Omega-3 fatty acids in the forms of DHA, EPA and ALA

Omega-3 fatty acids in the forms of DHA, EPA and ALA

Omega-3 fatty acids come in more than one form. 

The types found in fish, called DHA and EPA, have been studied most extensively and appear to have the strongest health benefits. 

Another form known as ALA is found in vegetable oils, flaxseed, walnuts, and dark leafy vegetables such as spinach. The body converts a small amount of ALA into EPA and DHA. 

ALA may also have some health benefits of its own.
