Andrew Lessman's MSM 500 delivers a pure, concentrated source of organic sulfur. MSM is short for Methyl-Sulfonyl-Methane and despite its long name, it is actually a small, easily absorbed molecule that is ideally built around a central sulfur molecule. Sulfur is perhaps the most overlooked essential nutrient necessary for maintaining the health of our hair, skin, nails and joints. Sulfur plays an essential structural and functional role in joint and connective tissue (cartilage, ligaments and tendons) and it is also essential to the creation of the proteins (elastin, keratin and collagen) that comprise our hair, skin and nails. Like so many essential nutrients, sulfur is removed by modern food processing, making supplementation an important consideration for joint health, as well as the attractive appearance of our hair, skin and nails. Our MSM 500 is a highly concentrated source of the organic sulfur required for the structure and function of some of the most challenged tissues in our body – our hair, skin, nails and joints.Ethical Eco-friendly.
