I believe this is good advice by jc76. The best supplemental oils have DHA (docosa
hexaaenoic acid). Said: doe KO sa hexa aaynoik acid, but DHA is widely understood). Also, you want omega 3 and not so much omega 6, although if either is present and 'young' (bottle not stale dated per the 'best before' or expiry date, and if the product is consumed inside of about six weeks, AND it is kept sealed and in a refrigerator) they are both readily usable by the body. Just be careful of stale oils not properly stored, not consumed in a few weeks at most, and that have not been exposed to room temps and to oxygen much (they go rancid, and with that comes inflammation when they are ingested).
