Please note that this section reports on claims that have not yet been substantiated through scientific studies.
The GLA from borage oil and other botanical oils may reduce inflammation. This may aid in arthritis. It may also reduce allergy symptoms.
Sources vary on the amount of borage oil you should use. This is likely due to the many issues it may treat. You should follow the directions on the package for the correct dose.
Women who are pregnant or breastfeeding should not use borage oil.
GLA is said to be relatively safe. However, there are concerns that borage oil may be toxic. Evening primrose oil seems to be a safer source of GLA than borage oil.
Both borage oil and evening primrose oil may lower the seizure threshold. People who take anticonvulsant medicines should not take these oils. Some omega-6 fatty acids, such as GLA, may increase or decrease the effects of certain medicines. Talk to your healthcare provider before taking borage oil.
The combined essential fatty acids (omega-3 and omega-6) should make up 1 to 2 percent of your total caloric intake. The recommended ratio of omega-3 to omega-6 fatty acids is 1:1 or 1:2. Because of the increased use of vegetable oil in the U.S., most American diets are closer to 1:20 to 1:30.
Borage oil contains about 18–26% GLA. Other plant oils also contain GLA. Evening primrose contains between 7–10%. Black currant oil contains 15–20%.
