Mannatech is a great and reputable company. I have used the ambrotose many times over the years. I guarantee if people would try it, before they knock it, there would be a different story.
As much as I love this country, I hate that natural products that benefit people with cancer, are quickly attacked.
I suppose its because even if 99 out of 100 were healed, the son/daughter of the one that didn't make it would sue for false advertising. Nothing works 100% of the time and we should rave about products that help more than one person, even if it doesn't help everyone.
There are plenty of crooked companies, but this is not one of them.
