I take 6000-8000 IU.
I take 5000 I.U., but only during autumn and winter or when I'm not getting any sunlight.
I've taken up to 20'000 IU Vitamin D after I read "THE MIRACULOUS RESULTS OF EXTREMELY HIGH DOSES OF THE SUNSHINE HORMONE VITAMIN D3 MY EXPERIMENT WITH HUGE DOSES OF D3 FROM 25,000 to 50,000 to 100,000 IU A Day OVER A 1 YEAR PERIOD" http://www.amazon.com/MIRACULOUS-EXTREMELY-SUNSHINE-EXPERIMENT-ebook/dp/B005FCKN2S/ref=sr_1_3?s=books&ie=UTF8&qid=1369136985&sr=1-3&keywords=vitamin+d

That's a miraculous book title.
In addition, I take good care to take it first thing in the morning. That's what I learnt reading Seth's blog: http://blog.sethroberts.net/
Yes, I also always take it in the morning!
I take a 5,000iu D3 pill twice a week. It's pretty sunny where I live, but I spend all day in the office. I take it first thing when I wake up.
@John Eels, When I got my first prescription D3 for 800 IU (lol) the G.P. instructed to take it in the evening, before bed.

Take the Vitamin you get from the sun before going to sleep. Seems legit.

I take it with breakfast.
I supplement with 500-1,000 IU in winter usually.
Lol, who actually thought pushing Vitamin D levels to supahigh amounts would bring about immortality?

Anyways, I'm going to get mine tested tommorow. Hope I'm not too deficient.
The supp contains vegetable glycerin so not lately.
@WrxSTI
In the evening before bed. Haha. Has it affected your sleep?
No because I never listened to them. I always took it in the morning and still do :P

Bottom line when it comes to vitamin D: U-shaped mortality curve.

35-40 ng/mL is the sweet spot and many supplementers grossly overshoot.

I do near-daily sun exposure in the warmer months and ~1200iu from food and milk. No supplements.

What do you think of this? :
http://www.ncbi.nlm.nih.gov/pmc/articles/PMC3092568/

Vitamin A is more common in food though, maybe that means it's more important and/or safer than vitamin D.

Peat said that Vitamin D has estrogenic effects after a certain point, probably with too high a dose. but it was someone else who e-mailed him so I don't have the exact words or citations.
That was some wishful thinking from 2009, that the existing studies on vitamin D and mortality represented unusual populations and could not be extrapolated from.

Since then, additional studies confirm that there is a U-shaped relationship between Vitamin D and mortality.  It should really surprise no one -- there is an optimal value for every nutrient, and every nutrient becomes toxic in excess.

Here's a recent example:
http://www.ncbi.nlm.nih.gov/pubmed/23533239

Its important to note that the vast majority of positive studies, reporting a simple inverse association of Vitamin D levels and mortality, have 25OHD levels over 26-29 ng/mL representing the highest quartile or quintile.  In other words, most people are deficient, and they are comparing a state of deficiency to sufficiency.
Ok, thanks!
I don't supplement...I assume I get enough D from the texas sun and sufficient amounts of half and half and cheese
I was outside shirtless for 30 mins every day last summer...my Vitamin D level moved up only a slight bit.

I assume the capability to make Vitamin D from the Sun in the hypothyroid person is, just like everything else, shot to hell.
Great answer, without blood tests supplementation needs to be conservative to avoid overdoses. I live in a sunny climate and just do 1200iu/day for the darkest months, and none april-september.
