Omega- 3 and 6 fatty acids are considered essential fatty acids: They are necessary for human health but the body can’t make them — you have to get them through food. Omega-3 fatty acids and omega–6 fatty acids play a crucial role in brain function as well as normal growth and development. Also known as polyunsaturated fatty acids (PUFAs), they help stimulate skin and hair growth, maintain bone health, regulate metabolism, and maintain the reproductive system.
Omega-3 fatty acids can be found in seafood such as krill and fish like salmon. There are a few nut oils and plants like spirulina a blue green algae with small amounts of Omega–3. Because your body can't make omega-3 essential fatty acids (ALA,DHA,EPA) you need to get them from supplements or get them through your diet.
