Vitamin D 25-OH, Total D2, D3-Blood Spot Lab Test Kit
Vitamin D is technically considered a “prohormone” created mostly by the body through skin exposure to sunlight. D vitamins are involved in a number of processes including modulation of the immune system, insulin sensitivity, regulation of hormones and neurotransmitters, and calcium absorption for the skeletal system. Vitamin D may also play a protective role in conditions such as diabetes, heart disease, and some cancers.
What Is Measured?
