Hi MZ,
I think you should first ask your doctor to help you normalize your vitamin D level, and then ask him to help you find the regimen for keeping it normal. Better Vit D level is not a cure in itself, but sure helped a lot of POIS sufferers to lower the intensity and duration of their symptoms.
In my case, I have aimed more to 40-45 ng/ml than 30, 30 being the low side of the target. It made and still makes a difference for me.
How many vitamin D ius are normal in a week, the doctor gave me 200000 ius in a week, after a month I was normal on vitamin D levels then he stopped treatment and after that (about 2 months) I am again low on vitamin D, kindly advise me to adjust the dosages to keeping it in the normal range, the doctors here don't understand the condition fully
If you are living in a place where there is plenty of sunshine, and you are often outdoors with exposed skin to the sun, you need less. If, like me, you live up north where summer is short and winter is long, you need more. It is better to take a smaller dose of vit D every day than taking a huge dose once a month or once every 3 months.
2000ui a day is a safe dose and a majority of people will hit the target with this dose. Personally, I take 2500ui a day, the Jamieosn brand (
https://www.jamiesonvitamins.com/products/vitamin-d3-2-500-iu ), After one year, I got my vitamin D tested, and it was at a good levelThe way to check your vit D level is to test for 25-OH-D level in the blood. There are two main scales to express the results,nmol/L and ng/ml, so you have to be careful in what unit your blood test result is expressed.
Many doctors will be happy if you get over 75 nmol/L ( 30 ng/ml), but many studies have now shown that 100 to 150 nmol/L (40 to 60 ng/ml) is a better target to get all the benefits for the immune system. There is no toxicity at all at those levels, and people living in very sunny environments can naturally get a level of over 150 nmol/L ( 60 ng/ml), so 100 nmol/L (40 ng/ml) is really not a concern.
When someone has kept the same daily dosage for a few months and gets blood test results, his doctor usually will adjust the dose depending on the result. If the result is too low, studies have shown that every 1000ui more a day will raise the 25(OH)D level by around 25 nmol/L ( 10 ng/ml). Since not everybody absorbs vitamin D the same way, further blood tests will be necessary to evaluate the new dosage's results.
My last blood test showed that my 25-OH-D was at 108 nmol/L ( 43.2 ng/ml), and I was glad about it, so I kept my 2500ui per day dosage.
