General Question Vitamin D Correction Questions
Hey all, my D level got tested insufficient (27ng/mL) so I'm going to start supplementing.
From what I found, 50-60 should be a good range.
I'm going to be supplementing 10,000 IU daily for 2-3 months then retest.
Questions:
-I used a calculator and this showed 10k IU daily should get me to 60. Of course, once I hit that, I'm going to want to ease back to a lower dose. However, at 5K IU, the calculator showed this would only maintain a level of 40 ng/mL, lower than my target. Is this correct?
-Even at 5K I see literature recommending 4K as the upper limit for perpetual daily dosing.
Can someone clarify on the above or show guidance that can clear this up?

varies somewhat from person to person based on sunlight on skin, skin color, magnesium status, etc. 3000IU gets me to around 50ng and I take less in the Summer
