How does fish oil work?


Fish oil contains the omega-3 essential fatty acids docosahexaenoic acid (DHA) and eicosapentaenoic acid (EPA). This combination of polyunsaturated fatty acids works by lowering triglyceride levels in the body. Triglycerides are a type of fat (lipid) that travels through your bloodstream and stores excess calories for later conversion into energy. If you frequently eat more calories than you burn, you may develop high levels of triglyceride. This condition, called hypertriglyceridemia, increases your likelihood of heart disease, irregular heartbeats (cardiac arrhythmias), high blood pressure, and atherosclerosis (hardening of the arteries). By lowering triglyceride levels, fish oil may help treat or prevent these and other conditions.

But because these substances are unregulated, it is always a good idea to educate yourself about the products and to use common sense when taking them. This is even more true if you are pregnant or taking a medicine that may be affected by supplements.
