But in reality the amount of D3 you are taking is very minute.
1000IU of D3= 25 MICROGRAMS.
So in reality D3 is a very small amount taken daily. 4000IU would be 100 MICROgrams.
As a comparison, some MS treatments today keep the patients at testing levels of 100! This is THEIR goal... because the thinking for MS is that low D factors into that disease some way.
For us, a goal of 50 (or at least 40 which I keep) is acceptable.
I can really feel my D levels drop around late Sept and Oct from all the sun I get in summer. So I take about 10,000 IU every other day in winter. (sometimes less). I use Puritan's brand...very inexpensive.
The 1000IU rule is an approximation. Some people may need more, and some a little less. At 5000 IU daily I tested at 43...so I am one of those who need a little more.

my D levels agree with mrsD rule of 1000IU for every 10 points needed
after I was dxd with cidp (peripheral nerve version of MS) my integrative med md advised me to take 10,000IU vit D3 daily
my initial vit D level was below 30 b4 I supplemented
after 120 days, which = time for your entire RBC to "replicate", my level was 117 (anything >100 = potentially toxic)
dropped to 5000IU WEEKDAYS only, then level was 54.3
advised to add an additional 3000IU daily, so I take 5000IU one day, and 10000IU the next
will test again in another 120 days to see where I am
bottom line
1. get initial test b4 you supplement
2. use mrsD rule of 1000IU for every 10 points needed
3. get retested in 120 days and see where you are at
ideally, my integrative MD wants me to get to 90...within 10% of upper range for my condition
but your mileage may vary...follow your physicians instructions
