Vitamin D

10 posts in this topic

Just a quicky!

My doctor has recently prescribed me vitamin d. The dose he's given me is 20,000 i.u.

This 10,000% the daily amount. Isn't this too high?!!

I've been taking them for over a week (hesitantly I must add), though I've stopped as the skin on my face has gone flaky and sore, and I've had gi ache (no idea if its related)

What's the normal dosage for vit d?

My bloods were at 44 (normal range 75- something!)

I am on 3000 IU and was measured as borderline. My bottle says 1000 IU per day. I was given more since my absorption is poor.

Well, Wiki says, "Vitamin D3 (cholecalciferol) is produced photochemically in the skin from 7-dehydrocholesterol. 7-Dehydrocholesterol is produced in relatively large quantities, 10,000 to 20,000 IU of vitamin D are produced in 30 minutes of whole-body exposure,[94] in the skin of most vertebrate animals, including humans..."

http://en.wikipedia.org/wiki/Vitamin_D#Production_in_the_skin

But I like for For Dummy's explanation of how the different types of skin colour affect vitamin D synthesis. For the most white types of skin, it only takes four minutes in the sun in the summer to synthesize 1000 IU of vitamin D. At the other end, dark skin requires 19 minutes to synthesize 1000 IU.

http://www.dummies.com/how-to/content/how-much-sun-do-you-need-to-make-vitamin-d.html

So, going by that, if you spent a couple hours in the sun and I'm sure you have, it would be the same as taking 20,000IU.

I think the danger would be if you were spending great amounts of time in the sun while taking 20,000 IU.

Thanks Kamma, very interesting! Perhaps my ailments are not related to the vit d then! It's just I saw that on the threads here most were on 2,000 or 3,000... And when I saw mine at 20,000! I wish I could grab my vit d naturally, I'd much prefer to sit in the sun. Fat chance in the UK though!

Thanks again for all your help :)

Thanks Diana, that's what I thought most here were on... And that's why I thought mine was particularly high!

Hi DS-

I was on the extra powerful Ds just before I was diagnosed -- I remember them being 50,000 for just one week -- may be mistaken -- perhaps they were only 20K. How long does your doc have you on them? Since you've removed gluten, I would think that soon you'll be able to drop down to a regular D supplement -- perhaps have your D checked by blood after some time on the supplement to see if it has brought your vitamin D back up?

I was taking 50,000 once a week to begin with, with some daily 1,000's in between. My doctor said my tank was so empty that taking a regular dose would barely give me enough gas to get to the next gas station. So you have to fill the tank first, and you will not be absorbing all of that 50,000, but keep getting your level checked and when you are mid-range you can cut back. I am sure she did not intend for you to keep taking this dose forever. I now take 50,000 once a month.

Hello friends! Sorry for delayed response I've been cleaning kitchen cupboards for my new (almost) gluten-free kitchen!

My doc has me on these vit d supplements for z month. Must admit I have stopped taking them. I may just take one every other day and take a normal lower dose one on the missing day?

That's a really high dose and not so smart of you doctor not to give you any directives. From what I heard 5000 IU a day should be enough for an adult and probably not necessary with more than 10000IU/day
