The acai palm is a tree native to Central and South America. Acai berries (and the juice from the berries) are high in antioxidants and have become a popular ingredient in a variety of health drinks, foods, and supplements. The acai berry is claimed to provide numerous different health benefits.
The acai berry contains a variety of different substances and compounds, such as proteins, lipids, vitamins, minerals and nutrients, anthrocyanins, and flavonoids. It is a rich source of antioxidants.
There is also some evidence that acai berry may inhibit cyclooxygenase (COX-1 and COX-2) enzymes, at least in "test tube" studies. Theoretically, this could be how it might work for
arthritis or other inflammatory conditions.
Despite the widespread hype, there is little scientific evidence to suggest that acai products really work in humans.
"Test tube" studies definitely suggest that the fruit shows significant promise due to potent antioxidant activity, but test tube studies do not always reflect how a substance will affect humans
(see Acai Berry Research for more information).
