Vitamin D, also known as the ‘sunshine vitamin’, is a hormone that’s produced when skin is exposed to sunlight and is used by every cell in your body to assist with the absorption of calcium, phosphate and magnesium. It’s essential for our bones, muscles and regulating our immune system for overall health and wellbeing. Vitamin D is manufactured during sunlight exposure directly onto the skin and can also be sourced from eggs, wild mushrooms and nutritional supplements. Note that commercial mushrooms are usually grown in the dark, so have negligible vitamin D. With vitamin D obtained from sunshine, we cannot overdose on it, as we can from supplements.
