Vitamin D is an important nutrient for runners, and here’s what you should know it’s health impacts and dietary sources.

Vitamin D plays an important role in the fitness of runners and it can play an important role in increasing your performance and improving your immune function.
The Science Behind Vitamin D
Vitamin D is a fat-soluble vitamin that be be obtained from food, supplements and sun exposure. The liver and kidneys then help to cover the vitamin to its active form, which is most known for its regulation of calcium and promotion of bone mineralisation.
However, vitamin D also influences cell growth and neuromuscular and immune function.
So…. how can vitamin D aid in our running performance?

Quite a lot of research has connected deficient vitamin D levels to bone-stress injuries. It is recommended while training for a marathon to increase your levels of vitamin D to avoid injuries.

Chocolate Milk and Other Food Sources
There are very few food sources that contain natural vitamin D. Fatty fish such as salmon, swordfish, trout and mackerel contain it, as do egg yolks and mushrooms. Canned Tuna is also a great source too!
Sun Exposure
Sun exposure is one of the best ways to get natural vitamin D into your body. However this comes with a set of variables that may affect you, such as skin type, depending on your skin type, you may need to protect your skin from the potentially harmful rays of the sun, however this may decrease the amount of vitamin D you absorb. Cloud coverage, time of day, location and season also have an impact on this.
