Omega-3s in stability

The 2-key omega-3 fatty acids are docosahexaenoic acid (DHA) and eicosapentaenoic acid (EPA). Fatty fish like salmon, mackerel, and sardines are wealthy in these omega-3s. Some crops are wealthy in one other sort of omega-3 fatty acid, alpha-linolenic acid, which the physique can convert to DHA and EPA.
