Please read the link I gave you... new studies show D2 is about 87% LESS effective than D3.
Doctors have not received this info yet. Just take more D3 daily to make up the difference. 5000IU may raise you enough daily with D3.
It takes about 3 months to work. And if you are low in magnesium even the D3 may not raise you well. Please look at that thread I gave you carefully...because there are details there to help you. Otherwise you take the D2 and fail and wait longer for D3 change to work for you. It is your choice.
