We athletes are driven and work very hard. Our bodies do a great job providing enough Vitamin D naturally, if we spend enough time in the sun. Even if we do, it still may not be enough. Plenty of athletes, especially indoor athletes, have insufficient levels of Vitamin D, even some are at the point of deficiency.
This Vitamin is so crucial to our daily life. It helps us absorb the Calcium in our diet, which is crucial for bones, nerves, muscle growth, immunity, and blood pressure. In addition, it helps reduce colds or flus during the winter, provides better bone integrity and fewer breaks or micro-cracks, faster healing of injuries, and reduced muscle fatigue during and post-workout.
