Both of these "omega" long-chain polyunsaturated fatty acids are substrates for a class of eicosanoids known as prostaglandins, which have roles throughout the human body. [36] The omega-3 eicosapentaenoic acid (EPA), which can be made in the human body from the omega-3 essential fatty acid alpha-linolenic acid (ALA), or taken in through marine ...
Though one's body produces peptides naturally, peptides are also found in many food and supplement sources. "All the food we eat is broken down by the body into amino acids," explains Stevenson.
To illustrate the amounts of EPA and DHA in supplements, a softgel capsule containing fish oil derived from pollock might contain a total of 642 mg of total fish oil, of which 584 mg are omega−3 fatty acids, with 377 mg EPA and 158 mg DHA. 3 That same company's salmon oil softgel contains 1008 mg of total fish oil, of which 295 mg are omega ...
