Fish oil supplements are generally provided as a rich source of the omega-3 polyunsaturated fatty acids eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA). Omega 3 fatty acids are important to human nutrition, and cannot be synthesized by the body. As such, they are regarded as essential dietary nutrients. The consumption of small amounts of these essential fatty acids is necessary for many biological functions including human growth and development, cell membrane functioning, nutrient metabolism, nervous system functioning, vision, memory, and cognition. In sports nutrition, fish oil supplements are widely used for their potential benefits on metabolism and overall health.
