Amazon Thunder Acai Thunder caps with are made with unrefined, organic, pure freeze dried acai pulp powder and nothing else. They are made with organic and kosher ingredients. There are no fillers, flow agents, binders, preservatives, carriers, caffeine, sodium, or sugar. Our freeze dried acai powder is concentrated, potent, and naturally pure acai! We do not use the seed of the acai because it is classified as a filler and dilutes the acai. Please note: beware of claims using the seed. This means it is a less quality diluted version. It is also an excellent source for daily needed healthy Omega, 3, 6 and 9 fatty acids!
