I don’t see why someone would take D2 instead of D3 unless they were a vegan and concerned about where the Vitamin D comes from. From what I’ve read, D3 is better at raising your level.
Thank you. The D2 by prescription, at 50,000 I.U. per week appeared to raise my D levels faster than the 5,000 D3 daily OTC supplement. I was wondering if anyone else had this experience.
