Why Test Your Vitamin D Levels?
Research shows that Vitamin D is important for general health and wellness. Vitamin D is produced in the skin via exposure to the sun, but in the UK more than 50% of the population don’t make enough Vitamin D, and in the winter the Government advises that we should all supplement with Vitamin D because most of us are deficient, when sunlight levels are so weak that we cannot produce Vitamin D even when outside. Even in the summer, Vitamin D deficiency is common due to the use of sunscreen and spending a lot of time indoors.
Signs You May Have a Vitamin D Deficiency

Why do we Need Vitamin D?
Where do I Get Vitamin D?
How Much Vitamin D do I Need?
The body needs at least 4,000 IU/day in order to maintain a healthy concentration of Vitamin D in the blood. Because most of us don’t get enough sun exposure, the little Vitamin D we get this way, plus food and fortified food sources, totals no more than about 2,000 IU/day. So, in order to meet the body’s need for at least 4,000 IU/day, most adults should take supplements.
