Omega 3's or Essential Fatty Acids (EFA's) are required by the body for many functions such as mood stabilization, healthy skin, and as a tool to promote a healthy inflammatory response. EFA's are provided in the diet primarily by grass fed animals and cold water fish. EFA rich foods are missing in the American diet so supplementing with a high quality EFA such as Empirical Labs Salmon Oil is a useful tool for optimal health. Our Salmon Oil provides 100 mg EFA's as EPA & DHA per soft-gel and is purified to contain insignificant amounts of heavy metals.
