Vitamin D is sometimes referred to as the "sunshine vitamin" because it is obtained mostly from sun exposure. Despite this, it's estimated that up to 88 percent of the population gets less than the recommended dose of vitamin D.
Vitamin D is so important to human survival that our bodies have evolved to receive it from the sun, which is the only food source that can be found on practically every square inch of the earth, but half of the population is still deficient in vitamin D
"The main benefits of Vitamin D include bone health, cardiovascular health support, and some cognitive benefits, mainly mood-related benefits."
WHY VITAMIN D IS IMPORTANT FOR ATHLETES ?
Vitamin D and athletes is a topic that is constantly being researched. Studies conducted from 1930 to 1950 showed improved performance of Athletes in summer rather than winter, which was the result of UV light exposure. However, as the amount of evidence accumulated, we began to link UV light exposure to increased vitamin D levels.
Athletes who train indoors in the winter, at higher latitudes (north of Atlanta), or who protect their skin with sunscreen, sunglasses, or other methods may have low vitamin D levels.
There are many potential advantages for athletes. Vitamin D has been linked with decreasing inflammation and pain, reduced fracture risk, and an increase in muscle protein and type II muscle fibres.
Vitamin D has a strong relationship with testosterone. Some studies have found a link between sunshine exposure and testosterone levels, with one finding that taking 3,332 IU (international units) of Vitamin D every day for a year resulted in a considerable rise in testosterone (about 20%).
It's worth noting that these increases are often found in persons who go from deficient to sufficient Vitamin D levels — drinking pills to obtain a "supraphysiological" Vitamin D level won't result in Hulk-like testosterone levels. However, there is significant debate about what constitutes a "sufficient" consumption of Vitamin D.
HOW MUCH VITAMIN-D AN ATHLETE NEEDS ?
As per the research, the recommended daily dose of vitamin D is 600 IU (about fifteen micrograms). A mix of dietary intake and vitamin D supplementation is required for athletes who do not get enough sun exposure. Vitamin D levels are unlikely to be maintained just through the use of vitamin D-fortified foods or a multivitamin.
However, the experts advise that you should get medical consultation first before taking vitamin D pills.
