Fish oils are found in the tissues of fatty fishes. Especially rich sources are cold water species such as mackerel, herring, sardine, pilchard, and salmon. What is special about these oils is that they contain abundant amounts of polyunsaturated essential fatty acids of the omega-3 type, the most important of which are eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA).

Since being recognized in the 1970s for their health benefits, these key dietary supplements have been the subject of literally thousands of scientific trials. These studies have verified the efficacy of omega-3 acids in both protecting people from disease and treating those who already suffer from a range of illnesses.

Included among the claimed health benefits of fish-oil supplements are:

Lowering of triglycerides. High levels of triglycerides have been linked to atherosclerosis, which leads to heart disease and stroke.
Reduced hypertension. Hypertension is one of the risk factors for heart failure and strokes, as well as chronic renal failure.
Reduced pain and swelling in joints.
Improvement in autoimmune diseases such as rheumatoid arthritis, Crohn’s disease, and lupus.
Prevention of death in those who have already suffered heart attacks.
Ability to decrease clotting tendencies of the blood.
Alleviation of symptoms of PMS and menopause.
Stabilization of mood for those suffering from bipolar disorder.
Reduced risk of asthma.

Although the many benefits of omega-3 fatty acids can be obtained by eating a diet rich in these substances, it is an unfortunate fact that many people on a standard American diet simply miss out on the appropriate foods. The good news, however, is that fish-oil supplements are both readily available and they provide an easy way to ensure that the whole family receives adequate omega-3 intake.

The best way to achieve this vital supplementation is by taking Omega-3 capsules. This product is a rich source of natural fish oil, highly concentrated in the two most important ingredients—EPA and DHA. It is so concentrated in fact that it has twice the amount of omega-3 as other fish-oil supplements. Moreover, as the oil is extracted from the fish at low temperatures without the use of harsh solvents, you are assured of a high-grade, clean product.

There have been no reports of serious adverse side-effects from people taking fish oil supplements, even for doses up to 15 grams per day for prolonged periods of time. However, children, pregnant women, nursing mothers, and those with serious illnesses should take fish oil supplements under the guidance of their doctor.
