Insomnia from Taking Vitamin D

by J.M.F

I am hypothyroid, hashimoto F- 46 yrs My vitamin d level is always running low I am taking 4000 iu frequently and I noticed I was not sleeping just dreaming crazy stuff all night for weeks- months, unable to stay asleep and had to urinate a lot. I stopped taking Vitamin D for 2 wks and I was acting normal again and sleeping not dreaming not voiding, but I also started getting my backache and bone pain again. So I started taking vitamin D again for 3 days and on day 3 I am waking up exhausted I am even using a CPAP to help sleep that was working now its not ? Stopping VIT D again. Does this make sense? Is Vitamin D causing this issue?

OK, so first of all there are two likely reasons why you are having these problems with vitamin d- both of which I've already gone over on my site. First one is that your hashimoto's gets better when you take vitamin d due to the decrease in inflammation, thus making you wired. Please read my MANY MANY pages where I've discussed low thyroid and vitamin d, specifically read the ones about Hashimoto's since there is a REASON that you have Hashimoto's, it's not some random thing that you can't fix. It's dietary.

Next, please see the MANY pages that I've written on this, including the Anxiety and Vitamin D, which includes discussion about insomnia and vitamin d, which is the identical problem.

Insomnia with Vitamin D
by: Dana

I really love the detailed information on your site. I do have a question regarding insomnia from Vitamin D. I was tested and have a vitamin D level of 36 and am working to get it up to optimal levels by taking 8,000 IU of vitamin D every morning.

However, since I've started taking the D, I've been getting awful insomnia, sometimes only getting 3 hours of sleep a night, which is very unusual for me. I just can't seem to fall asleep since I started the D and I am getting some night time anxiety as well.

I also take a multivitamin as well as magnesium and have for years for my chronic migraines at 400 mg/day. However, I read on your site that D can uncover magnesium deficiency, so I increased my magnesium two weeks ago to 1,000 mg/day plus regular epsom salt baths while I take the vitamin D. However, this is still not helping and I really have trouble getting to sleep.

I don't want to stop taking the D, but I am desperate for my usual easy sleep. If it helps in your assessment, I am a 29-year-old female. Can you give me any suggestions?

Hi there, I just wanted to add, I also had a similar experience with taking vitamin D. My doctor started me on 50k ui after my test came back with 7 ui. I could only sleep 3-5 hours a night for a week and a half.

She told me that it is unusual to get such a side effect from vitamin D, but I know that each person is different and for me, there was no other changes in my life to cause such sleeplessness.
