Omega-6 fatty acid supplements are often found through different forms of supplements, for instance, evening primrose oil (EPO).
These particular items can each have different side effects, and based upon which one is being considered for usage, that one should have its side effects considered.
In general, the dosage level should be stuck with. For instance, the overall gamma-linoleic acid intake should not go beyond 3000 mg in any given day.
Past that point, inflammation may be caused or further increased, as arachidonic acid production is raised. Lab studies have found that omega-6 fatty acids are able to promote prostate tumor cell growth, therefore, GLA and other omega-6 acids should not be used when there is a risk for prostate cancer (or symptoms of it).
When certain other supplements, medications, or herbal medicines are being used, there is the potential for interaction between them and omega-6 supplements. Before taking these supplements, tell your doctor about any other items you may be taking, and also do so if you are taking omega-6 prior to starting a new medicine, supplement, or herb.
Some of the possible interactions, not a complete list, include: blood thinning medications, cancer chemotherapy, phenothiazines, and others. Contraindications
Before you begin to take omega-6, tell your doctor about any existing medical conditions you may have. For instance, as mentioned in the side effects section, prostate cancer risk is a contraindication for taking this supplement.
One other such one is individuals with a seizure disorder. There could be many other contraindications, so get professional advice on this matter.
