In-home Vitamin D Blood Test
How To Order a Vitamin D Test
The only blood test that can diagnose vitamin D deficiency is a 25-hydroxyvitamin D. Get your levels above 50 ng/ml year-round.
The Vitamin D Council has partnered with ZRT Labs to make a discounted take-home Vitamin D Test Kit that you can order on the Internet. A portion of the proceeds from the sale of each test will be donated to the Vitamin D Council by ZRT to help their mission to end the worldwide epidemic of vitamin D deficiency. The tests will be available to order in either a quantity of one (1) or four (4). Whether you will be testing your entire family or simply retesting yourself, consider the 4 test kit as it is much less expensive per test.

Information
25-hydroxy-vitamin D or 25(OH)D is the circulating form of vitamin D and routinely used to diagnose vitamin D deficiency. The Vitamin D Council recommends 25(OH)D levels be between 50 and 80 ng/mL, year around. These levels assure vitamin D metabolism is normalized. Furthermore, levels of 50-80 ng/mL are “natural” levels, that is, levels normally achieved by people who work in the sun.
Low vitamin D levels have been associated with most of the diseases of civilization but only a few controlled trials show vitamin D prevents disease. Controlled trials showing vitamin D treats diseases are even rarer. Many such studies are currently being conducted to see if vitamin D really does prevent or help treat disease. While you wait for the studies to be finished, what 25(OH)D level do you want to have while you wait, a natural 25(OH)D level, one humans had when they worked in the fresh air and sunshine, or a level that is the result of a civilized indoor lifestyle?
