Vitamin D Testing


Many athletes are unaware that vitamin D is not officially a vitamin but actually a pro-hormone. Roughly one-third of athletes have insufficient levels of vitamin D with a leading cause being lack of sun exposure. This is common in northern climates where but studies indicate that even athletes in regions with more sunshine are often deficient due to concerns about the ill effects of too much sun.

Sub-optimal vitamin D status is linked to increased risk for acute illness, inflammatory injury, stress fracture, muscle pain/weakness and sub-optimal muscle performance.
