What Are Tripeptides?
Tripeptides are short chains of exactly three amino acids linked together by peptide bonds. They are among the smallest peptide structures found in nature – and in the world of collagen supplementation, they represent one of the most bioavailable forms available.
Collagen Tripeptides vs. Standard Collagen Peptides
Most hydrolyzed collagen products on the market consist of peptide chains with a molecular weight of around 2,000–5,000 Dalton. Collagen tripeptides, by contrast, are significantly smaller – typically around 300–500 Dalton – consisting of just three amino acids.
The most characteristic tripeptide sequence found in collagen is Gly-X-Y, where Gly stands for glycine and X and Y are often proline or hydroxyproline. This repeating sequence is what gives collagen its unique triple-helix structure.

Amino Acid Profile of Collagen Tripeptides
Collagen tripeptides are particularly rich in:
-
Glycine – the most abundant amino acid in collagen, essential for protein synthesis
-
Proline – a key structural amino acid found throughout connective tissue
-
Hydroxyproline – unique to collagen, plays a role in maintaining the stability of the collagen structure
How Are Collagen Tripeptides Produced?
Collagen tripeptides are produced through an advanced enzymatic hydrolysis process. Unlike standard hydrolyzed collagen, which breaks down collagen into a broad range of peptide sizes, tripeptide production uses specific enzymes to yield a highly defined, ultra-low molecular weight fraction.
The result is a highly soluble, rapidly absorbed form of collagen amino acids.
Absorption
Due to their small size, tripeptides can be absorbed through the intestinal wall more readily than larger peptide chains. Research suggests that Gly-Pro-Hyp – one of the most common collagen tripeptide sequences – can be detected in the bloodstream after oral ingestion.
Note: No health claims are approved under EU Regulation No. 432/2012 for collagen or collagen peptides specifically. The above describes absorption mechanisms as documented in scientific literature, not therapeutic effects.
How to Use Collagen Tripeptides
Collagen tripeptides are typically available in powder form and are tasteless and odorless. They dissolve easily in water, coffee, smoothies, or soups. Typical serving sizes range from 5–10 g per day.

Collagen Tripeptides & Vitamin C
Vitamin C contributes to normal collagen formation for the normal function of bones, cartilage, teeth, gums, skin, and blood vessels.*
For this reason, many people combine collagen supplementation with a source of Vitamin C as part of their daily routine.

Summary
Collagen tripeptides are a highly refined, ultra-low molecular weight form of hydrolyzed collagen. Their unique amino acid composition – rich in glycine, proline, and hydroxyproline – and their small peptide size make them a popular choice among those looking for a premium collagen supplement.
