we have written before, by choosing an extremely concentrated fish oil supplement, you can get essentially the same type of fish oil as you would get from a prescription fish oil.

Fish Oil Helps in Schizophrenia
1/25/2016
A study found that concentrated fish oil greatly reduced symptoms in more people who had recently experienced a first episode of schizophrenia than did a placebo.

Don't Be Fooled by "Good Source of Omega-3s" Claim
7/09/2014
Over the years, ConsumerLab.com has pointed out that products sometimes claim to provide a percentage of the Daily Value (DV) of omega-3 or -6 fatty acids, even though no such Daily Value has been established.

Algal Oil vs. Fish Oil
12/19/2011
Fish get their omega-3's from algae and many people are now doing the same by taking algal oil, but how does it compare to fish oil? Experts recently reviewed studies of algal oil and concluded that it boosts ("good") cholesterol but it also increases LDL cholesterol -- which is often thought of as "bad" cholesterol. But there's more to the story. Get the details in the recently updated Fish/Marine Oil Supplements Review, which includes our test results for algal, krill, and fish oil supplements.
Concern with Rancid Fish Oil

See their conclusions in the Fish/Marine Oil Supplements Review, which includes our test results.
Fish Oil's Impact on Cognitive Decline
