Vitamin D deficiency after supplements

by AG

Can anyone tell me what this means?

I've been taking 2000 IU of vitamin D per day since August 4th due to bone pain and neurologic problems. I suspected a vitamin D deficiency, I was actually tested on 9/13 and my result was 24 ng/ml. I am 40 years old ( if that matters)?

I was retested on 10/12 and my number didn't change.

My results are as follows:

VITAMIN D, 25-HYDROXY 24 30-100 ng/mL
VITAMIN D, 25-HYDROXY, D3 24 ng/mL
VITAMIN D, 25-HYDROXY, D2 <4 ng/mL

Thanks
