Gamma-linolenic acid (GLA) is an omega-6 fatty acid found in evening primrose oil, borage oil, and black currant seed oil. The body converts GLA into hormone-like compounds that help maintain skin health and joint comfort.
Many people use GLA to soothe dry, irritated skin. The supplement also helps with joint comfort and hormonal balance during the menstrual cycle.
Take GLA with food to boost absorption. It can take several weeks before you notice any changes. GLA slows blood clotting and may raise bleeding risk when combined with anticoagulant or antiplatelet drugs. Stop taking it two weeks before any surgery.
