7,7 ng/ml Vitamin D level: How long to supplement with 20.000 IU

Answered on August 19, 2014
Created August 25, 2011 at 1:15 PM

My Vitamin D levels were tested 7,7 ng/ml, so I went to a physician and said I needed a prescription for Vitamin D. He said my levels were not really high and prescribed me 20.000 IU.

How long it is best to take it before doing another blood test to check the levels? I was advised to take one pill per week. I am dark skinned and don't get much vitamin D from the sun.

Just a quick note: In Germany it really is IE (Internationale Einheit(en)), but it means exactly the same as IU (International Unit(s)).

As I wrote, I am dark skinned. Not really high latitude, more southern.

Primordial, do you live at a high latitude and/or have dark skin?

lol. Yeah, it's low. Akman, thanks for your answer, very insightful. My inflammation marker (CRP) is low (0,1) but you might be right. Especially because I enjoyed months of sun exposure before having this low level.

I would retest in 3-4 months. And see if you can't get some actual sun. There is evidence that sunshine has extra benefit.

I've got D3 prescribed. Here in Germany most seem to know that D3 is better. Over 5.000 IU or so you need a prescription.

Why did you need a prescription for Vitamin D? I ask because it's my understanding that doctors generally prescribe D2, when D3 is less expensive and OTC, and many D advocates prefer D3.

I don't know what you should do. At 7.7 I would take 10,000 IU a day with fat and test in two months.

7.7 ng/ml is a super-low level. Personally, I aim for 50-80 ng/ml.

I would definitely take 10,000 IUs daily for at least 3 months & then retest.

If IEs=IUs, then 20,000 a week is not going to be enough.

My wife's vit D level was 7 also. She was prescribed 50,000IU pills of D2 to take twice a week. They told her to come back in 12 weeks. She's also taking 5000IU of D3 several times a week that the doctor doesn't know about. Her platlettes also were slightly elevated.

I heard from a reliable source that vit D levels this low could point to something very sinister...it may mean there is inflammation or a serious underlying condition that is 'using up' all the vit D in the body. Wife has appt with oncologist today, hopefully they will order up some really good labs to get to the bottom of this.

Also, if your vit D is way low, good chance you have bone issues as your body can't absorb calcium w/o vit D. Make sure you take the vit D with a fat such as coconut oil or after a meal w/plenty of fat.

Carlson's D Drops. 4000 IU per drop. Uses coconut oil as the base. Best one on the market in my opinion. FAR superior to paying 55 dollars per month on Green Pastures FCLO. Seriously, why not just spend 55 dollars on fish instead? FCLO is an abomination. We evolved with fresh fish, not fermented fish oils. Think about it.

So the wife goes to the oncologist today who is also a hemotologist and he checks her platlettes. Finds the are still high, just maybe 10% above the range. Says it's worrisome and wants to recheck her in 90 days. Says if it's still high he wants to do a bone marrow biopsy. Also says her super-low vit D level is completely unrelated. He didn't order any labs. I think he's a quack and we need a new dr.

When you're dark skinned and live in Germany, then your Vitamin D3 level is not a surprise. If you are dark skinned because you/your family originally came from another country, then you definitely need to supplement at a little higher doses, probably for the rest of your life.

20.000 IU per weeks is not very much. But I don't agree that you necessarily need to take 10.000 IU/day or more, although I am not saying that it's bad, either. Let the blood level guide you.

Here's what I would to:

Take your 20.000 IUs per week as prescribed for 3-6 months and then get tested again. You now know which blood level you can expect from 20.000 IUs per week.

You then need to decide if you are ok with your blood level or want to go higher/lower. If you want to go higher, double the dose and get retested after 3-6 months.

Through this approach you can dial in your dose. I don't think a level up to 80 ng/ml is necessary. Most of the arguments I have found for levels that high are very very thin associations with very limited data. It doesn't mean that a level of 80 is bad, it just means I am not convinced it is beneficial. But you should definitely get your level above 20 ng/ml and I think 30-50 ng/ml is a good range to shoot for.

As I already said, it is not clear at this point if higher levels really do have benefits and don't have adverse effects, so if I had a level of 7.7, I would be more concerned with getting it over 20 or 30 than to shoot for some arbitrarily high number. The jump from 7 to 20 will probably be more beneficial than the jump from 20 to 50, anyway.
