Hydroxyproline - Feed Ingredient

Hydroxyproline is a non-essential amino acid derived from the post-translational modification of proline, primarily found in collagen and other connective tissue proteins. Hydroxyproline is abundant in animal-derived materials such as gelatin and hydrolyzed collagen.

In equine nutrition, hydroxyproline is not typically added as a standalone ingredient but may be present as a component of collagen-based supplements or protein hydrolysates. Its presence is often used as a biochemical marker for collagen content, and its inclusion can support formulations intended to contribute precursors for connective tissue maintenance.
