For a hydroxy vit d deficiency- should i take vit d2 or vit d3 supplements? and what dose should i take to improve it?

D3, 5000-8000 IU day: In vitamin d deficiency many physicians prefer a daily dose of 5, 000-8, 000 iu of vitamin d3 rather than 50, 000 iu once weekly due to poor absorption of a single dose of 50, 000 iu. Once 25 hydroxy vitamin d levels reach 60 - 80, the daily dose (5, 000-8, 000) is usually cut in half and the patient followed to ensure the new dose is able to maintain therapeutic vitamin d levels.

D3: D3 is more bioavailable than d2. 5000 iu daily.
