Maqui berries, also known as Chilean Wineberries, are the most potent antioxidant foods available. Native to Patagonia, Chile, these dark purple berries have been used by the Mapuche people for centuries as a medicinal food and beverage. Maqui berries are rich in polyphenols, which are powerful antioxidants that help protect the body from oxidative stress and free radicals. They are also high in vitamins A and C, as well as minerals like iron, calcium, and magnesium.
