Omega 3 (especially EPA and DHA) is very important for the human body: it helps many metabolic processes and our bodies greatly benefit from it if we ingest enough of it. Fish oil is the main natural source of EPA and DHA. A daily intake of 2 g of EPA and DHA helps to maintain normal triglycerides levels in the blood. A daily intake of 250 mg of EPA and DHA contributes to proper cardiac function. A daily intake of 250 mg of DHA contributes to normal brain and vision function. Omega 3 can also be found in plant sources such as Linseed Oil.
