Vitamin D for stronger muscles

According to a study published in Medicine & Science in Sports & Exercise, sufficient vitamin D may help muscle mass loss associated with aging.

Researchers examined more than 400 adults and found that participants with increased vitamin D levels had greater muscle strength in both arms and legs, even after controlling for age, gender, BMI, and season of vitamin D measurement.

Vitamin D levels were more strongly associated with arm strength, although they were associated with leg strength as well.

“The results of this study indicate that vitamin D may be a viable treatment for muscle strength loss in adults. This is a key area of aging research since people lose strength as they age, but maintaining muscle strength helps prevent falls and fractures, and preserves the ability to live independently,” said lead author, Paul D. Thompson, M.D., FACSM.

The authors call for further research to learn more about the vitamin D, muscle strength association.
