My Doctor has me on 50,000 IU of vitamin D a day and I was wondering if this is too much.
The Doctor said they will retest my vitamin D in one month, it was continuing to fall after taking 50,000 IU weekly. I am concerned about taking so much.
My physician has prescribed Vit D3 60000Iu 2 TIMES A WEEK FOR 4 WEEKS AND LATER ONCE A WEEK FOR 12 WE3KS. iS THIS LEVEL SAFE?

Vitamin D3NEW by: Anonymouse
Last year, I was found to be mildly vitamin D deficient. I took a basic supplement for a couple of months and then forgot about it. This year my D levels are seriously low. My doctor seemed worried. She has me on 50000 IU once a week. I wasn’t paying attention and thought I should take it once a day, luckily I caught it after 3 days. I’m glad to hear it’s not toxic. Reading up on Vitamin D deficiency, I realized that everything that’s wrong with me - muscle aches, low energy, maybe even my anxiety disorder and newly found prediabetes are caused by this deficiency. Who knew!
My doctor was very emphatic that I take D3.

Not toxic by: Kerri Knox, RN
You'd have had to have taken millions of IU's to become toxic. Just get a level and have your level tested. Simple to find out if you are toxic if you are concerned about it.
And we need Vitamin D all of our lives. Taking a giant amount for a few weeks just gets the levels up to optimal. To maintain levels, you'll need to take a maintenance dose or get regular sun.
It's not just important to get your level up once, but to keep it there. Please read this thread again, as I've outlined specifically how to go about doing that.

There is no toxicity problem... by: Kerri Knox, RN- The Immune Queen!
Hi Theresa,
If you are in the US, you either misunderstood your pharmacist or he did not tell you the truth. In the US, there IS NO prescription Vitamin D3. Period. End of story.
And there are NO toxicity problems with Vitamin D 50,000 IU per week no matter which form that you take. When I say that Vitamin D2 has a higher risk of toxicity, we're talking no toxicity until millions of IU's are taken no matter which form that you take. All that I mean is that it takes less Vitamin D2 to reach toxicity than Vitamin D3. But in any case, 50,000 Iu's per week will NOT cause toxicity in an adult. Period.
But please consider getting D3 and ditching your prescription.

50,000 IU of Vit D versus Vit D3 by: Teresa
I understood the pharmacist yesterday that the prescription 50,000 IU is Vitamin D3. Given that D3 is more effective than D, is 50,000 per week of D3 OK or a possible toxicity problem?
Please clarify, & thanks!
What an informative site!

Be more afraid of vitamin d deficiency by: Kerri Knox, RN- The Immune Queen!
Hi Elena,
You should actually be much more afraid of being vitamin d deficient that of taking too much. Please read my page on Vitamin D Toxicity page and you'll see that for over a decade in West Germany, it was 'Standard Practice' to give Newborn Infants 600,000 IU's of vitain d at birth and every 3 to 4 months after that until they were 18 months old.
This gave them over 3 MILLION IU's in less than 18 months without causing any health problems!!!
While I don't recommend taking that much, you may need as much as one million IU's or more to get your vitamin D level up to normal. If you take 50,000 IU's per day for 30 days, that's 1.5 million IU's. While doing this for a long period WOULD harm you, doing that once to get your level up is FINE and is a very good way to bring your level up. But you need to make sure of several things:
1) You absolutely should be sure to read my page on Prescription Vitamin D to see why taking your doctors prescription is NOT recommended.
2) You should not continue taking the 50,000 IU's per day for NO MORE THAN 1 month.
3) You need to get your level checked again in 2 to 3 months (not taking any more vitamin d until then is fine- vitamin d lasts several months because it's stored in your fat)
4) You need to make sure that your level is within the 'OPTIMAL' range as outlined on my Vitamin D Level page- do NOT use the levels on your lab sheet. They are NOT optimal.
5) Be sure to get on a MAINTENANCE dose after your level is within the optimal range. Please see my page on Vitamin D Requirements page for the RIGHT maintenance dosage.
6) PLEASE PLEASE be sure to take magnesium with your vitamin d as outlined on my Magnesium Dosage page. Vitamin D 'uses up' magnesium when you take it and I can almost guarantee that you are going to become magnesium deficient taking that high of a dose. But you can completely avoid that if you simply take some magnesium as well.
Please don't worry about the dosage. Be HAPPY that you have discovered this problem and now have a solution.

I'm so scared because it seems so high but that was prescribed to me once a day - 50,000 iu! Doc said I am deficient and wants to pump my Vitamin D levels immediately.

Vitamin D 50,000 IU's per day by: Kerri Knox, RN- The Immune Queen
Answer:
While Vitamin D 50,000 IU per day would DEFINITELY be too much for long periods of time without getting levels drawn, it can be an appropriate dose for short periods of time when you have known levels and you were not responding to the previous dose that you on.
You made an excellent point for the board, however. 50,000 IU's per week of Vitamin D often is not even an adequate maintenance dose for many people. In your case your level was DROPPING while taking over 7000 IU's per day- what most doctors consider an EXTREMELY high dose!
You are NOT unusual, most people actually need these high doses, but it is just not recognized because most people do not get their Vitamin D Level Checked or, even if they do, their doctor gives them 1000 - 2000 IU's of Vitamin D per day and never checks their level again.
So, this high dose has a precedent, so you are definitely not the first one. A study gave a group of healthy young men 50,000 IU's per day for 6 weeks and there were no signs of toxicity. So, as long as you get your level checked in a month, you should be absolutely fine.
