"Raw Living's MSM Our MSM is derived from plants such as flaxseeds, and not from petroleum sources. Sulphur is known as the “beauty mineral” because it is great for glowing skin, shiny hair, and strong nails. There are two methods used for purifying MSM, crystallisation and distillation. Crystallisation is cheaper and risks impurities. Our MSM is purified by distillation, 100% pure. No fillers, binders, additives or flow agents. Most MSM is fossil based, and crystallized, which will not give as pure a product (as distillation)"
