Maqui berry (Aristotelia chilensis)

Tier 3 — weak evidence · Antioxidant · Metabolic · Eye health

A Chilean-Patagonian berry with the highest known ORAC value among edible fruits, driven by anthocyanins (predominantly delphinidin glycosides). RCTs with a standardised extract (Delphinol/MaquiBright) show improved tear production in dry eye (vs placebo), reduced postprandial blood glucose, and improved oxidative stress markers. Delphinidin content is 3-5x that of blueberries. Effects appear complementary to other berry anthocyanins — not duplicative.

Dose: 60–180 mg standardised extract (Delphinol, ≥35% anthocyanins) daily
