Frequently Asked Questions About Mannatech
Are Mannatech glyconutrients effective?
Mannatech's Ambrotose glyconutrient products are based on the concept of glycobiology — the study of sugars in cellular function. While glycobiology is a legitimate scientific field, independent research has not validated the specific health claims made for Mannatech's products. Mannatech paid a $7 million settlement with the Texas AG in 2009 for misleading health claims.
Is Mannatech a legitimate company?
Mannatech is a legitimate publicly traded company (NASDAQ: MTEX) that has been in business since 1993. However, like most MLMs, the income opportunity is challenging and the company has faced scrutiny over health claims. Revenue and associate counts have been declining.
