Jarrow Formulas MSM Sulfur 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.

I used this product since the start of Feb 2017 noted a difference in my knee pain in a couple of days & felt it was a product worth buying but the pain is back so I don't really know if I will be getting it again .i read it somewhere it will make a difference in 12 weeks time for joint pains which I'm yet to see result but for now it's a no.yes it does help with hair skin & nails but that was not my primary motive of taking this.hope it helps but I surely will submit my review in another 2 months time if anything changes.
