Collagen Peptide Q&A

What Are Collagen Peptides?

Wellnex™ Collagen Peptides are derived from collagen, an essential component of healthy bones and skin. Created through enzymatic hydrolysis of gelatin, collagen peptides are highly soluble in water at ambient temperatures, have a low molecular weight, and possess no gelling ability. Collagen peptides contain greater than 90% protein, and are produced from bovine, porcine, or marine sources. 

What makes Collagen Peptides Unique?

Collagen peptides contain 8 of 9 essential amino acids and are uniquely high in proline, glycine and hydroxyproline.  Containing two key di-peptides, hydroxyproline-proline and hydroxyproline-glycine, Wellnex™ Collagen Peptides can be easily absorbed into the body, leading to high bioavailability – supporting skin, bone and joint health.

What are the Differences between Collagen Peptides and Gelatin?

Collagen peptides and gelatin have different functional and physical characteristics. Collagen peptides have a significantly lower molecular weight (100-10,000 Da) than gelatin (100,000 Da) and have no gel strength. A lower molecular weight allows the collagen peptides to be easily absorbed in the digestive tract, delivering the necessary amino acids and  high concentrations of hydroxyproline-proline and hydroxyproline-glycine to enhance skin, joint and bone health. The higher molecular weight of gelatin is more difficult for the body to absorb, but is a useful food ingredient for applications in which gelling is desirable. 

Our collagen peptides provide a variety of formulation benefits. High water-solubility allows product developers to use collagen peptides in a wide variety of applications including bars, powders and beverages – even gummy supplements. Over 90% protein content makes collagen peptides an ideal candidate for protein fortifications and therapeutic foods.  Collagen peptides are also naturally sugar-free, gluten-free, allergen-free and paleo-friendly.
