Omega-3 is an important fatty acid that is necessary for the body but is not produced in the body and must be taken from the outside. Omega-3 is an important component of lipid metabolism in animals, that is, the conversion of fat into energy by the body and is widely found in nature. Omega 3 has important roles in human nutrition and physiology. The human body needs Omega 3 fatty acids for many functions, from muscle activity to cell growth. Fish oil primarily contains two types of omega-3 fatty acids eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA), which are known to be beneficial for heart health and skin. However, fish oil has an incredibly positive effect on the brain, especially when it comes to mild memory loss and depression. It is critical at all stages of life for the maintenance and development of normal brain functions.
