DOES IT WORK?
Results vary. Acai berries do have exceptional antioxidant capacity (high ORAC scores). The anthocyanins are real, and some human studies show improved vascular function and lipid profiles. But the weight loss and anti-aging miracle claims? Pure marketing. It's a good antioxidant fruit, similar to blueberries. Not a superfood that will change your life.
