What is Vitamin D?
According to the Harvard T.H. Chan School of Public Health, vitamin D is a fat-soluble vitamin that helps the body to absorb and retain calcium and phosphorus. Vitamin D is so important that we need it to build and maintain healthy bones. Furthermore, laboratory studies have shown that vitamin D can regulate many other cellular functions in our body. Such as minimizing cancer growth, fighting infection, and diminishing inflammation.
Over the past years, approximately 1 billion people are deficient in vitamin D, and this will continue to grow, according to the National Library of Medicine. In addition, 36% to 57% of the American population lack this vitamin. In relation to athletes, vitamin D deficiencies are mostly found in dancers, swimmers, volleyball players, weightlifters, and runners.
Risk Factors for Vitamin D Deficiency:
Many adults do not get enough vitamin D due to less exposure to the sun or having trouble absorbing vitamin D. Especially in the winter or athletes that play indoor sports. Lack of vitamin D can lead to many health issues. According to Mayo Clinic, vitamin D deficiency can lead to soft bones (osteomalacia), weak bones (osteoporosis), bone disorders, and may be associated with cognitive decline.
