Our Acai Berries come directly from the Brazilian Amazon! Many other manufacturers grow their berries elsewhere or buy them from other countries where they are mass produced and their effectiveness is significantly decreased. The ORAC Value (Oxygen Radical Absorbance Capacity) is what measures the antioxidant power of the Acai Berry. Most products being sold today have a reduced value, while Acai Ultra Burn boasts one of the most potent ORAC value you can find (70,000!), even more than leading Acai manufacturers!
