D2 just does not work well in humans. I have links
explaining why. You can find D2 new findings on
Google too. D3 is not approved by FDA as a drug..
it is an OTC supplement instead.

I cannot go into detail now but this information is
available on NeuroTalk.

5000IU of OTC D3 daily should get you in range within
3months. It is very inexpensive too.

There is not much VitD in food.
You need 1000IU D3 for every ten points to raise.

Humans are designed to make D from sunlight. And
BTW VitD is not a vitamin... It is hormone.
