10,000 IU per day. A loading dose is in the range of 100,000IU to 1,000,000IU, depending on age and body weight. Hypervitaminosis D only occurs when you take a loading dose level for months or years; it's not possible to acutely overdose on vitamin D.

That's a lot. Vitamin D tests are easy to get, so I just took a few over a few months to find a dose that would keep me at ~50ng/ml. Previous to that, I had taken 5000+ IU/day for some time and the test showed my levels were very high.

It looks like this site has a nice chart: https://www.vitamindcouncil.org/further-topics/i-tested-my-v...

I did end up taking a Vitamin D test after I had started supplementing, and on that dosage I'm still a little below normal levels.
