Evidence Summary

'Peel powder' is not a single ingredient — it refers to dried, ground fruit or vegetable peels from sources like apple, citrus, pomegranate, onion, or jaboticaba. These peels are rich in dietary fiber, polyphenols (like quercetin and ellagic acid), and antioxidants. Small human studies suggest apple peel powder may modestly improve joint range of motion and antioxidant status after 12 weeks, onion peel powder may improve quercetin absorption compared to extracts, and jaboticaba peel powder may support cognitive performance and appetite regulation — but all findings come from very small or preliminary trials.
