Often referred to as the ‘sunshine’ vitamin thanks to the fact that the majority of Vitamin D3 is made in the skin via sunlight, many athletes will be deficient in Vitamin D, particularly during the winter months. An important vitamin for overall wellbeing, Vitamin D deficiencies have been shown to impair muscle recovery and increase the chances of an Upper Respiratory Tract Infection, as well as negatively impact immune system function; all of which could potentially impair performance.

Growing evidence shows that supplementing daily with Vitamin D3 can be beneficial to athletic performance, especially when it comes to preventing winter infections and boosting recovery from muscle-damaging exercise. Vitamin D3 also plays a major role in calcium absorption, making it important in maintaining bone health. 2000IU has been shown to correct deficiencies with no risk of toxicity making it the ideal supplement dose.
