Toxic Vitamin D level?

by Lin
(Nebraska)

I had my Vitamin D level checked in August, where it was around 40. I got a fibromyalgia relapse and the doctor told me to start taking 10,000 to 20,000 iu's of Vitamin D3 for a month, then drop to 10,000 iu's. I did this in January 2011. I didn't remember the 20,000 everyday, so it was hit and miss, closer to 4 times week. Then I had 10,000 maybe 5 or 6 times a week for 6 more weeks. A total of about 10 weeks.


In January I didn't know what my levels were at, but probably not high because I didn't take much Vitamin D3 from August until then and was very sick with the fibro flare-up.

I got tested 2 weeks ago and my Vitamin D3 was at 151! I was shocked. I am worried that it is too high. The doctor said to continue supplementing at 5,000 iu's per day, but since I was so worried said I could stop it for a couple of weeks then restart at 5000 iu's. I stopped it.

I am worried I am toxic. I want to know how long will it take to get my range back down to a normal range (lab test said 30-100 was normal). I mean around 60 to 80?

Thank you.

Stop worrying
by: Kerri Knox, RN- The Immune Queen!

Hi Lin,

Stop worrying, there has NEVER been a case of toxicity at a level of 150 ng/ml. Please read my page on Vitamin D Overdose. Most experts in vitamin d believe that toxicity begins around 250 ng/ml.

A level of 150 is actually found naturally in lifeguards in tropical areas like Hawaii and others who get lots of sun. But with your high anxiety over this and your Fibromyalgia, I suspect that you have Signs of Magnesium Deficiency and could benefit from some extra magnesium.

Thank you Kerri for letting me know that 151 ng/ml is not Toxic! What a relief! I am so glad to hear that lifeguards have this level, and it comes naturally to them.

I just found your site and it is amazing! I am so glad! I can't wait to check it out.

I could be deficient in magnesium. I just took a magnesium tablet a little while ago.

Thank you for your help!

Should I continue to supplement at 5,000 iu's of D3 per day as my doctor recommended?

Optimal levels
by: Kerri Knox, RN- The Immune Queen!

Hi Lin,

5000 IU's is a maintenance dose and therefore, to be used to maintain current levels. Since you probably don't want to maintain your level at 150 ng/ml, you could wait to begin taking the 5000 IU's when your level comes back down to 'optimal'.

Thank you Kerri, that's what I thought. I wonder how long it will take me to get down to the optimum level? I ordered Vitamin D test from ZRT laboratories. I was tested on April 4th. I will test again in a few weeks to see how far it's gone down. My doctor won't agree to test for 3 months and I am curious!

Thank you!

ZRT Lab Levels
by: Lin

Hi Kerri:

Just wanted to let you know that I got my Vitamin D3 levels checked at ZRT laboratories. I told you above that my levels were 152 on April 4th. So I waited until a full month had passed since I took a dose of Vitamin D3 and tested again on May 10th. I got my levels back and they were 39 from ZRT laboratories.

I cannot understand how the levels can drop that much (113 points) in 1 month. They were the same test, but one was blood drop at zrt lab, and the other was blood draw. I am wondering if there was a mistake made somewhere? Can Vitamin D3 levels drop this fast in one month? Where are my levels really at? I am confused. Which one is correct? Thank you so much for your help!

It didn't drop
by: Kerri Knox, RN- The Immune Queen!

Hi Lin,

Labs make mistakes and I suspect that the first blood draw was an error. It doesn't sound like you took enough to get your level up to 150 ng/ml and it was surprising to me that you were able to do that so quickly.

I would ignore your level of 150 ng/ml as if it didn't exist and assume that it's wrong. You can go back on a dose that will slightly raise your levels again, probably around 6000 to 8000 IU's per day for a month or two and get it rechecked. It should be into the optimal levels by then....

Thank you for letting me know that you believe the lab made a mistake. I have been wondering that myself. How could I drop so fast in several weeks? I will again start taking some Vitamin D. This mistake cost me a lot of Vitamin D! But I was fearful to take any more until my levels went down!

Thank you for your help! I will keep you posted.

Lin,
Can you please give an update on your condition?
I read somewhere that blood spot vs vein blood can yield different results and it's best to use same blood source for testing. Did you have your level retested with a blood draw?
