Modern Evidence

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.
