Collagen Peptide Drinks Boost GLP-1 and Insulin While Suppressing Ghrelin in Both Normal and Obese People

Oral gelatin hydrolysate increased postprandial GLP-1, insulin, and glucagon while suppressing ghrelin in both normal and obese subjects — collagen peptides trigger satiety hormones beyond their protein content.
