Evening Primrose Oil 1300 mg. (60 Capsules)
What does it do? Evening primrose oil (EPO), black currant seed oil, and borage oil contain gamma linolenic acid (GLA), a fatty acid that the body converts to a hormone-like substance called prostaglandin E1 (PGE1). PGE1 has anti-inflammatory properties and may also act as a blood thinner and blood vessel dilator.
The anti-inflammatory properties of EPO have been studied in double blind research with people suffering from rheumatoid arthritis. Some, but not all, studies have reported that EPO supplementation provides significant benefit to these people.
GLA, the primary active ingredient in EPO, has anti-cancer activity in test tube studies and in some, but not all, animal studies. Injecting GLA into tumors has caused regression of cancer in people in preliminary research. Very preliminary evidence in people with cancer suggested “marked subjective improvement,” though not all studies find GLA helpful.
EPO has been reported to lower cholesterol levels in people in some, but not all, research.
Linoleic acid, a common fatty acid found in nuts, seeds, and most vegetable oils (including EPO), should theoretically convert to PGE1. But many things can interfere with this conversion, including disease, the aging process, saturated fat, hydrogenated oils, blood sugar problems, and inadequate vitamin C, magnesium, zinc, and B vitamins. Supplements that provide GLA circumvent these conversion problems, leading to more predictable formation of PGE1.
Where is it found? EPO is found primarily in supplements. The active ingredient, GLA, can also be found in black current seed oil and borage oil supplements.
Who is likely to be deficient? Those with premenstrual syndrome, diabetes, scleroderma, Sjogren’s syndrome, tardive dyskinesia, and eczema, and other skin conditions can have a metabolic block that interferes with the body’s ability to make GLA. In preliminary research, supplementation with EPO has helped people with these conditions.
Though preliminary, double blind evidence suggests that alcoholics may be deficient in GLA and that alcohol withdrawal may be facilitated with EPO supplementation. Many people in Western societies may be at least partially GLA deficient as a result of aging, glucose intolerance, dietary fat intake, and other problems. Individuals with deficiencies benefit from supplemental GLA intake from EPO, black currant seed oil, or borage oil.
How much is usually taken? Although many people may have inadequate levels of GLA, the optimal intake for this nutrient remains unknown. Researchers often use 3,000–6,000 mg of EPO per day, which provides approximately 270–540 mg of GLA.
Are there any side effects or interactions? Consistent, reproducible problems from taking EPO have not been reported.
