Supplement with D2 or D3?

My rheumatologist prescribed 50,000 IU capsules to be taken 1 per week for 5 weeks, in response to my Vitamin D levels of 11 ng/ml. She prescribed ergocalciferol.

I went to see her because I had been having muscle cramps that woke me 2-3 X/night, and also occurred several times during the day. I have taken the last of the capsules, and the cramping has significantly decreased both in frequency and intensity.

However, everything I am reading says that Vitamin D deficiency should be treated with vitamin D3 rather than vitamin D 2.

I do not know if the Vitamin D assay that was done included both D2 and D3 levels. I am scheduled for a follow-up visit next month.


Should I ask her to recommend or prescribe a vitamin D3 supplement?

As of now she is my hero, because no one else has been able to help resolve my muscle cramps problem.
