Methyl Sulphonyl Methane (MSM)
This is a far less well known joint ingredient compared with glucosamine and chondroitin. However, it is indeed used in some of the more advanced joint products and there is much evidence that it may have benefits in joints.
MSM contains sulphur which is well known as a cross linking agent i.e. it helps to form bridges between molecules thereby giving them extra strength, due to this cross-linking effect. This is not yet totally scientifically proven. However, if this is true, then by strengthening the tissues in the joints such as collagen, in theory this could be beneficial.
Prime Fifty has included MSM in its Joint Care product.
