The quality of Collagen

Duval Collagen is made exclusively from marine collagen peptides and food-grade bovine collagen. The fish is sustainably and wild-caught in European waters, ensuring a pure, high-quality source. Combining bovine and fish collagen creates a peptide profile perfectly suited to the needs of tendons, ligaments, and connective tissue. The product is completely free of sugar, byproducts, flavors, and fillers, and is mixed in small batches for consistent quality. Each serving delivers the precise, pure building blocks that the body can utilize directly.

Horse tendons and ligaments consist of approximately 90% collagen. We choose collagen because this substance no longer needs to be metabolized by the body for absorption. This is in contrast to glucosamine or chondroitin, which must first be metabolized by the body before they can be absorbed. During the conversion of these substances, a large portion is often lost, meaning the actual absorption is lower than with collagen.
