Muscle weakness can be caused by a variety of conditions, including aging, disease, inactivity, repetitive use and intensive exercise. A recent study has now linked blood levels of vitamin D blood to muscle weakness and has found that vitamin D supplementation may increase the recovery rate of muscles after intensive exercise.
Participants in the study included 14 healthy and active adults. Participants were instructed to perform intensive exercise with one leg. The other leg acted as the control. Researchers measured bloods levels of vitamin D in both legs before and after the exercise.
They also found that participants with higher levels of vitamin D had lower levels of muscular weakness, immediately after exercise and for up to three days after.
Researchers from The Orthopedic Specialty Hosptial in Utah, The University of Utah, USANA Health Sciences and the LDS Hospital in Utah conducted the study. It was published on April 17, 2013, in the journal Nutrients.
Previous studies have shown vitamin D to be associated with improved kidney health, reductions in the risk of skin cancer, reducing the risk of osteoporosis, combating diabetes, and improving age related eye degeneration.
Vitamin D can be found in milk, fortified cereals, fish, and eggs. As this study shows, your body also processes vitamin D from the sun but it becomes harder for our bodies to process it as we age. A high quality vitamin D supplement is always a good option if you feel that you’re not getting enough through diet and sun.
