Evening Primrose Oil is one of the few natural sources of a polyunsaturated fatty acid called GLA (GLA), which is the precursor of a particularly important prostaglandin, PGE1, which is involved in the regulation of the nervous, cardiovascular and reproductive systems, skin health and a multitude of other biological functions. Although the body can produce GLA from Linoleic Acid (the Omega 6 fatty acid found in vegetable oils), this conversion is often slowed or even completely inhibited. For this reason, a dietary source of GLA may be useful for the body to bypass the conversion process, which is confirmed by several clinical studies in which the benefit of taking GLA supplements was demonstrated in specific cases.
