Where to Buy

A biological compound that occurs in the human body and in some foods, MSM is an excellent dietary source of bioavailable organic sulfur. Doctor’s Best MSM features OptiMSM®, a highly purified form (99.9% pure) of methylsulfonylmethane (MSM). Since the amount of MSM found naturally in living materials is too small to be extracted, the MSM used for dietary supplements is manufactured. The makers of OptiMSM® developed a four-stage process to separate impurities including heavy metals and other contaminants from OptiMSM®. Each batch exceeds the United States Pharmacopeia (USP) monograph standards for MSM, and is validated by testing in independent laboratories.

How does it work?
MSM is an abbreviation for methylsulfonylmethane which is organic sulfur compound. MSM contains two oxygen atoms and two methyl groups bound to a sulfur atom. As it donates its methyl groups, MSM enables important metabolic functions, including energy transduction and enzyme regulation. MSM’s use in joint and skin health stems from its organic sulfur support of the disulfide bonds that reinforce collagen fibers, a property that’s believed to promote connective tissue integrity and resilience. MSM’s immunomodulation may also block cartilage breakdown as it promotes cartilage formation and repair, helping to maintain comfortable flexibility. In soft tissues, MSM’s collagen support and soothing properties may help promote recovery after exercise. In skin, it appears to help fight visible signs of aging while supporting suppleness. As a building block for keratin, MSM may offer additional support for healthy hair and nails.

Why should I take Doctor's Best MSM?
Doctor's Best MSM supplies bioavailable, natural sulfur to help form antioxidants N-acetylcysteine and glutathione and serve as a key structural nutrient in healthy connective tissues. Connective tissues give shape, strength and support to other tissues within the body, notably serving as a framework for healthy skin, tendons, ligaments and bones. As we age, our connective tissues begin to break down. MSM can help assist with these concerns because it helps form, reinforce, and protect connective tissue throughout the body
