Hi Lesley,
I can't say I have had issues with that, but I hope it works out for you. Your provider may just want to get what is a therapeutic level for you. Good luck!

Someone asked about vitamin D3. I was taking for a couple of days extra D3 more than the usual 3000 IU and I had shortness of breath and joint. I found it was caused by too much vitamin D3. I went back to the 3000 IU and am fine

Thank you. They tried me on Invita D3 but I was allergic to the glycerine in the meds. I bought the Vitabiotics instead.

Hi Lesley,
That is good for your provider to know. Try to have a good day!

I only take the prescribed amount of vitamin D.
