The vit c/sepsis connection has been studied awhile...and if I were in sepsis situation, I would demand it.
A couple years ago THIS came out...

Vitamin C in high doses is good for many things. But few docs will tell their patients that.
If I remember right Linus Pauling used to take 20,000mg or some such of Vit C every day. Most people would get stomach cramps and diarrhea at those dose but Linus apparently built up tolerance. It could be 10,000mg I am not sure.
Because it is cheap. I'm sure they will be more interested if they can change the label and charge a 2000% markup.
