Healthtech Lifestyle’s Ultra Pure MSM is the purest form of dietary methyl sulphonyl methane, available. It is a natural sulphur nutrient found in living organisms. MSM is one of the most bioavailable sources of sulphur. Sulpur from MSM is used in the biosynthesis of the amino acids, methionine and cystine. Cystine plays a vital role in the biosynthesis of other sulphur containing molecules such as coenzyme A and taurine. Methionine and cystine are also required for optimum functioning of the ATP cycle, the fundamental system used by the cells to produce energy.
