Of importance to athletes is the function of Vitamin D3 as it relates to overall health, bone density, innate immunity, muscle wasting, and exercise-related inflammation and immunity. To train optimally, an athlete should not have any nutrient deficiencies.
The amount of vitamin D that athletes get from their food, even if they take multi-vitamin supplements, is not enough for optimal performance. Recent studies suggest that most westerners do not have optimum levels of Vitamin D because we spend far less time outside. We shut ourselves up in our caves of brick and concrete and spend most of the day inside.
How much activated vitamin D is available to your brain, muscle, and nerves depends on the amount of Vitamin D in your blood. In turn, how much Vitamin D is in your blood depends on how much vitamin D you put in your mouth or how often you expose your skin to sunlight. The Vitamin D Council believes that everyone who wants to be sure that they have enough Vitamin D in their blood for optimal performance should take 5,000 IU's of vitamin D3 in the form of pills every day.
