Collagen Peptides From Gelatin Are Absorbed Into Human Blood After Oral Ingestion
Hydroxyproline-containing peptides from oral gelatin/collagen hydrolysate were detected in human blood, proving oral collagen peptides survive digestion and reach the bloodstream — validating collagen supplement bioavailability.
Quick Facts
What This Study Found
Hydroxyproline-containing di- and tripeptides from orally ingested gelatin hydrolysate were detected in human plasma, with food-grade collagen hydrolysate producing higher peptide blood levels than gelatin — confirming oral collagen peptide bioavailability.
