Promotes joint, skin, hair, and nail health
Keratins are a group of strong fibrous proteins that help maintain joint health and support skin, hair, and nails. Keratins provide an extremely high content of the amino acid cysteine, which is itself a rich source of sulfur molecules that nourish and strengthen cartilage tissues. When sulfur molecules from cysteine bond together, they form very strong connections known as 'cysteine bridges'. These bridges provide vital support.
