How does Omega-3 from plant sources differ from Omega-3 from fish oil?

Fish oils contain Omega-3s (long chain fatty acid) that are slightly different from the Omega-3s found in plants (short chain fatty acid.) Fish have the ability to convert linolenic acid to DHA and EPA which are the end products that are beneficial to humans. Humans can convert the linolenic acid from plant sources into EPA and DHA to a very limited degree. Therefore, the beneficial effects of DHA and EPA are more available from fish oil sources rather than plant sources. However, despite this fact, I am happy if people take ANY kind of Omega-3 rich foods, whether it is from fish, or from plants. Fish oil supplements come in liquid and capsule form and come in different concentrations and quality. Be sure to look out for pharmaceutical grade when buying fish oil supplements.
