Vitamin D contributes to the maintenance of normal bones, teeth, muscle function and immune function. Vitamin D also contributes to normal absorption/ utilisation of calcium and phosphorus.

During winter, your body can't make enough vitamin D from sunlight because the sun is too low in the sky. It's also difficult to get enough vitamin D from your food, so Public Health England recommend vitamin D supplementation to maintain immune, bone and muscle health.
