You are NOT alone! I've tried every form and dose of D3 to no avail: within 3 hours of taking it, my BP spikes so badly I can actually FEEL it! And when I check, using my cuff, it's always unbelievably high. Within 24 hours it's gone and I'm back to normal, but it's scary.

I have tried it over and over again, taking it with food, without food, early, late, with calcium, without it, before exercise, afterward, and it's always the same result. As if I were having an allergic reaction or something. I'm wondering if it's genetic, because my son has a similar reaction. We can't even eat any food that has D3 added to it.

I've never been tested, but my annual physical is coming up in March and I'm definitely asking for it. Somehow it wouldn't surprise me to learn that my score is high, though how I don't know. Still, there has to be something going on here.
