Dr. Boz wants you to know your vitamin D and IMPROVE it. Our testing kit includes everything you need for TWO tests of Vitamin D. The prepaid shipping label included with the test makes it easy to send your sample to the lab for analysis. Once completed, you will receive easy-to-understand results. If you are in the normal range, congratulations! Use the second kit to retest in several months OR share that second kit with a friend. You may be saving their life. If your vitamin D is not in the normal range, CHANGE. From supplements to sun exposure, you can change your vitamin D levels … and boy OH boy – does it matter! Until now, you were missing access to check your own Vitamin D. Now you can! Take control of your health. Know your levels and start living a more healthy life.
