Noni Crystal is made by 100% noni. At first, I'd like to say this is not same as Noni Powder. We use a high-pressure and high-temperature jet to make Noni Crystal by Noni Juice. This is only NTV company can make, and Noni Crystal is only NTV products in the world. This is Sterilized products. No problem, Excellent effect. We always make products by excellent noni. NTV has two medical person who can check thoroughly. They are NTV's investors, and they always help us. If you have more information, DO NOT HESITATE TO CONTACT ME. THANK YOU SO MUCH.
