blastobegone: Are you kidding me? Seriously? Unless you understand biochemistry you won't even understand what I'm on about LOL!
How I explain? Genetic and immune differences possible yes. However it all comes down to a level of inflammation in a body as well. But with general ppl it's always a mix of issues not just a parasite issue on it's own. We are talking about hormone dysregulation/sensitivity, amount of cell damage, etc.
Supporting your immune system with vitamin C is one thing. Building up your immune system with it is another I guess you are talking about the 'default state'? Won't work unless you get rid of a last parasite or start activating what they inhibit via specific interleukins.
