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 pheromone vitamin D, are increased.

Vitamin D also increases the size and number of fast twitch muscle fibers. Most cross-sectional and randomized controlled studies show that vitamin D levels are directly associated with musculoskeletal performance.
