GLA
Gamma-linolenic acid — an omega-6 fatty acid with anti-inflammatory effects. Found in evening primrose oil and borage oil.
What is GLA?
Gamma-linolenic acid (GLA) is an omega-6 fatty acid that plays an important role in our diet and health. GLA is a polyunsaturated fatty acid naturally found in certain plant oils, primarily evening primrose oil and borage oil. Although GLA is classified as an omega-6 fatty acid, which often has a negative connotation in discussions about fats, it has specific health benefits that research has begun to explore in more detail.
How does it work in the body?
GLA is converted in the body into prostaglandins, which are hormone-like substances with an important role in regulating many physiological processes, including inflammation and immune response. By promoting the production of anti-inflammatory prostaglandins, GLA may help reduce inflammation and support overall health.
Scientific benefits
Several studies have investigated the potential health benefits of GLA. Here are some of the most prominent areas where research has shown promising results:
- Inflammation: Several studies have shown that GLA may help reduce inflammation, which is important for managing conditions such as arthritis and other inflammatory diseases.
- Skin health: Research has shown that GLA can improve skin condition, particularly in conditions such as eczema and psoriasis, by supporting the skin's barrier function.
- Menstrual discomfort: Some studies have indicated that GLA may help alleviate symptoms of PMS and menstrual-related pain through its anti-inflammatory properties.
It is important to note that more research is needed to fully understand the effects and mechanisms of GLA in the body, but the initial results are promising.
Dosage and recommendations
The recommended dosage of GLA can vary depending on individual needs and health conditions. Generally, a dose between 500 mg and 3000 mg per day is recommended, depending on the type of condition one wishes to support. It is always best to consult a doctor or other qualified healthcare professional before starting supplements containing GLA.
Best sources and forms
GLA is primarily found in the following sources:
- Evening primrose oil: One of the most popular sources of GLA, often used in supplements.
- Borage oil: Another rich source of GLA, known for its health-promoting properties.
- Blackcurrant seed oil: Also contains GLA and is used for its potential health benefits.
It is important to choose high-quality products from reputable manufacturers to ensure an effective dose of GLA.
Side effects and warnings
GLA is generally considered safe when taken at recommended doses. However, some people may experience side effects such as:
- Gastrointestinal discomfort
- Nausea
- Diarrhoea
Individuals taking blood-thinning medications or with a history of epilepsy should exercise caution and consult a doctor before using GLA supplements. Pregnant and breastfeeding women should also consult a doctor before using GLA.
