Vit.C lowers cortisol and raise adrenaline?

I've read on another forum weeks back that vit.C lowers cortisol and raises (or help raising) adrenaline. I thought vit.C helps adrenals ~ raises cortisol and it is anti inflammatory and stuff...

Anyone knows something about that/ are these remarks true?
If they are true - than a person with low cortisol (low production of adrenal cortex) should not take it? Like wiredgen or myself.
And should supplement directly with cortex extract but no C? Like wiredgen did.

Or Am I simplyfing too much?

Thanks
