San Diego-based Imagenetix Inc. contends MonaVie engaged in a "scheme and conspiracy" by claiming its products contained Celadrin, an ingredient in remedies marketed by Imagenetix that are designed to ease arthritis pain, joint inflammation and promote joint health. The lawsuit, filed in U.S. District Court in San Diego, names MonaVie founder and president Dallin Larsen, other executives, distributors and employees, and related business entities. Calls seeking comment were not returned by Larsen or attorneys representing Imagenetix. Imagenetix is seeking a jury trial and has asked the court to bar MonaVie from making future claims regarding Celadrin.
