Creatine Supplementation for Sarcopenia

This trial tests whether creatine supplements can prevent muscle loss in individuals starting GLP-1 agonist therapy, a common weight loss treatment. The study combines creatine with resistance training to determine its effectiveness in maintaining muscle strength during weight loss. Participants will receive either creatine or a placebo (a non-active substance). Ideal candidates for this trial are those beginning GLP-1 therapy who can safely engage in physical activities. As an unphased trial, this study provides a unique opportunity to explore innovative methods for preserving muscle strength during weight loss.

The trial does not specify if you need to stop taking your current medications. However, since it involves starting GLP-1 agonist therapy, you may need to discuss with your doctor how this interacts with your current medications.

Research has shown that creatine is generally safe for most people. Many studies have found that various groups, including older adults, tolerate creatine well. For example, it is often used with strength training and is considered a safe way to help maintain muscle mass as people age.

Creatine supplementation is unique because it uses creatine, a compound naturally found in muscles, to potentially boost muscle strength and mass in people with sarcopenia. Unlike standard treatments like resistance training or protein supplementation, which can be time-consuming and require lifestyle changes, creatine is a simple daily supplement. Researchers are excited about its potential to improve muscle health more conveniently and with fewer lifestyle disruptions, offering a promising alternative for those struggling with this condition.

Research has shown that creatine, which participants in this trial may receive, can help older adults increase muscle strength and size. Studies have found that combining creatine with strength exercises improves muscle performance and increases lean muscle. One review of several studies found that creatine significantly aided activities like moving from sitting to standing. Additionally, evidence suggests that creatine can help prevent age-related muscle loss, known as sarcopenia, and may improve overall physical ability, helping older adults maintain independence.¹²⁴⁶⁷
