About epa (eicosapentaenoic acid)

What it is

EPA is one of the two main long-chain omega-3s in fish oil. The body can make small amounts from ALA, but conversion is limited.

Label tip

Add the EPA and DHA lines together to get total EPA + DHA. Prescription EPA-only medicines exist; over-the-counter supplements are not interchangeable with them.
