Keratin Amino Acids and the Rye Free Diet

Keratin amino acids are derived from keratin, a fibrous protein that constitutes the main structural component of hair, nails, and the outer layer of skin in humans and animals. These amino acids are typically extracted from the hooves, feathers, horns, and wool of animals. While they are widely used in cosmetics, hair care products, and some dietary supplements for their strengthening properties, they are not commonly used as ingredients in food products.
