High Vitamin D Intake Might Improve Athletic Performance

January 14, 2017 - Admin

High intake of vitamin D might increase muscle function, decrease recovering time after exercise, promote strength and power and increase testosterone levels— according to a literature review by researchers from Simon Fraser University in Canada. Vitamin D receptors are located in almost every tissue in the body, and the vitamin is involved in controlling the activities of more than 900 genes. Doses up to 4,000-5,000 international units per day combined with vitamin K could improve athletic performance. High doses of vitamin D have negative side effects and increase the risk of premature death. (Journal International Society Sports Nutrition, 12:33, 2015)
