Use caution – aka ascorbic acid. I was taking 1000-3000mg/day. No wonder I was having such a hard time with my outbreaks in the beginning. You need Vitamin C, just be cautious and take an antacid a bit later. Please read my section on a low acid diet to understand this in more detail.
I truly believe that bacteria thrive in basic environments and viruses thrive in acidic environments. This is why our bodies are able to bounce back and forth between the two states. I believe Linus Pauling saw great results in patients with bad bacterial infections, he was simply increasing their blood acidity. However, mega dosing on Vitamin C will only cause you massive amounts of herpes pain and certainly no cure.
