Research Summary

Goji berries are rich in antioxidants and have a long tradition as a longevity tonic. Small trials suggest modest effects on antioxidant markers, but evidence is limited and inconsistent, with notable bleeding interaction with warfarin. It is not a treatment for eye disease, diabetes, or any condition.

Evidence levels reflect the currently available scientific literature and may change as new research emerges. Where evidence is limited or conflicting, this is stated plainly.
