I think Mannatech does do some good for many people...you have to be on it for at least six months to allow the glyconutrients to be effective at a cellular level...IF they are effective. Many people seem to swear by them, however I would like to see a trial for it as well. What really irks me about Mannatech is the PRICE!! It's supposed to be a Christian organisation providing help for people with physical illness...that being the case, why dont they live up to the name they have appropriated 'Manna' (which fell from heaven for free), and make it available at more realistic prices!!
