20.06.2022 - Are the collagen peptides not destroyed in the stomach acid?

After oral ingestion, the short-chain collagen peptides are further broken down in the gastric passage by the enzymes present in the stomach (e.g. pepsin). This natural digestive process occurs in the same way in our daily food intake. The reduction process breaks down the already small peptides into even smaller fragments of three or two contiguous as well as individual amino acids. This is necessary for effective absorption of the peptides and amino acids in the small intestine. If the peptides were to enter the small intestine without prior contact with gastric acid, bioavailability would be significantly lower. The digestion process in the stomach is therefore of crucial importance.
