Vitamin D is a nutrient that is critical to many bodily functions. It is beneficial for supporting bone health, immune wellness, cardiovascular function and cellular metabolism. Vitamin D is essential for life; it regulates calcium homeostasis in the body, plays a role in most organs and systems of the body and acts as a ‘molecular switch’ by influencing the expression of multiple genes.

 

Studies have shown that Vitamin D levels are often low in the general population. Whilst some Vitamin D is obtained from the diet, the major source for replenishment is exposure of the skin to sunlight. However a number of factors may hinder this process, i.e. covering the skin with sunscreen, also sun exposure not possible all year round.
