Not the right level..

Glad that you subscribed and will get this. OK. So, first of all, Prescription Vitamin D is less potent than Vitamin D3, so you may not be getting all of the benefits that vitamin d would have offered you when you took the prescription vitamin d.

Next, so your vitamin d level is now 34. While your lab test and your doctor will tell you that that is 'normal', according to researchers, it's not 'optimal'. Please read my page on Vitamin D Levels to see why your level is not nearly high enough.

Therefore, you are going to need a much higher Vitamin D Dosage than 1000 IU's. 1000 IU's is a maintenance dosage for a newborn infant and not for an adult.

Next, while most people who have fatigue and other issues are ECTASTIC when they find out that they have vitamin d deficiency and want that to be The Answer to their problem- but if you are not feeling better at higher dosages you need to consider that vitamin d deficiency is NOT your only problem.

So, fatigue and pain could be:

Vitamin B12 Deficiency Symptoms

Symptoms of Gluten Sensitivity

Signs of Magnesium Deficiency

H Pylori Bacteria

and on and on.

So, while I don't want to be negative, it's rare that people with severe health problems have only ONE thing wrong with them- and usually people need to address some diet and lifestyle issues before they feel better.

Vit D question
by: lin

I have the opposite problem My Vit D tested in Jan was 9 no D2 or D3 levels were given. Just tested again after taking prescription Vit D (50K weekly 10 weeks). Test results are Vit D3 is 8 and Vit D 2 is 36 making a normal range of 44. Calcium is at 9.5 boarder line high.

This is not a 'problem'

Hi Lin,

This is not a 'problem'. You are taking vitamin d2 (prescription vitamin d), therefore your vitamin d2 (and total vitamin d) level will go up and NOT your vitamin d3 level. If you were to take vitamin d3, your vitamin d3 (and your total vitamin d) level will go up.

You CAN'T raise a vitamin d2 level with vitamin d3 and you can't raise a vitamin d3 level with vitamin d2 - and you DON'T NEED TO. ALL that you are interested in is the TOTAL NUMBER. If you are taking ANY vitamin D, it will raise your total number.

In your case, your TOTAL was raised from a level of 9 to a level of 44. This is a NORMAL PHYSIOLOGIC RESPONSE to taking Vitamin D- your vitamin d levels go up and your level is now PERFECT. IGNORE the vitamin d2 or vitamin d3 levels, they are only telling you the KIND of vitamin d that you are taking. You now need to go on a maintenance dose of vitamin D3. Then your next level your vitamin d2 level WILL go down. IGNORE IT. Only pay attention to your TOTAL NUMBER.

Please look to the right of this page towards the top and subscribe to my newsletter, you get my Fact Sheet on Vitamin D for free and that will answer your questions.

PS. When you ask someone about your vitamin d levels, you should include the UNITS. 58 means nothing to me without a UNIT of measurement. Just like if you were driving 58, you would need to say km/hr or miles/hour to communicate what that means to someone else. Depending upon which units you are using, your vitamin d level is either perfect- or you are SEVERELY deficient. Read my Fact Sheet to find out.

Also, there is no such thing as vitamin d1. Maybe you mean 1,25 OH D?? Which is NOT a 'Vitamin D' level.
