Collagen Supplement Effects on Quality of Life, Appetite, and Blood Sugar in Overweight and Obese Adults Aged 18 to 65

What this Trial Is About

Researchers are evaluating whether a collagen supplement can improve quality of life, appetite, and blood sugar control in adults aged 18 to 65 who are overweight or obese and have a lower perceived quality of life. The study compares the effects of an 8-day consumption of a collagen peptide supplement versus a placebo in this population, aiming to assess changes in quality of life and glycaemic control. Participants will receive two daily doses of 5 grams of either a hydrolysed bovine collagen peptide supplement or a placebo maltodextrin for 8 days. The study uses a randomized, double-blinded, placebo-controlled, crossover design, where each participant takes both the supplement and placebo in different periods. The treatment phases are followed by assessments, and participants cross over between the supplement and placebo to compare effects within the same individual. During the study, participants will complete questionnaires about their quality of life, appetite, mood, energy, and sleep. They will also wear continuous glucose monitors for up to 22 days to track blood sugar levels and responses after meals. Researchers will measure quality of life scores at baseline and after 8 days, along with post-meal appetite, mood, energy, fatigue, sleep quality, glycaemic variability, and dietary habits. The study includes virtual visits and uses mobile apps for data collection over the trial period.
