In brief

The observational protocol will assess body composition, muscle mass and body-image perception during postoperative weight loss.

Protocol NCT07809152 examines collagen-supplement use after metabolic and bariatric surgery. Participants will be followed over time, comparing supplement users with non-users.

Endpoints include muscle mass, body composition and body image—variables that become especially relevant when weight loss is rapid and preserving lean mass contributes to the quality of the clinical outcome.

The design is not randomised and no results are available. Total diet, protein intake, physical activity, procedure type and self-selection of supplementation may confound the analysis; the registry opens a research question rather than supporting a claim.

Why it matters

Bariatric surgery and GLP‑1 therapies are creating demand for lean-mass preservation strategies, opening design space for protein, creatine and muscle-health ingredients.

Evidence limit

A non-randomised observational study that is still recruiting and has no results. Any associations will not by themselves establish a causal collagen effect.
