Gamma-linolenic acid, or GLA, is a type of essential fatty acid mainly found in plant-based oils. Typically, the body makes enough GLA from linoleic acid, but certain individuals may have difficulty converting linoleic acid to GLA. Diabetics, frequent alcohol users, those with viral infections, people with high cholesterol, and people deficient in vitamin B-6 may need additional GLA supplementation.
Evening Primrose Oil
Evening primrose oil is made from the seeds of evening primrose. Its active ingredient is GLA, and it has a number of potential uses. Of those listed, however, the oil has only been shown to be likely effective for mastalgia and osteoporosis. There also has been some evidence that it may help those with rheumatoid arthritis.
Hemp Oil
Though it lacks vitamins and antioxidants, hemp oil is a good source of GLA. It's made from hemp seeds and can be used as a dietary supplement or is added to body care products. It is said to promote healthy hair, skin, and nails and be used as an anti-inflammatory. Heating or cooking with hemp oil reduces its nutritional content.
Black Currant
The Mayo Clinic lists black currant oil as an alternative medicine treatment option for rheumatoid arthritis. There's no set dosage, but serious side effects such as liver damage may occur. Consult your physician before using this or any other supplement to ensure safety.
Spirulina
Spirulina is a blue-green algae high in vitamins, minerals, and antioxidants; 62 percent of spirulina is amino acids and it is the highest food source of GLA. The dietary supplement is found in pill, powder, of flake form.
Side Effects
GLAs should not be taken by those with seizure disorders. Adults should not exceed 3,000 mg per day. Some people experience occasional headaches, abdominal pain, and nausea. Certain medications may caused interactions when mixed with gamma-linolenic acids, and doctor supervision is recommended.
