DHA, Docosahexaenoic acid or cervonic acid is an omega 3 essential fatty acid, a carboxylic acid commonly found in fish oils and microalgae. DHA is found in beef and eggs, but can be derived from eicosapentaenoic acid, EPA, through docosapentaenoic acid, DPA. DHA has been discovered to restrain colon carcinoma cells in humans. DHA is found in large numbers in human brain and retina, half of plasma membranes of neurons is Docosahexaenoic acid. In recent times, due to changes in farming, DHA levels in common food have been decreasing, prompting the use of DHA as a food additive. DHA as a nutritional supplement is widely viewed as vital, Docosahexaenoic acid is also very often found in nutritional supplement compounds designated for pregnant women.

EPA (Eicosapentaenoic Acid), also known as icosapentaenoic acid and EPA, is a omega 3 fatty acid, a carboxylic acid which acts as a precursor for prostaglandin 3, thromboxane 3 and leukotriene 5 groups of eicosanoids. It is mostly found in fish oil, but can also be contained in human breast milk. In recent times, sources from microalgae have been preferred, due to the large quantities of toxins contained in fish swimming in polluted waters. Human body can produce EPA out of alpha linoleic acid, but since that ALA is an essential fatty acid, only excess amounts would be converted. EPA has been subject to studies pertaining to the use in treatment of schizophrenia, but it may also lower suicidal tendencies. Further use as breast cancer progression inhibitor is under investigation.

Fish Oil is the extracted oil from tissues of oily fishes such as tuna, mackerel and salmon. It is rich in unsaturated fatty acids called Omega-3. Due to its Omega-3 content, fish oil is widely used for health purposes since Omega-3 is known to aid in reducing the risk of heart attacks as well as other coronary heart ailments. Also, research shows that fish oil also has something to do with the regulation of cholesterol levels and keeping blood pressure at bay. Fish oil has also shown potentials to benefit mental health. Studies show that it can enhance memory and concentration, as well as prevent depression.

Vitamin E, an anti-oxidant nutrient, neutralizes free radicals in the human body to prevent cell damage. This fat-soluble vitamin not only aids the formation of red blood cells but also helps in the absorption of vitamins A, C and K. It is also very helpful to fight various ailments. Since the human body cannot produce vitamin E on its own; it has to be incorporated in our daily diet. This can be done either by consuming foods that are rich in vitamin E or by taking vitamin E supplements. The RDA for adult males is 10 mg. while 8 mg. is the daily requirement for adult females. Expecting and nursing women should compulsorily take 10 mg. of vitamin E supplements. Vitamin E supplements are most effective when consumed with food.
