A generic descriptor for all tocopherols and tocotrienols that exhibit alpha-tocopherol activity. By virtue of the phenolic hydrogen on the 2H-1-benzopyran-6-ol nucleus, these compounds exhibit varying degree of antioxidant activity, depending on the site and number of methyl groups and the type of isoprenoids.

Omega-3 fatty acids are polyunsaturated fatty acids (PUFAs) with a double bond at the third carbon atom from the end of the carbon chain. The three types of omega-3 fatty acids involved in human physiology are α-linolenic acid (ALA) (found in plant oils), eicosapentaenoic acid (EPA), and docosahexaenoic acid (DHA) (both commonly found in fish oil that originally come from microalgae that is further consumed by phytoplankton, a source of diet for fish). Omega-3 fatty acids play a critical role in metabolism and cellular function and they are available as daily supplements. On September 8, 2004, the U.S. Food and Drug Administration gave “qualified health claim” status to EPA and DHA omega-3 fatty acids. Therapeutic products containing omega-3 fatty acid and its derivatives for treatment of hypertriglyceridemia include Lovaza, Omtryg, Epanova, and Vascepa.

Some adverse effects experienced in patients include gastrointestinal disturbances such as vomiting and constipation, metabolic disorders and skin reactions.

Vitamin E, known for its antioxidant activities, is protective against cardiovascular disease and some forms of cancer and has also demonstrated immune-enhancing effects. It may be of limited benefit in some with asthma and rheumatoid arthritis. It may be helpful in some neurological diseases including Alzheimer’s, some eye disorders including cataracts, and diabetes and premenstrual syndrome. It may also help protect skin from ultraviolet irradiation although claims that it reverses skin aging, enhances male fertility and exercise performance are poorly supported. It may help relieve some muscle cramps.

Provided as daily supplements. Aa preparation of omega-3-acid ethyl esters is licensed in UK for prevention of recurrent events after myocardial infarction in addition to treatment of hypertriglyceridaemia.
