DON'T TAKE D2!!!: STOP TAKING Vit D2 immediately. An analysis of 50 studies showed those who take D3 had a 6% decrease in mortality whereas D2 actually increased mortality by 2%!
NO ONE SHOULD TAKE D2!

Please stop D2. Most adults need 5-8000 iu/day of D3 to achieve optimal levels. See

Please share this info with the pharmacist and/or the doc who prescribed D2!!!

Pharmacist is wrong: Take the whole pill. The pills are designed to give the proper dosing and reducing the dose reduces the effectiveness.
