Vitamin ADK supplement making me feel worse?

Hey guys I have lower vitamin D levels. I originally started at 32ng/mL and have got it to 38ng/mL a couple of months ago. I noticed whenever I take vitamin D and this supplement with 5,000 IU’s it seems I feel worse? I also have reactivated EBV for a year and it seems that this kinda flares me up with fatigue and gives me joint pain and stuff… should I go down to like 1 or 2,000 IU’s a day? I’m going to get my levels checked again to see.
