Acai berries are more than a rich source of antioxidants. Acai berries contain high levels of anthocyanins. These protect foods from harmful free radicals that develop as a result of exposure to UV light and the process of metabolism. The  Anthocyanins in Acai berries not only help to conserve antioxidant levels in foods, but they continue to do this in the body after they are eaten. The benefits of drinking a daily glass of red wine for its anthocyanin content are put in the shade by the amazing Acai berry, which actually contains anything from 10 to 30 times more anthocyanins.

The açaí palm or aqai (Euterpe oleracea) is a species of palm tree in the genus Euterpe cultivated for their fruit and superior hearts of palm. Its name comes from the European adaptation of the Tupian word ïwasa'i, '[fruit that] cries or expels water'. Global demand for the fruit has expanded rapidly in recent years, and Acai is now cultivated for that purpose primarily.

Recently, the açaí berry has been marketed as a dietary supplement. Companies sell açaí berry products in the form of tablets, juice, smoothies, instant drink powders, and whole fruit.

Marketers of these products, such as Monarch Health Sciences, parent company of MonaVie, make claims that açaí provides increased energy levels, improved sexual performance, improved digestion, detoxification, high fiber content, improved skin appearance, improved heart health, improved sleep, and reduction of cholesterol levels. Quackwatch noted that "Acai juice has only middling levels of antioxidants—less than that of Concord grape, blueberry, and black cherry juices, but more than cranberry, orange, and apple juices." Furthermore, the extent to which antioxidants by themselves promote health is a matter of some debate. No credible evidence suggests antioxidants promote weight loss. According to the Washington, D.C. based Center for Science in the Public Interest (CSPI) thousands of consumers have had trouble stopping recurrent charges on their credit cards when they cancel free trials of açai-based products. Even web sites purporting to warn about açai-related scams are themselves perpetrating scams. Apparently false claims include reversal of diabetes and other chronic illnesses, as well as expanding size of the penis and increasing men's sexual virility and sexual attractiveness to women.
