Swanson, Keratin, 50 mg, 60 Capsules

Hair, Skin and Nails Support 50 mg Per Capsule Dietary Supplement Keratins are a group of tough, fibrous proteins that help maintain healthy joints and support skin, hair and nails. Keratins deliver an exceptionally high content of the amino acid cysteine, which is in itself an abundant source of sulphur molecules that nourish and strengthen cartilage tissues. When the sulphur molecules from cysteine bond together they form very strong links called "cysteine bridges." These bridges provide vital support for weight-bearing joints. Swanson Premium Brand® Keratin, derived from Tibetan wool, supplies pure, food-grade hydrolysed keratin to nourish healthy connective tissues and promote the health, strength and appearance of skin, hair and nails.
