Keratin is a group of tough, fibrous proteins that help maintain healthy joints and support the skin, hair, and nails. They provide an extremely high content of the amino acid cysteine, which is a rich source of sulfur molecules that nourish and strengthen cartilage tissues.

When sulfur molecules from cysteine bond together, they form very strong bonds called "cysteine bridges." These bridges provide vital support for weight-bearing joints. Swanson Keratin is derived from Tibetan wool and provides pure, hydrolyzed keratin to nourish healthy connective tissues and promote the health, strength, and appearance of the skin, hair, and nails.

Clinical studies show that:

• Aging is associated with the loss of skin elasticity and the deterioration of connective tissue health.
• The amount of collagen and keratin decreases with age, and taking keratin supplements can slow the deterioration of skin, nail, and hair quality.
• Keratin increases the levels of antioxidant enzymes in connective tissue cells.
• Keratin stimulates skin cells to multiply faster, enhancing connective tissue health.
• A combination of essential vitamins and keratin has been shown to reduce the number of hairs lost due to washing.
• The quality of nails improves with keratin supplements, with reduced breakage and increased strength.
• Skin health improves when women aged 40 to 71 take keratin supplements.
