At present, no USANA products contain Methylsulfonylmethane (MSM).
Methylsulfonylmethane (MSM) – also know as methyl sulfone or dimethylsulfone (DMSO2) – is an odorless breakdown product of dimethyl sulfoxide(DMSO).
Some supplement manufacturers add MSM to their joint health formulas. However, it would be difficult to justify adding this ingredient and price to the Procosa product when research in human clinical trials is still inconclusive.
USANA scientists will continue to monitor the science behind MSM, and any product-related decisions will be based on the best available research.
