Hi,I am Dr. Shanthi.E (General & Family Physician). I will be looking into your question and guiding you through the process. Please write your question below.
I have had a Vit D reading for the last several years in the 18 range. Two months ago I took 50,000 IU Vit D each week for 4 weeks. Then I took 1X2000 IU daily for 1 month. My blood test today registered 21. Why am I not absorbing Vit D ? Is there something abnormally wrong?
