Evening Primrose Oil (EPO) comes from the seeds of the evening primrose plant. Like blackcurrant seed oil and borage oil, EPO contains gamma linolenic acid (GLA), a fatty acid that the body converts to a hormone-like substance called prostaglandin E1 (PEG1).Where is it found ?EPO is found primarily in supplements. Its presumed active ingredient, GLA can also be found in blackcurrant seed oil and borage oil supplements. EPO may help to maintain normal bodily functions and may maintain the health of skin, hair and nails.Who is likely to be deficient ?Those with hormone imbalance and skin conditions, can have a metabolic block that interferes with the body\'s ability to make GLA. There is evidence that alcoholics may be deficient in GLA. - 120 (size H)
