Ben Carson's troubling connection

Carson’s interactions with Mannatech, a nutritional-supplement company based in suburban Dallas, date back to 2004, when he was a speaker at the company’s annual conferences, MannaFest and MannaQuest. He also spoke at Mannatech conferences in 2011 and 2013, and spoke about “glyconutrients” in a PBS special as recently as last year.

Mannatech has a long, checkered past, stretching back to its founding more than a decade before Carson began touting the company’s supplements. It was started by businessman Samuel L. Caster in late 1993, mere “months,” the Wall Street Journal later noted, before Congress passed the Dietary Supplement Health and Education Act of 1994, which greatly loosened restrictions on how supplement makers could market their products. Within a few years of its inception, the company was marketing a wide variety of “glyconutrient” products using many of the same tactics previously described in lawsuits against Eagle Shield, Caster’s first company.

In November 2004, the mother of a child with Tay-Sachs disease who died after being treated with Mannatech products filed suit against the company in Los Angeles Superior Court, seeking damages for intentional infliction of emotional distress, negligent misrepresentation, and conspiracy to commit fraud. The suit alleged that the Mannatech sales associate who “treated” the three-year-old had shared naked photos of the boy — provided by his mother as evidence of weight gain, with an understanding that they’d be kept confidential — with hundreds of people at a Mannatech demonstration seminar.
