Mannatech

Mannatech, Incorporated, is a multinational multi-level marketing firm engaged in research, development, and distribution of "glyconutrients," the company's name for blends of plant-sourced saccharides. Mannatech was founded in November 1993 by Samuel L. Caster and is headquartered in Coppell, Texas. It operates in 24 countries, including the United States, Canada, Australia, countries in Asia, Africa, and within the EU. The company's stock is traded on the NASDAQ exchange under the symbol MTEX. Mannatech employs 310 people and sells its products through approximately 229,000 active independent sales associates.

In 2006, Forbes magazine named Mannatech the #5 company on its annual list of the "200 Best Small Companies" and in 2007 Mannatech was ranked 12th in BusinessWeek magazine's 2007 list of America's "Top 100 Hot Growth Small Companies." The scientific validity of Mannatech’s key product Ambratose has been called into question by several researchers, and the company was the focus of a 2005 class action lawsuit (settled in 2008) for alleged violations of the Securities Exchange Act, and a 2007 investigation (settled in 2009) by the Texas attorney general for alleged violations of that state's Deceptive Trade Practices Act.
