What is Cystine?
Cystine is a sulfur-containing amino acid formed by the oxidation of two cysteine molecules linked by a disulfide bond. It is classified as a non-essential amino acid and is commonly used in dietary supplements. Cystine is frequently included in formulations marketed for beauty-related products, such as those targeting hair, skin, and nail care. Its role in these supplements typically relates to its structural properties and presence in keratin. It is often combined with other amino acids and nutrients in complex blends designed for cosmetic applications.
