In 1993 a small company, Emprise,  started selling a product called PLUS and then Manapol, using the Network Marketing model.  When they went to expand outside Texas they needed to change their name as a small bank owned that name.

By this time they were already marketing Manapol which was the healing sugar (mannose) from the Aloe Vera Plant.  Since this was food for the body they changed the name and in 1994 Mannatech was born.

They do not use gimmicks like a tooth from a rare animal, a leaf from a tree found in the mountains, a seed of a weed (you get the picture) — in order to sell a product.

For those who want more details about the company, Mannatech, here you go:
