A rich botanical source of GLA

Evening Primrose Oil, a natural source of gamma-linolenic acid (GLA), is well known for modifying the inflammatory response and maintaining hormonal balance. This versatile oil comes from the tiny seeds of a wildflower, Oenothera biennis L., native to North America, and has been studied for its positive influence on prostaglandin synthesis. GLA may also support the healthy growth and maintenance of skin, hair, and nails.

All of the evening primrose oil used in the Weil formula is cold pressed without the use of solvents. Weil Evening Primrose Oil is encapsulated exclusively in vegetarian, liquid-filled capsules.

'Evening primrose oil is a natural source of a fatty acid called GLA (gamma-linolenic acid). Very hard to come by in the diet, GLA is an effective anti-inflammatory agent with none of the side effects of anti-inflammatory drugs. It also promotes healthy growth of skin, hair, and nails. I frequently suggest evening primrose oil for skin conditions (including brittle nails and hair), arthritis, autoimmune disorders, and premenstrual syndrome. Do not expect immediate results; it takes six to eight weeks to see changes after adding GLA to the diet.' - Andrew Weil, M.D
