Vitamin D blood test

Vitamin D

Vitamin D status is determined by blood levels of 25-hydroxyvitamin D. Optimal levels of 25-hydroxyvitamin D may be needed in order to promote immune function, bone health and reduce exercise-related inflammation. Low vitamin D is a common deficiency in athletes especially if exposure to natural sunlight is limited; when training in the winter months or when training mostly indoors. In the UK between October and March, synthesis of vitamin D may be almost impossible.
