Intestinal Permability

The goal of this clinical trial is to evaluate the effects of 45 days daily administration of three different doses (2.5g, 5g, and 10g) of collagen peptide in healthy adults as compared to a Placebo on intestinal permeability following an acute aspirin challenge. The main question it aims to answer is change from Day 42 to Day 45 following an acute aspirin challenge (NSAID) between three different doses (2.5g, 5g, and 10g) of collagen peptide, respectively as compared to a Placebo on intestinal permeability measured by the urinary lactulose : mannitol ratio (test collected over a period of 5 hours).
