Glyconutients are not made of sugar. They are polysaccharides that your body needs for proper cell function. If you go to glycoscience.org, it explains what they are and how they work much better than I can. They don't interfere with any medication and are safe for everybody, even children. My kids take the Ambrotose vitamins. My aunt, who has multiple myeloma, is also diabetic, and she takes the Ambrotose, as well. I have had blood sugar problems and tachacardia (irregular or elevated heartbeat)in the past, and the glyconutrients actually have helped control those issues. They are equivalent to eating massive amounts of low glycemic fruits and vegetable, roots and plants. Doctors may tell you that they will interfere with medications, but they tell you that because they don't really know and they don't want to be liable. They've also told me not to take them before any procedures or surgeries I've had in the past, but I did anyway. My surgeries were more than successful, and it's never interfered with my medications. I'm actually on about the lowest dose of medication that a transplant patient can take. Kim
