2. Arthritis and Joint Inflammatory Diseases

Some studies have demonstrated that supplementation with evening primrose oil or black currant oil can

significantly reduce symptoms and signs of rheumatoid arthritis in double-blind, placebo-controlled, randomized

trials.

Other studies have failed to show improvement and researchers at ribute this failure to the ability of GLA to raise

tissue levels of arachidonic acid, while reducing cell membrane concentrations of omega-3 fat y acids. In these

cases fish, fish oil or flaxseed oil may be more beneficial. The dosage of GLA used in the successful studies

reported here used an oil yielding 2.8gm per day of GLA.18,19,20

3. Skin Inflammatory Conditions (Eczema, Psoriasis)

Supplementation with oils that yield GLA have demonstrated improvement in patients suffering from eczema

(atopic dermatitis) and psoriasis (GLA content of 274 mg, twice a day). - Studies using increased fish consumption

or fish oil supplementation have also shown benefit in patients with psoriasis.21-24

Dosage Ranges

For most conditions mentioned in this review supplementation of 270-540 mg GLA per day is typically used. This

implies that 3,000-6,000 mg of evening primrose oil would be required to yield this amount of pure GLA, as evening

primrose oil is 9 percent GLA content.

Side Effects and Toxicity

GLA is very non-toxic. Evening primrose oil has been reported to exacerbate symptoms of temporal lobe epilepsy,

which can sometimes be mistaken for schizophrenia.25,26

Drug-Nutrient Interactions

GLA-containing oils may increase seizure activity in patients taking anti-seizure medications.27

N.B. Concurrent supplementation of GLA, EPA, or LNA with a B-50 complex, vitamin E, vitamin C, zinc and

magnesium helps to encourage the synthesis of anti-inflammatory prostaglandins (series 1 and 3). These vitamins

and minerals act as cofactors to help catalyze enzymatic conversion of essential fatty acids to the more desirable

prostaglandins of the one and three series.1
