Because Innvista was sent a Cease and Desist order, even though there was no mention of Mannatech in this section, we have been required to remove this valuable information despite many months of personal research. Apparently, it was the use of the term "glyconutrient" that caused the reaction. You can still buy independent books used as reference material from Amazon.
We recommend that you take the time to visit An Honest Discussion Regarding 'Glyconutrient' Products by Ray Sahelian, M.D., who has a good summary of concerns preceding a long list of questions and answers from readers.
