Eriocitrin is a flavonoid found mainly in lemons and other citrus fruit, particularly concentrated in the peel and pith.

Why it’s used

Taken as part of general antioxidant-focused supplementation, based on its presence in citrus and its structural similarity to other studied flavonoids.

What the evidence says

There is no NIH ODS fact sheet for eriocitrin, and human clinical research is very limited, largely confined to small or preliminary studies. Most available evidence comes from cell and animal research on antioxidant activity, which does not establish an effect in people.

This says what this database holds under these terms. It is not a finding that no research exists.

Context

Available human studies are few, small, and have used varying citrus extract preparations rather than isolated eriocitrin, limiting any conclusion about a specific effective amount.
