Surg - did your doc test your blood levels, or just quote you a standard line about supplements?

I've got ridiculously low levels of vit D and iron (and previously B12, but I got that up to normal after years of heavy supplementation). So far, every time I get blood checks for the vit D and iron the doc tells me to add MORE. Those three are my only problematic levels, so that's all I supplement.

I take huge doses of B12, vit D, and iron every day.

Thank goodness for Costco...
