GLA supplements, made from plant sources like evening primrose oil and borage oil, contain omega-6 fatty acids that can reduce inflammation and promote cognitive function, growth, and development. They should be packaged in light-resistant containers, refrigerated, and adhere to FDA labeling and GMP regulations. GLA supplements can be used for various purposes, including arthritis, allergies, and high blood pressure, and take up to six months to show benefits.
GLA, or gamma-linolenic acid, is a type of essential fatty acid that is obtained from plant resources. GLA supplements are available in liquid and capsule forms and are made from sources such as evening primrose oil and borage oil. A reliable supplement must be packaged in a light-resistant container, sealed with an expiration or freshness date, and follow FDA-required labeling practices. Supplements should also be refrigerated due to their susceptibility to rancidity.
GLA supplements contain omega-6 fatty acids, which play an important role in health, specifically cognitive function, as well as human growth and development. A healthy diet consists of a balance of omega-3 and omega-6 fatty acids, generally containing a 2:1 to 4:1 ratio, omega-6 to omega-3 fatty acids. While many types of omega-6 fatty acids promote inflammation, a GLA supplement can actually reduce inflammation. This occurs when the body converts GLA into dihomo-gamma-linolenic acid, an inflammation-fighting compound.
The fatty acids contained in a GLA supplement are also called polyunsaturated fatty acids (PUFAs). PUFAs fall into three main categories, including omega-3, omega-6, and omega-9 fatty acids. They play a vital role in promoting skin and hair growth, as well as helping to regulate metabolism and the reproductive system.
A solid supplement option will adhere to the Good Manufacturing Practice (GMP) requirements of the Food and Drug Administration. GMP regulations require dietary supplement companies, such as manufacturers, to guarantee the purity, strength, and composition of their supplements. A reliable supplement is produced by a well-established and reputable company that complies with GMP regulations and is tested by an independent quality testing organization.
The body uses gamma-linolenic acids to produce hormone-like substances, prostaglandins, which promote proper cell function and help regulate the immune system. A GLA supplement can be given for a variety of purposes, including arthritis, allergies, PMS, osteoporosis, and high blood pressure. Supplements may also help fight certain cancers, multiple sclerosis, and attention deficit hyperactivity disorder.
While evening primrose oil is the most common source of fatty acids for GLA supplements, other sources include borage oil, flax oil, mushroom oil, and blackcurrant oil. Supplements generally range in strength from 0.02 ounces (about 500 mg) to .1 ounces (about 3000 mg) and can contain 8 to 10 percent gamma-linolenic acid. The benefits of taking a supplement can take up to six months to manifest. No contraindications or serious side effects have been reported with GLA supplementation.
