Can taking Vitamin D3 correct Vitamin D2 deficiency?

Thank you in advance for your time. My doctor tested me for Vitamin D and it and Vitamin D3 both came back at 20 ng/ML (on the borderline with existing reference range). However, my Vitamin D2 came back at <4 ng/ML - MUCH lower than the same 20 ng/ML borderline range also applicable to D2.

So, since D3 has been shown to be up to three times more potent and effective than taking D2 (which is only available from fungi and plant sources), can taking Vitamin D3 correct for my apparently serious Vitamin D2 deficiency...? I can't seem to find that answer anywhere on the internet.

Thank you,

Walter
