i loaded up on a bottle of costco vitamins and d3 supplement before we went on lockdown. There seems to be something in the multivitamins that i'm allergic to in high quantities, i.e. after taking them for 3-4 days straight I'll start getting hives. I reduced consumption to 1 mv tablet every 3 days and no problems so far. I'll probably increase d3 intake to 1 2000iu tablet per day and see how it goes.
Weird that it took a few days for the allergy to kick in. Do you get hives from other stuff?
I had a bad allergic reaction recently to wine (which was never a problem before), that started as bad hives and progressed to me nearly fainting. Doctor tested me as positive for a grape allergy, but negative to the shellfish allergy that caused hives as a kid.
Anyhow, all of that is to say that the doctor prescribed me an epipen, because apparently it's possible to experience anaphalaxis without having breathing issues. And full-body hives is one sign of that. The near-fainting I experienced was likely due to low-blood pressure, which is another symptom. So just be careful. I had always thought hives weren't a big deal (other than being extremely annoying), but I'm definitely going to take them more seriously from here on out.
