Vitamin D
« on: January 19, 2010, 05:13:08 AM »
I am not getting much from my diet and not able to go out during daylight at the moment. No sun anyway in London!

I was going to supplement with 1000iu per day - then I saw this!

12.5mcg Vitamin D3 = 500iu.
Each extra 100iu/daily raises 25(OH)D ~ 2.5nmol/l
Average UK adult status January = 30nmol/l
Natural primitive level at which human breast milk is replete with D3, babies are born with optimum bone mineral density = 147nmol/l
Least incidence of chronic illness is found is between 125 ~175nmol/l.
Least Diabetes Type 1 found at above 132.5nmol/l.
Most UK adults therefore require 5000iu~6000iu/daily EXTRA vitamin D3 in order to achieve the natural primitive vitamin d level our DNA evolved to work best with.
The Risk of Additional Vitamin D Reinhold Vieth shows 10,000iu/daily is absolutely safe.

Help. 5000 daily? wow. is this necessary in your collective opinions. Also I think the cost is going to be prohibitive!

I take 6000 IU per day.  I test every six months and am almost to the point of not being deficient.  I live in the northern US, and have a condition where I get hives if I spend more than 10 minutes in the sun from March until October...so I need it.  Having said that, most people in northern latitudes are deficient.

Price's research demonstrates that traditional groups including some that lived completely paleo, apart from being exposed to the sun, got plenty of vitamin D from their foods. They ate at least four times the recommended amount, so take 2,000 IU of vit D. The same is true for vit A, and you should consume 10,000 IU of vit A. The best way to do this is a high vitamin cod liver oil or butter.

Half an hour, completely naked, in the sun, at the equator (best case scenario) produces 10000IU of vitamin D.

I take one 5000IU pill in the morning, and one 1000IU pill later in the day. Some people recommend as much as 8000IU.

Well i had someone pick me some up at lunch time 7.19 for 90 1000iu capsules.
I certainly cant afford to pay 10times that. I do eat salmon quite a lot and I like sardines.

I took 2000iu today.

Have any of you noticed feeling any different taking the D3? What should I look out for? Or just take it on trust that it is doing me good?

Thanks for all the replies by the way.

I take 5,000 a day when I remember to do it.  I have chronic fatigue syndrome and I have noticed that when I take the D on a consistent basis I feel a bit better.  Nothing has made me feel as good as taking the junk out of my diet, but I do think the D helps.

I take mine in liquid drops.  I got them at a local vitamin store for about 10 dollars.

It helps me feel more energetic in the morning, but the biggest thing I noticed is that it does affect the immune system.

In the past, we suspected Vitamin D was mainly for bone health, but more recent studies have shown some amazing effects. 5000IU/day is enough to treat depression in some people, and it's show to have a large impact on the immune system as well.

Is anyone aware of a study of the effects of comparative doses - I can't see anything googling it
This is all very interesting.

Yes, it's the best source of vitamin D. I posted this previously in the vitamin D thread under "Vitamins", but I'll post it here too. It's a vitamin D by sun calculator:

What is the cost Eric?
May I ask?


You can get over a hundred 5,000 IU pills of D-3 at iHerb for less than $10.  Use the code ZEB079 when you check out to save $5 and support the site.

Their supplements are the best quality and price with high turnover, ensuring freshness.
