To ensure bioactivity, it is essential to have exceptional bioavailability in the target tissues. Peptan has been shown to have high digestibility and excellent absorption. More than 90% of Peptan is digested and available as small peptides in the blood stream within one hour. From the blood the peptides (containing hydroxyproline, a unique amino acid) are transported into the target tissues, e.g. skin, bones and cartilage, where they act as building blocks for the local cells and help boost the production of new collagen fibers.
In a model1 imitating digestion in the human gastro-intestinal tract, different types of Peptan were tested for their digestibility.
In an in vivo study2, the appearance of free and peptide-bound hydroxyproline was measured in the blood at different time points over 24h after ingestion of Peptan
These results are in line with reports from other studies showing that collagen peptides are absorped in high concentration into the blood3,4.
Several in vivo studies5 demonstrate, by the use of labeled collagen peptides that when present in the blood, the peptides will reach the connective tissues.
