Hi IAW, This is RD. I hope you remember me. I can’t find the old thread that I had opened back in spring. I want to ask you a question.
On July 13, my Vit D blood level was 108nmol/mL. <-(result of taking 10k daily for 1 month and 5k daily for 2 months). Doctor said to reduce the dosage.
Between July 16 and August 13, I took 5k WEEKLY.
Between August 27 and October 16, I took 5k BIWEEKLY.
On October 16, I took a blood test. I got 37ng/mL.
I got the results a few days ago.
I’m shocked at how fast the Vit D level decreased within 3 months! Is that normal?
I now weight 101-102lbs. The doctor hasn’t followed up, and I assume he thinks 5k biweekly is good enough. I have no idea how much I should be taking to maintain a level of 50-40ng/mL. 37ng/mL is considered optimal according to the clinic’s chart. How do you calculate the proper amount?
