Acai (ah-sigh-ee) grows on specific palm trees native to Central and South America. The fruit is about the size of a grape and provides a variety of healthy polyphenols such as the proanthocyanidins found in pine bark and grape seed extract, and the resveratrol associated with red wine, making it a valuable antioxidant. Acai also contains a significant amount of essential fatty acids making it one of few fruits containing omega-3s. Swanson Vitamins now offers Acai Berry Extract 500mg in softgel form 60 softgels for only $4.99. Swanson Vitamins also offers Acai in liquid and capsule form and carries national brands Nutiva, Country Life and Alacer's Emer'gen-C.
