Biologically, collagen peptides are actually known to support gut health. The amino acids glycine and glutamine help strengthen the lining of the intestinal tract.
However, protein requires a lot of water to metabolize. If consumers take dry collagen powder in a tiny shot of espresso and don’t drink water the rest of the day, their gastrointestinal motility will slow down. It’s simply a matter of the body pulling water from the colon to process the heavy protein load.
