How and where can I purchase the product AMBROTOSE?

The Mannatech Company sells Ambrotose.

If, for some reason, that link does not pop up, just do a search for Mannatech and you should get linked.

Here is another article about Ambrotose - http://chetday.com/glyconutrients.htm

I have used Ambrotose for my son who has Down's Syndrome. A friend of mine, who has a child with Down's Syndrome told me about it and she swore by Ambrotose - said it improved her child's immune system. It did work for my son also, although he has not used it for over a year.

Good luck.
