Methylsulfonylmethane (MSM^®) is a natural food found in most plants and in the milk of all mammals. MSM is one of nature’s best sources of dietary sulfur, an important mineral in the synthesis of vitamins (biotin and thiamin), amino acids (methionine and cysteine), and chondroitin sulfates (compounds that assist joint lubrication).

MSM is driven out of all foods, even with moderate processing. At low levels of ingestion MSM functions as a normal dietary ingredient. At higher levels it functions as a pharmaceutically active agent which can be used safely and effectively for a variety of purposes. The body uses MSM to create healthy new cells. Vitamins and amino acids work with MSM during this process. Without proper levels of MSM the body is unable to build good healthy cells.

Veterinarians commonly prescribe MSM for dogs to help promote healthy skin, fur, and nails and to help proper organ and immune system function. It is also commonly prescribed to dogs for Panosteitis (bone inflammation), cruciate and ligament problems, hip and elbow dysplasia and to treat stomach ulcers.

There are a number of methylsulfonylmethane products on the market that are not fit to bear the MSM trademark. The purification of MSM from natural sources is an exacting process that requires the utmost care and precision. Toxins and impurities are a constant danger. In addition to quality and purity testing, ErroPet OptiMSM^® is extensively tested by an independent industry laboratory for both microbiological and heavy metals contamination. ErroPet OptiMSM^® is the finest available, pure and licensed American made MSM.
