New Research Shows Vitamin D Can Dramatically Increase Athletic Performance

"According to a new review of research, evidence suggests that adequate treatment of vitamin D deficient athletes could dramatically improve their performance. Activated vitamin D is a steroid hormone which regulates more than 1,000 human genes. Recent research indicates that intracellular vitamin D levels in numerous human tissues, including nerve and muscle tissue, are increased when inputs of its substrate, the prehormone vitamin D, are increased."
