MSM is used as a popular joint health supplement for both humans and animals. Methylsulfonylmethane, more commonly known as MSM, is a chemical used to decrease inflammation and joint pain.
MSM is organosulfur, which is naturally occurring in both plants and animals. Although animals utilize and benefit from sulfur, mammals cannot actually use pure sulfur.
Horses typically obtain sulfur from methionine or cysteine, both amino acids. Although cysteine can be produced internally from methionine, methionine must come from a horse’s food consumption.
Horses suffering from arthritis or poor hoof condition will likely benefit from MSM. Studies have shown MSM can slow the progression of arthritis in horses through cartilage degradation prevention.
Most generic dosages will recommend 2 grams of MSM per 100 kg of body weight (220 lbs). However, many are giving MSM in therapeutic doses for inflammatory issues.
