Our 100% pure, USDA-certified organic, noni juice from Tahiti is not made from a concentrate or a powder. If you are using another brand of noni juice - check the label carefully - statements like puree, reconstituted, concentrate, or purified water added - all mean you are not getting pure straight noni juice. Our certified organic noni juice is 100% pure. That is 30 ml of pure noni juice per fluid ounce. Read the other brand's supplement facts carefully. Many say 20 ml, 10 ml, and even 8 ml of actual noni juice per ounce. That means they are not 100%, as they claim.
