What is hydroxyproline?

Hydroxyproline is a non-essential amino acid formed from proline and found in high amounts in collagen. It helps stabilize collagen structure in connective tissues.

What are the benefits of hydroxyproline?

As part of collagen peptides or collagen-rich foods, hydroxyproline supports connective tissue structure and may help skin elasticity and joint comfort. It is also involved in collagen formation during tissue repair.

How much hydroxyproline should I take?

Hydroxyproline is typically consumed through collagen supplements rather than as a standalone amino acid. A common supplemental range is about 500–2000 mg per day, depending on the product and goals.

What foods or supplements contain hydroxyproline?

Hydroxyproline is abundant in collagen-containing foods such as bone broth, gelatin, and collagen-rich cuts of meat. It is also present in collagen peptide and collagen hydrolysate supplements.

Is hydroxyproline safe?

For most people, hydroxyproline consumed via collagen foods or supplements is generally well tolerated. People with allergies to the source (for example fish or bovine collagen) or specific medical conditions should consult a clinician.
