Vitamin D testing

Dian,

Where you get tested is very important. Also is it for vitamin D2 or vitamin D3? If your number is actually 25 for vitamin D3, you are WAY below normal. A person fighting cancer show be in the D3 high range between 90 to 100.

Best wishes,

Gene

I have chronically low vitamin D levels.  When they were first discovered, I was at 7.  I have been under treatment by a couple of different docs, and highest my D ever got was 25.  The last time I was taking 50,000 units 2X per week I only got it up to 19.  As soon as I am off of it, it plummets again.  No one seems to know why this is so hard for me. 

I have not heard the 90-100 levels.  My doc was trying for 50.  Any ideas on what else I can do?

I found this list of ranges on the internet. Internet information isn't always correct but it came from an article that otherwise seemed accurate.  The confusion here could be that  ranges can be given in ng/lm and mnol/L.

Also, if you do a search you will find foods that also provide vitamin D.

Serum level ranges

For optimum health, vitamin D blood levels should be around 50-80 ng/mL (125-200 nmol/L).

ZRT lists a lab reference range for vitamin D at 32-100 ng/mL. Reference ranges represent the range of values that the majority of the population will fall between and are not indicative of values which would be considered optimal.

Studies indicate that for proper health, serum vitamin D levels should be a minimum of 50 ng/mL (125 nmol/L), with optimal levels falling between 50-80 ng/mL (125-200 nmol/L). These values apply to both children and adults.

sorry for the confusion Gene. What I meant was that the D 25 is the test I take.

My Vitamin D levels are normal now. They used to be way below normal.

I began testing vitamin D levels not because of my melanoma, but because I had a problem called hyperparathyroidism.. It was a benign tumor on one of my four parathyroids. Not all that rare a condition, it causes a rize in calcium levels in the blood and is one of the causes of osteoporosis. In my case it also caused very low vitamin D levels (mine were down to 13 at one point) SO I did (and still do) vitamin D  supplements.

I had surgery to remove my bad parathyroid a couple of years ago, and I continue to supplement, but my vitamin D levels are quite normal now.

thanks for your concern, and sorry for the confusion

Hello William,

It is very nice to see that people are finally starting to have their vitamin D levels checked.  The suggested Vitamin D range for people fighting cancer is between 90 and 100.  The proper amount to take is 30 – 35 times your weight.  ie a 200 pound person should take between 6,000 and 7,000 of Vitamin D3 daily.  It should be spaced out during the day and not taken all at once.  As far as high range problems you would have to be seriously in a very high range for any problems.  The best Vitamin D is from the sun many people on this board will throw rocks at me for that statement but 10 to 15 minutes a day at lunch time will not only make you feel a lot better but will also help you raise your natural Vitamin D significantly.  Do a search on my profile for past articles on Vitamin D and blood testing for there are links to many good websites. 

As far as asking your doctor, you probably know more about Vitamin D than he does.  Doctors are more intuned to know about Vitamin D2 and very little if anything about Vitamin D3.  Doctors are taught very little about nutritional value or supplements.

Best Wishes,

Gene
