The Texas Attorney General’s office is investigating and has considered taking legal action against Mannatech, a fast-growing manufacturer of nutritional supplements, whose stock has been one of the year’s sizzlers.

Its lead product, Ambrotose — formally known as a “glyconutritional” — is a type of sugar pill that has been touted for its ability to treat all sorts of ailments, including Down’s Syndrome. The product is sold through company’s 49,000 person direct-sales network.

An Oct. 24 memorandum in response to a public information request says the state’s top cop has “anticipated filing suit against Mannatech” for a number of alleged violations.
