Longevity & AgingNew Treatments Target the Biology Behind Age-Related Muscle Loss
Losing muscle with age can threaten mobility, independence, and survival. This review examines experimental treatments for sarcopenia, the age-related loss of muscle mass and strength. Researchers are targeting several processes, including energy production, cellular cleanup, inflammation, blood supply, and communication between nerves and muscles. Approaches include urolithin A, compounds related to NAD+, drugs that encourage muscle building, and inhibitors of an enzyme called 15-PGDH. The review also highlights trials combining GLP-1 weight loss drugs with treatments intended to preserve muscle. However, the abstract provides no numerical results showing improved strength, fewer falls, or longer life. The authors report that no therapies are currently approved specifically for sarcopenia. This abstract-only summary describes a promising research pipeline, not proven treatment recommendations; several authors disclose commercial interests.
