Nugget

Thanks, @spinyand @xxx! I went from 23 to 124 ng/mL in 29 days, and my doc said I had to stop supplementing. I wouldn't mind keeping around 80. Maybe I'll go back to 4K/day and re-test. I just don't want to have to test every 30 days forever.

Is there a way to calculate a personal vit D maintenance dose based on 25(OH)D levels and supplementation? I am guessing it is a ratio involving number of days on the regimen, total quantity of vit D taken during that period, and change in 25(OH)D, but I can't wrap my mind around it. I can share numbers if you know what on earth I'm talking about (BTW: I am ECH. Did not feel like I got benefit from the regimen during my last cycle, but my baseline vit D is low anyway, so I'm willing to try supplementing to see if it pushes out my next cycle!)
