I've been taking vitamin D for years but whenever I increase, say for illness or winter blues I get bloated and sneeze alot, I use to get achy bones too, but K2 seems to help with that. Is this something that will pass or should I just stick to 1000 iu. I've recently increased to 5000 Iu for a cold virus in hopes of getting rid of it. But now I'm bloated, small baby bump type bloat and sneezing alot.. I'm starting to think im allergic, my mom was allergic to the sun, maybe it was the vitamin.. just curious.. thanks for input all is appreciated..
