Vitamin D is often referred to as �the sunshine vitamin� as it is naturally produced under the skin following exposure to sunlight. During winter periods we can�t make vitamin D from sunlight because the sun is too low in the sky. Because it�s difficult to get enough vitamin D from food, Public Health England recommends supplementation of vitamin D to maintain bone and muscle health.
Vitamin D contributes to the maintenance of normal bones, teeth, muscle function and immune function. Vitamin D also contributes to the normal absorption and utilisation of calcium and phosphorus. The skin cannot create vitamin D if covered in sunscreen or clothing, it is thought that a sun cream with SPF15 will reduce the skin�s ability to synthesize vitamin D by more than 95%. Furthermore, older people and those
with dark skin or those who cover up most of their skin when outdoors are more likely to suffer sub-optimal vitamin D levels. 
Vitamin D2 comes from plant-sourced foods, with mushrooms being a particularly rich source. This vegan presentation of vitamin D has been extracted from UV exposed organic mushrooms.
