This study found that sepsis patients often develop persistent muscle weakness even after recovery, which is linked to damaged cellular powerhouses (mitochondria) in muscle tissue. Researchers discovered that NMN supplementation helped preserve muscle strength in septic mice by protecting these mitochondria. The treatment worked by supporting a key protein called SIRT3 that helps maintain healthy muscle cell energy production.

NMN supplementation preserved muscle strength during sepsis by protecting mitochondrial function, suggesting potential for preventing muscle weakness in critically ill patients.
