4-Hydroxyproline (hydroxyproline)

FDA-approved active Quality 6/100

4-Hydroxyproline, also known as hydroxyproline, is a non-standard amino acid that plays a crucial role in collagen synthesis. It is a small molecule that works by incorporating into collagen chains, which are essential for skin, bone, and connective tissue health. However, as a non-drug entity, it does not have a specific target or approved indications. Hydroxyproline is not a patented or FDA-approved pharmaceutical, but rather a naturally occurring compound found in collagen. It is not associated with any specific commercial status or safety considerations.
