Gamma Linolenic Acid, or GLA, is an omega-6 fatty acid that can be made in your body from an essential fatty acid called linoleic acid. These substances are responsible for reducing inflammation and cell growth. Normally, the body produces enough GLA from linoleic acid, but diabetics, alcohol abusers, people with viral infections, people with high cholesterol, and people who are deficient in vitamin B6 may not produce enough. There are many health benefits to GLA, and one of the most notable is its ability to reduce inflammation. Inflammation can be a sign of many chronic diseases like cancer, diabetes, heart disease, and arthritis. One to three months of taking GLA supplements may help reduce pain, swelling, and morning stiffness associated with rheumatoid arthritis. There is reasonable scientific evidence that GLA can improve ADHD. Omega-6 and Omega-3 fatty acids are essential in normal brain function because the brain is about 60% fat. Studies have shown that GLA and eicosapentaenoic acid could provide some benefits in treating ADHD symptoms. In a study involving obese participants, GLA was found to play a role in maintaining a healthy body weight. This was especially true after major weight loss. Participants who were given GLA regained less weight compared to those who were not given GLA, suggesting that it might be useful for those who are prone to obesity. Other health benefits of gamma linolenic acid are treatment and prevention of eczema, and preventing a GLA deficiency that can cause diabetic neuropathy in diabetic patients.

Gamma linolenic acid can be found in small amounts in food but our body can produce GLA from linoleic acid, which can be found in a lot of foods. Some foods that have the highest amount of GLA include evening primrose oil, hemp oil, black currant, and spirulina. Reported side effects are occasional headaches, abdominal pain, and nausea when taken in high doses. People with seizure disorders should avoid GLA. Interaction may occur with other drugs so it’s best to consult your doctor before taking it.
