My husband has been taking MSM for his arthritis, since he is allergic to shellfish and so we don't trust the glucosamine to be safe for him (glucosamine is usually derived from shellfish). He says the MSM works wonders on his joints. He has an allergic form of IBD called Eosinophilic Gastroenteritis and the MSM isn't hurting his gut any. MSM is a sulfur supplement. The body converts the sulfur into glucosamine and other necessary sulfur-based substances for healthy connective tissue. You also need Vitamin C. Vitamin C is the conductor, and sulfur is the building block for connective tissue. You might find mineral ascorbates more gentle on the gut than ascorbic acid forms of Vitamin C.
