Not all omega-3s are created equal. Among 11 types, the 3 most important are alpha-linolenic acid (ALA), eicosapentaenoic acid (EPA), and docosahexaenoic acid (DHA). ALA is found mainly in plant oils such as flaxseed, soybean, and canola oils. DHA and EPA are found in fish and other seafood.
EPA is an important omega-3 fatty acid that has come to prominence over the last several decades. Fatty fish, such as salmon, herring, sardines, mackerel, tuna, halibut, cod liver, whale blubber, or seal blubber. and others, is the best food source for EPA. It is also found in fish oil supplements, along with docosahexaenoic acid (DHA). Fortified foods, such as orange juice or eggs, may contain omega-3 EPA.
EPA prevents the blood from clotting easily, reduces triglyceride levels in the blood, and has effects that might reduce pain and swelling.
Fish oil is high in EPA and DHA, may reduce symptoms of depression. Some evidence suggests that EPA is superior to DHA in this regard. EPA is used in combination with RNA and L-arginine after surgery to reduce infections, improve wound healing, and shorten recovery time.
