Is 50 000 IU's a Day of Vitamin D Going to Make Me Overdose?

by Nichole
(Coshocton, OH)

I have been diagnosed with an extreme vitamin D deficiency after having blood work done and my doctor prescribed me 50,000 IU of vitamin D a DAY! The pharmacist where I get my prescriptions filled says he's never heard of anyone taking this high of an amount daily.


I have also heard that doctors usually prescribe a calcium supplement while on high dosages of vitamin D, which he didn't prescribe. I'm very worried about Vitamin D toxicity with these high amounts..

Could someone please help me and let me know if this high amount should cause concern?

Thank you!

Not so concerned about the dose, but...

Hi Nicole,

I'm sure that your doctor gave you a specific number of pills, right? It's not an UNLIMITED prescription, but a set number of pills.

So, I'm betting that if you add up the TOTAL dosage that it doesn't exceed a couple million IU's or so. But even if it does, there have been plenty of studies on healthy young men getting a million and a half units over a 3 month period without any problems.

And for many decades, NEWBORN infants in East Germany received a shot of 600,000 IU's all at once every 3 to 4 months until they were 18 months old without any problems. So, really, unless you take that for longer than two months, it will be fine. Just make sure that you get a level after the end of 2 months or so at doses that high.

You do not NEED to take a calcium supplement with that. It's likely that you haven't been absorbing calcium for many years because your vitamin d levels have been so low, but Vitamin D will get you to be absorbing your calcium now!! Most westerners get PLENTY of calcium, we just don't absorb it because we don't have enough vitamin d or magnesium.

And that leads me to the next subject. Please consider taking a magnesium supplement with your Vitamin D because it USES magnesium when you convert Vitamin D supplements into their active form in the blood, so the very few Vitamin D Side Effects that occur are almost always due to a magnesium deficiency that is provoked by taking Vitamin D!!!

Also, the one real concern about your regimen is that your doctor gave you a prescription for vitamin d in the first place!! Read my blog post to find out why you should NOT be taking Prescription Vitamin D, but rather you should be taking Vitamin D3 supplements at the same dosage instead!

Thanks for writing in, I hope that this helped ease your mind. Please write back and let us know how many tablets he gave you to take.
