Supplement with D2 or D3?

by Nana

My rheumatologist prescribed 50,000 IU capsules to be taken 1 per week for 5 weeks, in response to my Vitamin D levels of 11 ng/ml. She prescribed ergocalciferol.

I went to see her because I had been having muscle cramps that woke me 2-3 X/night, and also occurred several times during the day. I have taken the last of the capsules, and the cramping has significantly decreased both in frequency and intensity.

However, everything I am reading says that Vitamin D deficiency should be treated with vitamin D3 rather than vitamin D 2.

I do not know if the Vitamin D assay that was done included both D2 and D3 levels. I am scheduled for a follow-up visit next month.

Should I ask her to recommend or prescribe a vitamin D3 supplement?

As of now she is my hero, because no one else has been able to help resolve my muscle cramps problem.

Muscle Cramps and Vitamin D
by: Kerri Knox, RN-The Immune Queen!

Hi Nana,

I'm glad to hear that your problem is finally getting resolved. However, it's practically criminal that doctors are STILL not checking Vitamin D Levels when Vitamin D Deficiency is a known risk factor for cancer and heart disease.

You are actually LUCKY that you were having these muscle cramps because it urged you to find out the source of the problem and get your Vitamin D Levels corrected.

In the process, now you have a lower risk of heart disease, many cancers and osteoporosis.... yeah!!!

So, PLEASE pass this along so that other people will Get their Vitamin D Levels Checked too and reduce THEIR risk of these diseases as well!!

As far as Vitamin D2 or D3, it is always better to have Vitamin D3 because it's half life is longer and it is absorbed better, but vitamin D2 does not HARM you in any way and it is what doctors have at their disposal for high dose vitamin D therapy, so it is certainly better than not being treated at all and it does work to bring up your levels.

However, treatment for 5 weeks will likely not correct your vitamin D deficiency and it would be better to get treated with the 50,000 IU's for several more weeks and then get retested.

After you get your level up to the OPTIMAL range of between 40-60 ng/ml (NOT the 30 ng/ml that is the low end on your lab test), then you should begin to supplement at a dose of between 3500 to 5000 IU's of over the counter Vitamin D3 per day in order to maintain your level.
