Acai is a high potency antioxidant that helps increase vitality and combat free radicals. This superfood is grown along the Amazon River in northern parts of South America in a palm tree native peoples refer to as "the tree of life." This tree produces luscious purple berries full of anthocyanins and polyphenolic compounds. In fact, there are three and a half times more anthocyanins in acai berries than red wine when compared in matching volumes! Recently gaining popularity in fruit smoothies and other beverages, acai berries feature a nearly perfect amino acid complex, trace minerals and more free-radical-fighting power than blueberries, strawberries and cranberries. You can find acai supplements in a variety of forms— extracts, powders, liquids—to suit your needs and preferences.
