so I had the results back from multiple blood tests and it says I am quite vit D deficient. fair enough doc prescribes supplements.

but Im a bit concerned with the righting on the pescription. it said take 2 a day, ok thats fair enough, but it also says 2,500 unit.

is the 2,500 unit the strength or the amount of pills I am getting?

and if it is the strength is that really high or normal?

2,500 is the strength, known as IU. You'll need to take a high strength to get your level up. Give it a few weeks, you'll start to notice the difference

ah yeh I did think I would need a high dose to get it back to normal.

but as you get vit D from being in the sun.

an I hardly every go out in the sun, cause of the meds im on I am more at risk as getting skin cancer, would that make my lvls quite low??

and is 2,500 a high amount? a really stupidly high? or not that high?

If you're trying to get your levels up you may need to be taking more like 20,000iu a day for a short while. 2500 is more like a daily dose to maintain what you have. I've read posts from people who have been on 10,000 a day for a month and their levels have hardly moved.

RDA for the UK is 200 IU, but other govts reckon more - Canada suggests 800 IU for instance. So 2500 IU is a high dose but nothing that crazy.

Getting an adequate daily intake of vitamin D from diet requires a high intake of oily fish (at least 100g per day). The lack of dietary sources of vitamin D is probably why humans (and other mammals) evolved to be able to produce it in their skin. At our latitude the sun isn't strong enough in autumn and winter to provide sufficient vitamin D, so you basically have to supplement it (or eat a lot of fish).

Apparently if you live any further up't north than Birmingham, it is likely you will be vitamin D deficient anyway, due to lack of sun. Supplements should really be taken by alot of people (particularly those who cover up).

I work for a Canadian company and we all got a full suite of blood tests a couple of years ago. They also presented graphical evidence on Vit D and how northern Europeans are generally deficient in it. We get given D drops for free and i started out on 10,000IU a day for a month, have been on 5-6,000IU a day for the last 2-years.

I did notice a subtle improvement in my mood/outlook, but not exactly scientific and i've not had another blood test since.

Having said that...Before Christmas i developed Salmonella and stopped taking the drops. For some reason i seem to have gotten out the habit of taking them again. I've now noticed a difference in my mood and i seem to get more hunger pangs, so need to get back into a routine.

Btw, that was a rhetorical question.

But the sentiment was based on the flawed basis that eating a proper diet will give you sufficient vitamin D, which for the majority of people it won't.

Yes it will. You said it yourself, eat 100g of oily fish per day. Nothing is flawed about eating how you're designed to eat. A proper diet for Humans is our primary protein source oily fish... I can reason and argue... they are also our primary vitamin D, B-12, phosphorus, magnesium, potassium, polyunstaurate and Omega 3, 6, 9 sources. Or in other words, as a single food source, almost exactly everything we need. Ho-hum.

So why don't we live in the sea where the food is? wink

well perhaps, just perhaps there are reasons, like they are quite ill.

I have to have iron, calsium, vit D, supplements, plus a few other drugs that I cannot get what they contain from any other source other than the pills / infusion.

so, yeah.....please refrain from that sort of thing until you actually know why people take them.

and i dont really thing it was a rhetorical question tbh, because that would not require a answer, but yours did.

Who said anything about the sea? We followed the coast-line and river deltas all the way from East Africa to the Middle East and on to Mesopotamia and the Tigris... water, water everywhere for an animal that needed to drink more than any other. (I have book's-worth in reserve here)

In East Africa and the Middle East we get more than enough vitamin D from sunlight so it's irrelevant how much fish we ate.

Good point, but it's not just vitamin D. As I said, oily fish (so far as scientifically known at least) provide a near perfect balance, requirement and source of B-12, phosphorus, magnesium, potassium, polyunsaturate and Omega 3, 6, 9 sources, not forgetting high quality protein, even in a form we can eat raw, and even fats in a superb sat:monotongue outoly ratio.

Vitamin D is actually just an aside that crops up here. Otherwise, yeah we should all be dark-skinned living near the equator... unless you're an Inuit.. who get loads of vitamin D through their fish diet anyway...

Do most of these supplements come in pill form as prescriptions?
