Omega-3s are a family of fats that are important for your health. Alpha-linolenic acid (ALA) is an essential dietary fat. You need ALA to make other omega-3 fats called long-chain (LCN-3). Eicosapentaenoic acid (EPA) and Docosahexaenoic acid (DHA) are LCN-3 fats. ALA makes these in your body. This happens slowly and only small amounts are formed.

Where do omega3 fatty acids come from?

Omega−3 fatty acids are formed in the chloroplasts of green leaves and algae. While seaweeds and algae are the sources of omega−3 fatty acids present in fish, grass is the source of omega−3 fatty acids present in grass-fed animals.
