Summary
This trial tests whether a daily supplement of calcium-HMB plus vitamin D3 can help adults aged 65 to 85 with type 2 diabetes keep their muscle mass and metabolism while starting semaglutide, a common weight-loss and diabetes medication. Participants take the supplement or a placebo for about 6 months. Researchers measure changes in muscle mass, strength, physical function, and resting metabolism to see if the supplement counters the muscle loss that can accompany semaglutide use.
