The body needs essential fatty acids for its day-to-day functioning, including both omega-3s and omega-6 acids. Omega-3 is thought to be a natural anti-inflammatory, though is often lacking in the average diet. Omega-6 may be almost too prevalent in the average diet, though still essential for the human body. You can find essential fatty acids in supplements like fish oil, flaxseed and borage oil.
Fish Oil
Fish oil is one of the more common omega-3 supplements, and is often reputed for its contribution to heart health. The omega-3s in fish oil are DHA, or docosahexaenoic acid, and EPA, or eicosapentaenoic acid. Both play a role in controlling triglyceride levels in the body, which is related to your overall cholesterol level. Fish oil may also reduce high blood pressure for people who are diagnosed as hypertensive. By reducing many of these associated risk factors, fish oil supplements may indirectly decrease your risk of heart attack or stroke. It is available for purchase over the counter, in a variety of forms and strengths.
Flax Oil and Flax Seed
Flax oil and flax seed contain another important omega-3 fatty acid called alpha-linolenic acid, or ALA. Flax seeds may be sold whole, or in a ground form which can be taken in a caplet of sprinkled over foods. Like fish oil, flax oil usually comes in caplets. Both forms may be used to reduce some of the risk factors associated with heart disease. However, the National Center for Complementary and Alternative Medicine reports that there is little research on the effects of flax supplements in particular when it comes to heart disease prevention. They have, however, been marketed as a means to control symptoms associated with menopause. Flax contains natural plant estrogens which may reduce some hormone-related symptoms.
Borage Oil
Borage oil comes from the borage plant, and contains two different essential fatty acids: GLA, or gamma-linolenic acid, and LA, or linolenic acid. Both are omega-6 fatty acids, which differ from omega-3s in some of their properties. While the University of Maryland Medical Center reports that many omega-6 fatty acids promote inflammation, borage oil does have some health benefits when used accordingly. Borage oil has been studied for its effects on eczema as well as rheumatoid arthritis, and shows promise for use in the treatment of both.
Advice for Supplement Use
You should never try a new supplement without first consulting with your doctor. Even natural, over-the-counter products may have unpleasant side effects, and may not be safe for everyone. In addition, natural remedies can interact with certain medications. While some people may prefer taking a dietary supplement, you can also increase the amount of omega-3 and omega-6 rich foods in your diet for some of the same health benefits. Cold water fish, soybeans and walnuts are all high in omega-3 fatty acids. You can also find omega-6 fatty acids in many vegetable oils.
