Benefits
A marine omega-3 fatty acid that supports heart health and helps regulate the body's normal inflammatory response.
How much you need
No Dietary Reference Intake — no RDA and no AI — has been established for Omega-3 EPA. It's included in Tavita's library for the reasons described above, even though NASEM hasn't set a numeric daily target for it.
Upper limit
No tolerable upper limit has been established for Omega-3 EPA. That's consistent with there being no standard daily target for it in either direction yet.

Body systems & goals
Body systems it supports
- Heart — Your heart beats around a hundred thousand times a day, and these nutrients support the rhythm and the healthy blood flow behind it. They help your body maintain circulation you don't have to think about. (established evidence)
- Liver — Your liver is the body's processing hub, handling everything you eat, drink, and metabolize. A balanced spread of these nutrients supports the everyday work it does to keep you steady. (emerging evidence)
- Joints — Your joints let you move freely, cushioned by cartilage and connective tissue that rely on these nutrients. Supporting them helps your body maintain comfortable, easy movement. (emerging evidence)
- Brain — Your brain runs on a steady supply of these nutrients to think, focus, and hold a mood. Keeping them topped up supports the mental clarity that's often the first thing to fade when you're worn down. (emerging evidence)
- Lungs — The tissue lining your airways renews itself constantly. When you're run down or recovering, these nutrients support that quiet upkeep. (emerging evidence)
- Skin — Skin is your body's largest organ and it rebuilds itself constantly. These nutrients support the collagen-making and repair work that keeps skin looking clear and feeling calm. (emerging evidence)

How Tavita handles this
Tavita logs Omega-3 EPA from both the food you eat and the supplements you take, adding both into one running daily total. There's no established daily target or upper limit for Omega-3 EPA yet, so Tavita shows your intake plainly rather than manufacturing a percentage against a number NASEM hasn't set.
