About this page: Data is drawn from Nutriofia's structured database of published sources (CoFID, USDA, and published analytical literature). The coverage bar shows what percentage of our 1136 foods have been measured for Proline. This is a research tool — nothing here constitutes medical advice.

About Proline

A non-essential amino acid important for collagen structure and connective tissue; often discussed alongside glycine for collagen formation.

⚠️ Too little

Isolated deficiency is uncommon with adequate dietary protein; issues are more likely in severe undernutrition or certain medical conditions.

🚫 Too much

Excess from food is generally handled by normal metabolism; high-dose single-amino-acid supplements may cause side effects or be inappropriate for some conditions.
