Gamma-linolenic acid (GLA) is used as an adjunct for conditions such as arthritis, eczema, and high blood pressure. Its use is very important during menopause as a soothing agent for its symptoms. Taking GLA for 6 to 12 months seems to help in the effort of pharmaceutical treatment to reduce symptoms and prevent nerve damage in people with nerve pain due to type 1 & 2 diabetes. It works best in people who have good blood sugar control.

GLA belongs to the category of Omega fatty acids and is a fatty substance found in various vegetable oils, such as evening primrose oil.
