Find out more information on deficiency, supplementation, sun exposure, and how vitamin D relates to your health.

I have been on Vitamin D3 supplements for 8 months following an osteoporosis diagnosis at age 42. My results went from a 39 to a 38! Why would there be a drop now that I have been on supplements (none before). What causes malabsorption of vitamin D?

    Marisa how much Vitamin D do you take a day? Are you saying that before you took any supplements that your level was 39 and is that measured in ng/ml or nmol/l?
