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. But according to a recent study, fish oil supplements are more likely to be rancid (oxidized) than prescription fish oil.
