Evening Primrose Oil contains the essential fatty acid Gamma Linolenic Acid. Called essential because the body needs it for many purposes including helping to prevent blood clots that lead to strokes and heart attacks; helping to alleviate premenstrual syndrome or tension (PMS or PMT); supporting healthy skin, hair and nails and more.

Unfortunately the body can't manufacture essential fatty acids so it must be consumed in the diet or as a supplement.
