Another thing to remember with Vitamin D is that it's a fat-soluble vitamin. There are four of those: A, D, E, and K. Those four can build up to unsafe levels in the body. Other vitamins and most minerals, if taken in excess, will simply be expunged from your body. Those four are not.
With those, I'd be pretty careful to have my healthcare team monitor your base level, and any supplemental amounts you might be tempted to take.
400 IU is 100% So 400% would be 1600 IU. So you are still well below the Tolerable Upper Intake Level (for a healthy adult) which is set at 4000 IU.
Hope this helps Becky

Thanks, Becky. My tracker says I should have 100- 150%, and I'm wondering of what. I generally go way over (400+) and that's from the D that's been added to everything else. I don't take a Vitamin D supplement.
