Keratins are a group of tough, fibrous proteins that help maintain healthy joints and support skin, hair, and nails. Keratins provide an exceptionally high amount of the amino acid cysteine, which is a rich source of sulfur molecules that nourish and strengthen cartilage tissues. When sulfur molecules from cysteine join together, they form very strong connections called "cysteine bridges." These bridges provide essential support for weight-bearing joints. Swanson Premium® Keratin, sourced from Tibetan wool, provides pure, food-grade hydrolyzed keratin to nourish healthy connective tissues and promote the health, strength, and appearance of skin, hair, and nails.
