There are rumors going around that noni juice is a scam and that it has no positive health benefits. However, any scam concerning noni juice is likely related to the watering down of the product and its effectiveness rather than whether or not it is effective in the first place. A true noni juice scam will include the selling of noni juice that is not pure, but has been made from concentrate (also called “reconstituted” juice). Making noni juice concentrate is cheaper, but the process removes vital nutrients from the juice. Noni juice is also ineffective when watered down by being blended with other juices such as apple or grape juice.
