Maria Fisher46 said:Vitamin D levels are clearly measured in nmol/l—in this case, 166 nmol/l. That level isn't considered toxic just yet. Usually, we don't start talking about toxicity until you cross the 375 nmol/l (150 ng/ml) mark.
That said, whether 166 nmol/l (66 ng/ml) is an ideal number... well, that’s definitely up for debate. Some might call it "high-normal," others just "normal," and then there's the question of whether there's actually any extra benefit from that level compared to, say, 125 nmol/l.
The tricky part is that studies haven't quite nailed down what the "perfect" vitamin D blood level should be specifically for people living with lupus.
Since you were deficient before starting supplements, I'm not entirely sure if you should stop taking it altogether or if it would be smarter to just scale back—maybe try 1000 IU a day and then retest in three months to see where things stand...
Nicholas, I've been waiting for you 😁—I remember you gave me some general advice on Vitamin D a few months back.
Since I have those 10,000 IU capsules, would it be okay to just take one every ten days?
I know that here in the US, some patients get prescribed 50,000 IU once a week (though I guess it depends on the doctor), even though from another perspective
it doesn't seem quite right. Taking an extreme dose one day and then nothing at all for the rest of the week... I kind of struggle with that logic.
P.s. Is nmol/l the standard unit?
