After reading the book, I had to try Noni juice to see if it would help me with some health issues I was experiencing. Unfortunately, after 6 months, I still didn't see or feel any results, which is why I no longer need the book. I was recommended isotonic OPCs and found they relieved not only my complaints, but have since helped many others. Noni is a smelly little berry that tastes awful and did nothing for me. I'll stick with the OPCs thanks!
