The side effects of omega-3 supplements are usually mild. They include an unpleasant taste, bad breath, foul-smelling sweat, headache, and gastrointestinal symptoms such as heartburn, nausea and diarrhea. Several major studies have linked higher levels of long-chain omega-3 in the blood to an increased risk of prostate cancer. Omega-3 is an essential part of the diet and supplements, such as fish oil, have been associated with a number of health benefits.
Fish oil is a dietary source of omega-3 fatty acids. The body needs omega-3 fatty acids for many functions, from muscle activity to cell growth. Omega-3 fatty acids are essential for good health. Try to eliminate them from your diet by eating roasted or baked fish, not fried.
Fish oil supplements may be helpful if you have high triglyceride levels or rheumatoid arthritis.
