Scientists track what happens to milk protein in the gut

This study looked at how the body digests and uses milk protein (casein) when it is intact versus when it is broken down (hydrolyzed). Twenty-six healthy adults ate a test meal containing one of these protein forms, and researchers collected blood, urine, and intestinal samples over eight hours. The goal was to understand protein digestion and measure how much protein the body actually absorbs. This was a basic science study, not a test of any treatment or therapy.
