|University of Manchester researchers have recently found that vitamin D levels are positively associated with muscle strength in adolescent girls. While vitamin D is often thought of in its capacity as a preventative measure against bone disease, this study is an example of some of the proactive properties of the vitamin.
“We know vitamin D deficiency can weaken the muscular and skeletal systems, but until now, little was known about the relationship of vitamin D with muscle power and force,” said Dr. Kate Ward, primary author of the study which appeared in the Journal of Clinical Endocrinology and Metabolism.
Vitamin D has become a hot topic in the wintry months, as a lack of sunlight for many Americans leads to a deficiency of vitamin D in the body. Many times, a vitamin D deficiency can go unnoticed until it is too late. "Vitamin D affects the various ways muscles work and we've seen from this study that there may be no visible symptoms of vitamin D deficiency," said Dr. Ward. Often the outcome of vitamin D deficiency results in skeletal issues much later in life, such as osteoporosis. Only now, with studies like this one, are we beginning to see the many other issues a lack of this essential vitamin may raise.
