It works. My 25-OHD went from 19 ng/mL to 55 ng/mL with 2000 IU/d. The tablets are small, easy to swallow and the yearly cost is ~$12. Ordering on line takes a moment from home or work. This company always has what I am looking for with a variety of companies represented. I share this sie with my patients.
