The opinion of independent glycobiologists is that the body cannot digest Ambrotose, as it lacks the enzymes needed.[6] Prominent glycobiologist Ronald Schnaar, PhD of Johns Hopkins School of Medicine[14] told 20/20 in a June 1, 2007 interview, «All of the sugar building blocks that we need in our body are made from the most common foods we eat.»[7]
Hudson Freeze, PhD, leading glycobiologist at the Sanford-Burnham Medical Research Institute[15] said this about glyconutrients: «There are authentic, scientific studies that have looked at people drinking these kinds of materials, and it doesn’t really do anything except increase flatulence.»[7] Freeze is a member of the editorial board of Glycobiology, and Schnaar serves as editor-in-chief.[16] Schnaar and Freeze published a critique of Mannatech’s products in Glycobiology in 2008, describing the lack of published clinical benefits of the «partially purified polydisperse plant polysaccharides» found in «Ambrotose Complex.»[8]
