Vitamin D Boosts Muscle Energy and May Fight Age-Related Muscle Loss
Dr. Kumar’s Take:
This large-scale study in animals, muscle cells, and older adults gives compelling evidence that vitamin D directly improves muscle energy production by boosting mitochondrial function. It does this through its receptor in muscle cells. Supplementation helped older adults gain muscle and strength, making it a powerful tool for preventing age-related muscle loss and fat gain—also known as sarcopenic obesity. If you’re over 60 and vitamin D deficient, this is a call to check your levels and talk to your doctor about supplementation.
