Negative claims regarding Shaklee include allegations that it's a pyramid scheme and that information it provides about its products lacks scientific research. Shaklee distributor John Cranney used his association with Shaklee as part of a Ponzi scheme.
Many Shaklee distributors have criticized the company's business model. One, Elizabeth Dopf, specified that Shaklee required her to pay an initial startup cost and order a monthly minimum of Shaklee products. Her superiors encouraged her to recruit more people to the company and to continue purchasing products despite her inventory not selling. The Federal Trade Commission considers these tactics to be consistent with illegal pyramid schemes.
Researchers questioned Shaklee's claims about Vivix, a product designed to slow the aging process. Shaklee's chief executive, Roger Barnett, said that the claims were misinterpreted.
