Question:
Answer:

EPA (eicosapentaenoic acid) and DHA (docosahexaenoic acid) are the names of two long-chained fatty acids which are found almost exclusively in marine fat. This is also why they are usually called marine Omega-3 fatty acids.

Omega-3 also exists in plants, but these fatty acids differ from EPA and DHA in that they are shorter.

The body needs EPA and DHA for several important functions, both as building blocks and signal substances. A considerable amount of the brain consists of DHA, and EPA and DHA are important for cardiac health.

Plant-derived Omega-3 can to a certain degree be converted to EPA and DHA in the body, but a considerably higher intake is necessary in order to achieve optimal levels in the tissue.
