There are several types of omega-3 fatty acids. Two crucial ones -- EPA and DHA -- are primarily found in certain fish. Plants like flax contain ALA, an omega-3 fatty acid that is only partially converted into DHA and EPA in the body.
Experts say that DHA and EPA -- from fish and fish oil -- have better established health benefits than ALA. Too little of ALA actually converts to DHA and EPA in the body.
DHA and EPA are found together only in fatty fish and algae. DHA can also be found on its own in algae.
