Jarrow Formulas MSM is an organic source of bioavailable sulfur. Sulfur is an antioxidant mineral found in major structural tissues of the body such as cartilage. The sulfur from MSM is used to produce glycosaminoglycans (or mucopolysaccharides) present in proteoglycans, such as chondroitin sulfate, dermatan sulfate and hyaluronic acid.* These sulfur-containing glycosaminoglycans are found in high concentrations in connective tissues, including joint cartilage, skin and collagen.Dietary ConsiderationsWheat FreeDairy/ Milk FreeGluten FreeVegetarianSoy FreeVeganEgg FreeShellfish FreeNon-GMOFish FreeTree Nut FreePeanut FreeSuggested UseTake 1 capsule 1 to 3 times per day or as directed by your qualified healthcare professional.Serving Size:1 Vegetable CapsuleServings Per Container:200Amount Per ServingOptiMSM Methyl-Sulfonyl-Methane (MSM)1000 mgOther Ingredients:Magnesium stearate (vegetable source), capsule consists of hydroxypropylmethylcelluloseWarningsIf you have a medical condition, are pregnant, lactating, trying to conceive, under the age of 18, or taking medications, consult your healthcare professional before using this product.
