Vitamin D For Healthy Athletes

Vitamin D For Healthy Athletes It's estimated that three fourths of American teenagers and adults may be vitamin D deficient. What does this mean for team sports athletes? Consider the implications of a study published in the International Journal of Sports Nutrition and Exercise Metabolism that tracked 45 male and female college swimmers for six months.

At the beginning of the study period, all athletes had adequate vitamin D levels. During the 6-month trial, half of these athletes supplemented their diet with 4,000 IU of vitamin D while the rest received a placebo. 13% of study subjects were vitamin D deficient at the half-way point, and deficiency increased to 16% of participants by the conclusion. Researchers determined that 77% of injuries occurred in vitamin D deficient athletes.

True Strength Moment: Vitamin D is known as the sunshine vitamin because it can be synthesized through the skin from sunlight. It's found in very few foods, so vitamin D supplementation can help very active adults maintain adequate levels during the winter months when there's a lack of sunshine in northern regions.
