The question with Omega-3 fatty acids: Where to begin when listing the benefits? These polyunsaturated fats are found naturally in fish and vegetable oils (especially flaxseed oil), and they play an important role in a number of body functions.
As a health supplement, omega-3s lower fats in the body called triglycerides, which are associated with heart disease and diabetes. Taking fish oil supplements may lower blood pressure slightly, slow the hardening of arteries and help prevent cardiovascular disease. In addition to helping people with healthy hearts keep them that way, omega-3 fatty acids can also lower the risk of dying from heart disease for those people who already have cardiovascular problems.
As if this weren't enough, studies have shown that fish oil may have additional benefits for a number of other diseases and conditions. The science is sometimes inconclusive, but the NIH considers that fish oil may possibly be effective for treating kidney problems, certain types of cancer, depression, asthma, rheumatoid arthritis and a whole list of other medical conditions. In short, if there's one supplement you want in your daily regimen, it's fish oil.
