Overview
The CONCRET-SARCOPA trial is a 12-week, double-blind, randomized controlled study designed to evaluate the efficacy of creatine HCl supplementation in older adults with sarcopenia. The trial investigates whether daily creatine HCl improves body composition, enhances functional muscle and cognitive performance, and favorably alters key blood biomarkers associated with muscle health and metabolic status. Additionally, the study assesses changes in tissue creatine levels using non-invasive and biochemical methods to clarify mechanistic responses to supplementation. Findings from this trial will provide critical evidence on the therapeutic potential of creatine HCl as a targeted nutritional strategy for managing sarcopenia in the geriatric population.
