30,000 IU is a lot. From what I've read, too much. Are you sure about what you're doing?
“Are you sure about what you’re doing?”
It hasn’t bothered me at all. It compares to what you get from spending an hour and a half in the sun with no shirt, it’s not that much. Mind you, this isn’t a recommendation for anyone else. I think many thousands more units would be necessary to reach toxic levels. I’ve even heard figures like a million units, but I won’t be testing that. Thanks!
