The effectiveness of collagen supplements for weight loss in adults, with a focus on randomized controlled trials and varying outcomes.
The evidence base since 2010 contains multiple randomized controlled trials (RCTs) and systematic reviews that examine collagen peptides or gelatin for and short-term fat loss, but no large, long‑dura...
Small human studies and animal experiments suggest gelatin and some collagen formulations can increase satiety hormones (like GLP‑1) or reduce hunger in the short term, but the clinical picture is mix...
A small but growing set of randomized trials has directly tested collagen or gelatin supplements for effects on body weight or body composition in adults, with several 12‑week randomized, double‑blind...
Clinical trials and human feeding studies show that gelatin and some collagen formulations can increase short‑term feelings of fullness and alter appetite hormones like GLP‑1, leptin and ghrelin in so...
Hydrolyzed collagen, collagen peptides and gelatin have been widely tested in clinical trials — but almost none of the registered or published randomized trials were designed primarily to test oral co...
Controlled human evidence that gelatin or collagen supplements reduce appetite or produce meaningful weight loss is mixed and limited: small randomized trials show occasional signals (changes in satie...
Clinical trials and reviews give mixed, limited support that gelatin or collagen can increase satiety or modestly aid weight loss: acute studies show some hormonal and subjective satiety effects for g...
Existing clinical trials have tested gelatin, hydrolyzed collagen peptides, and native (undenatured) collagen for effects on body composition and satiety, but almost all human randomized trials are sh...
