Multiple Sclerosis and a Vitamin D , 25 Hydroxy level of 9 ng/mL
(Richland, MI USA)
I have multiple sclerosis and recently asked my doctor to check my Vitamin D level because I read about a possible link between Vitamin D and MS. A Vitamin D 25 hydroxy test was performed to accurately quantify the sum of Vitamin D3 25 hydroxy and Vitamin D2 25 hydroxy.
My result (ref range 30-80) was 9 ng/mL. My doctor sent me a letter saying this was very low and to begin taking 2000-3000 units/day of Vitamin D and do a recheck in 3 months.
I am now taking a Vitamin D3 supplement, however, I'm questioning if that dose is aggressive enough? Does the MS have impact on my dosing? I want to sleep all the time; is this potentially because of the low Vitamin D? How serious is a level of 9 ng/mL?
Thank you for your help.
