I did some reading on this too. It's not a good idea to take mega doses of vitamin C if you have any trouble with your kidneys because it taxes your kidneys when it is being processed by your body. I'd also think twice about using vit C tabs internally as most of them are chewable and have sugar in them and sugar vaginally leads to yeast infections.
