A member asked:
I have vit d deficiency and was prescribed vit d2 1.25 mg (50, 000). what is the difference between v it d2 and vit d3?
A doctor has provided 1 answer
D2 vs D3: If you have a choice, use the d3 rather than the d2. The d3 is a more useful form for the human body. There are very technical differences between these compounds. Note that I am not using the term 'more natural' since these compounds are often both made synthetically.
