Focus on Two Amino Acid-Rich Protein Sources
Collagen and glutamine are among the most discussed supplements in health and sports. In this article, we'll look at what both substances are, which amino acids they provide – and why many people use them together.
What is Collagen?
Collagen is the most abundant structural protein in the human body. It makes up about 30% of total body protein and is a component of skin, bones, cartilage, tendons, and ligaments. From the age of 25, the body's own collagen synthesis continuously decreases.
Hydrolyzed collagen (collagen peptides) is well absorbed by the body due to its small molecular size (~2000 Daltons). It primarily provides the amino acids glycine, proline, and hydroxyproline.

What is Glutamine?
Glutamine is an amino acid found in large quantities in the human body. It is considered conditionally essential: under intense exercise or increased stress, the demand can exceed the body's own production. As an amino acid, glutamine is an important building block for proteins and plays a role in nitrogen metabolism.

Amino Acid Profile Comparison
-
Collagen Peptides: rich in glycine, proline, hydroxyproline, alanine, and glutamic acid
-
Glutamine: specifically provides L-glutamine in high concentration
Combined Use in Practice
In sports nutrition, both are often used together – as part of a protein-rich diet and an active lifestyle. Both are tasteless and can be easily stirred into water, coffee, or smoothies.
Dosage Instructions
-
Collagen Peptides: 10–15 g daily
-
Glutamine: 5–10 g daily
The optimal amount varies individually. For questions regarding supplementation, we recommend consulting a doctor or nutritionist.
Note on Vitamin C
Vitamin C contributes to normal collagen formation for the normal function of bones, cartilage, teeth, gums, skin, and blood vessels.*
