Vitamin D deficiency is more common than we realize – especially in geographical climates where there is little sun during the winter season. It’s assumed that over 1/2 the American population may not be getting enough Vitamin D, possibly increasing their risk for osteoporosis, cancer, and other health conditions.
The best way to obtain Vitamin D is via skin exposure to the most natural source of it – the sun. But with longer work hours and lack of sunlight in certain climates, we depend on supplements to fulfill the daily requirement of Vitamin D.
In the past, it’s been challenging to accurately measure the levels of Vitamin D in the body – that is, until now.
Current methods measure levels of thevitamin D metabolite called 25(OH)D, but test methods can sometimes produce inconsistent results. Researchers have developed a Standard Reference Material, a.k.a. SRM 972, to produce more accurate testing results.
