This joint supplement delivers methylsulfonylmethane (MSM) in a pelleted form blended with stabilized rice bran to improve taste acceptance and make daily feeding simpler than loose powder. Each dose is formulated to provide a measured amount of MSM, a source of bioavailable sulfur, to support joint function in horses. The pellets can be top-dressed onto grain or mixed into a normal ration and may be given during or after mealtime. A loading period of higher daily intake is followed by a lower daily maintenance amount once the loading week is complete. The product is intended for animal use only and should be kept away from children and other animals. It is packaged in a tub for use in barn or stable settings.
