I remember something about Vitamin C preventing viruses from multiplying, Zinc preventing viruses from breaking through your cell walls or something, I'm trying to talk my dad and uncle some sense. I want to go visit my Grandmother (who knows this is all bullshit too and takes her vitamins) but they don't want me too. My uncle even texted me that "she thinks taking all her vitamins will stop her from getting sick" I remember reading exactly how certain vitamins interact and prevent you from getting sick and was wondering if anyone knew that document?

Thank you.
