Keratin Amino Acids and the Vegetarian Diet
Keratin amino acids are proteins that are extracted from keratin, a fibrous structural protein found in human hair, nails, and the outer layer of skin, as well as in animal products such as feathers, wool, and horns. These amino acids are used mainly in non-food products like cosmetics and supplements, where they are valued for their conditioning and strengthening properties. They are not commonly used as food ingredients due to their animal origin and the availability of plant-based alternatives for similar purposes.
