Gamma Linolenic Acid

Hello Dr. Rassman,

On wikipedia I read that gamma linolenic can inhibit 5 alpha-reductase. I was wondering how effective taking gla would be and if you have observed its affect on anyone. Thank you ahead of time.

Gamma-linolenic acid (GLA) is an essential fatty acid (EFA) in the omega-6 family that is found primarily in plant-based oils. You likely eat GLA every day if you eat food prepared with plant-based oils. The internet is a wonderful resource and sites such as Wikipedia have lots of information, but sometimes too much information can be confusing and misleading. GLA to my knowledge has not been observed to grow hair.

There are many oral vitamins and minerals which have suggestive evidence for preventing hair loss. This site may have interest for our readers, but I can not take a position on the recommendations it contains.
