I had my Vitamin D level along with other blood tests done in April. My Vitamin D3 level came back at 6 and my D2 level was 4. My potassium levels which have been low for a long time was also very low 3.3 but not as low as it has been in the last (0.9 in Jan 2011 required hospitalization). My doctor put me on 50,000 iu once a week for 8 weeks. I noticed some changes fairly soon as my head began not to sweat as nearly as much as it had been. I also became regular as far as bowel movements. I have Crohn's disease and other intestinal issues that have caused me problems for years. I have now been off the Vitamin D for about a month and I am starting to feel off again as well as my bowel habits have again become erratic and my head has again begun to sweat. How long does it take for Vitamin D levels to normalize and stay normal when they are as low as mine were? Should I request to have a prescription for Vitamin D? My glucose, TSH, T3 & T4 levels were all within normal ranges.

    Sometimes people assume that once you increase your Vitamin D levels into a reasonable range that they will then be OK and there is nothing else to do. Vitamin D needs to be taken daily for the rest of your life unless you live near the equator and can get sun year round. Your body uses huge quantities of it to regulate the genes in the human body. So if you discontinued taking it, without going to a maintenance dosage, then your levels will fall really fast.
    So if the original prescription was for D2 and not D3 you should take note that only D3 should be used from now on. It is better for you. Luckily D3 is available over the counter. So you could take 50,000iu once a week for 8 weeks again and then try a maintenance dosage of 5000iu a day. Or you could just take 7000iu to 8000 iu per day and then after 8 weeks drop back to 5000iu per day. We like to promote daily usage if possible.
    The good news is there is a lot of research that points to Vitamin D helping or possibly even curing Crohn’s.
    It is very important to read http://www.vitamindcouncil.org/about-vitamin-d/vitamin-d-and-other-vitamins-and-minerals/.
    You are also trying to reach a blood level of 50ng/ml minimum. Anything below that is just not good enough to get and keep you healthy.
    So back on the Vitamin D you go and it would be great if you could get someone to check the level again once you have been taking it again for awhile. Just to make sure you reach and stay at the 50ng/ml or greater. (So maybe retest in 4 months.)
    Hope you feel better soon and come back and let me know how your Crohns is doing.
