University of California Berkeley Wellness Letter and MLMWatch commented on the unreliability of Juice Plus testimonials provided by former professional athlete O. J. Simpson. Simpson, known commonly as "O. J." and "The Juice", signed a multi-year six-figure contract with NSA in January 1994 and became an official celebrity endorser of Juice Plus. In March 1994, Simpson was videotaped telling 4,000 Juice Plus distributors at a sales meeting that the product had cured his arthritis, improved his golf game, and freed him from using anti-arthritic drugs. However, regarding the murder of his ex-wife Nicole Brown Simpson and her friend, Ronald Goldman, for which Simpson was tried and acquitted, Simpson claimed in his defence that he was too incapacitated by arthritis to have committed the murders and had continued to take the anti-inflammatory drug sulfasalazine. As a result of the controversy surrounding Simpson, NSA cancelled his endorsement contract and stopped using the Simpson videotape to promote Juice Plus.
