Açaí is one of nature’s richest sources of anthocyanins—a type of bioflavonoid. Anthocyanins make up the purple, red, and blue-black pigments found within certain berries, fruits, plants, and flowers. The fruit of açaí also contains protein, fiber, enzymes, vitamin E, amino acids, minerals (potassium, calcium, magnesium, phosphorus, copper, manganese, zinc, and boron), phytosterols, and beneficial fatty acids.
