Your Vitamin D Blood Level
by: Kerri Knox- The Immune Queen

Hi Kay,

I'm not sure what 'Units' your Vitamin D blood test results are reported in.

This is very important to know because they are entirely different depending upon what the units used are.




More About Vitamin D


This is similar to being dropped by car into a foreign country and you did not know whether the speed limit was in Kilometers per hour or miles per hour.

If the sign said '45' without any units, you would likely be very confused.


So, here are the LOW END OPTIMAL Vitamin D Blood Level numbers from a research article entitled 'Calcium and Vitamin D Diagnostics and Therapeutics?:

45-50 ng/ml

or

115-128 nmol/L



So, if your Vitamin D blood level is noted in ng/ml or 'nanograms per ml' then HURRAY! Your Vitamin D level is exactly at the lowest end of normal optimum levels.

Whatever you are doing, keep doing it. But remember that you are at the very lowest end of normal and any decrease in your Vitamin D intake may make you go under the optimal level.





I suspect, however, that your Vitamin D blood level is likely reported in nmol/L or 'nanomoles per liter'.

If this is true, then you are quite deficient and need fairly aggressive supplementation to get your Vitamin D blood level up to optimum.

Let me know if you need any further help with interpreting your results or if you need any help with appropriate supplementation.

Vit D blood test results.
by: Kay Smith

My Vitamin D blood level results say:


20 - 100 ng/ml

Vit D Tot 50

Vit D D3 50

Vit D D2 <4

OP PENDING RECEIVED

Does this make it clearer for you?

Thank you for your response.
Yeah! Your Vitamin D Blood Level is Normal!
by: Kerri Knox- The Immune Queen

Hi Kay,

Yes, that does make it much clearer.
The numbers at the top that say 20- 100 ng/ml are the 'laboratory reference' numbers. In other words, the 'normal' reference range.

But I've talked before about how the normal reference ranges are calculated.


They take a whole bunch of 'normal healthy' people and take their blood. They exclude a percentage of the ones that are too high and too low. Voila, a reference range.

But we are now discovering that 1/2 to 3/4 of 'normal healthy' people are actually Vitamin D deficient.



What happens is that these reference numbers are not actually normal ranges for normal people- but rather the average range of a whole bunch of deficient people!



So many researchers have decided to calculate their own ranges by taking the blood levels of healthy sun exposed people- like lifeguards- and make 'optimal' reference ranges from that.


Looking at the next numbers, Vitamin D total and Vitamin D3, it appears that your number is:

50 ng/ml


According to our 'optimal' reference ranges, you are JUST at the bottom of the normal range.

You are NOT Vitamin D deficient, so whatever you are doing- Keep it up!!

But since you are at the low end of the range, if you get any less Vitamin D than you are now, then you could fall into the 'deficient' range pretty easily.



Also, if you are actively treating some sort of chronic illness or cancer, many researchers are suggesting that you get your level up a bit higher- like between 80 to 100.

In either case, since it's starting to get into spring now, you could probably just expose yourself to a little sun on a regular basis to keep your levels within the optimal range.



We are not really concerned with the D2 number. If your Total number is low, then the D2 number becomes important, but otherwise just ignore it.


Kay, you might want to consider getting your Vitamin D level checked again in 6 months to a year to make sure that it is staying within the optimal range.



But otherwise, you are doing great Kay!



I hope that I answered your question. Let me know if I can answer any other questions for you.

I REALLY NEED HELP.
low D
by: katydid

Can you help me with comprehending this

Vitamin D3 is 25 ng/mL
Vitamin D2 is <4 ng/mL

thanks
Interpreting your results...
by: Kerri Knox, RN- The Immune Queen!

Hi Katydid,

OK, so the Vitamin D 2 level doesn't mean anything, don't worry about it. It only matters if you are taking Vitamin D2.

The one that we are looking at is the 25, which is your Vitamin D Level. If you look at the Normal Vitamin D Level page, you will see that the researcher recommended 'optimal' vitamin D level is approximately between 40 to 80 ng/ml, depending upon whom you talk to.

So, you are definitely deficient- or insufficient in Vitamin D and need to get replacement. But DON'T let your doctor talk you into 'Prescription' vitamin d, you need to be taking Vitamin D3 Supplements. You can see why on the Vitamin D2 vs Vitamin D3 page.


I hope that this helped.

Vit D test results at 103 ng/ml
by: nathji

I am writing this from the Himalayan mountains in Northern India. I am an author who rarely stepped out in the sunshine. I had never had any Vit D tests done all my life. I had been taking four glasses of milk daily and still developed osteopenia. Where was all the calcium going? I realised soon enough that my Vit D intake was practically nothing.

So three months ago I began taking Vitamin D3 as powdered sachets of 60,000 IU available here in India. I took one sachet of 60,000 IU per week, and took this mega dose for 3 months.

At the end of the three months I got my blood tested for the first time through Grassroots.com test kit.

And the results showed

Vit D3 = 103 ng/ml

D total = 103 ng/ml

Their range is 30 -100 ng/ml

I am feeling fine. But all the same the high 103 ng/ml results worried me and I have reduced my Vitamin D intake to half -- half a sachet per week, i.e. 30,000 IU per week.

Did I do the right thing?

Does a high level of Vit D cause the bad cholesterol LDL to go up?

Thanking you in anticipation.

Yours,
nathji
What about the D2 numbers?
by: Maria

Vitamin D, 25-OH Range is 30 - 100 ng/ml

My testing results:
D3/ 47 ng/ml
D2/ less than 4 ng/ml
Total: 47 ng/ml

What does the less the 4 for D2 imply?
Should I be taking a D2 supplement?
Thank you in advance for your reply.
