SOLUGEL® collagen peptides - the natural solution for your health

SOLUGEL® collagen peptides - the natural solution for your health


Collagen peptides, which are also known as collagen hydrolysate or hydrolyzed collagen, are a type of highly digestible protein obtained by enzymatic hydrolysis of collagen-rich materials.

Significant number of clinical studies, including PB Leiner’s clinical studies on SOLUGEL® collagen peptides, show the benefits of collagen peptides in relation to the skin, bones and joints, weight management and sports nutrition.

SOLUGEL® contains Type I and Type III collagen proteins

SOLUGEL® mainly contains peptides obtained from Type I and Type III collagen. The most common collagen in the human body is Type I, which is found in connective tissues (skin, bones and tendons).

The presence of Type III collagen strongly depends on age: young skin may contain up to 50% of type III collagen, but as we age this reduces to 5-10%.

Collagen can also be found in eyes, ears, nose cartilage, teeth, lungs, blood vessels, muscles…

Bioactive SOLUGEL® collagen peptides are pure proteins

SOLUGEL® is composed of high-quality collagen peptides obtained from natural animal sources. By breaking down proteins enzymatically into smaller peptides, bioactive SOLUGEL® is obtained and can be easily absorbed by the human body. Indeed, just 15 minutes after ingestion, collagen peptides can already be detected in the blood. The presence of amino acids and peptides in the blood stream reaches a maximum level after 1-2 hours and remains in the blood circulation for as long as 6 hours.*

As a pure protein source, SOLUGEL® collagen peptides consist of a unique combination of amino acids, which include 8 out of 9 amino acids that are essential to our bodies. Unlike other proteins, SOLUGEL® collagen peptides are rich in hydroxyproline, which is an important component of collagen. It is also an excellent source of glycine and proline.
