How high?

  Around 10g a day can cause kidney stones in some people.

    Research more about it : there's absolutely no correlation.

  I could tell you but I'd rather you read about it and then make your own opinion. You will find anything and everything about vitamin C on the web : there's a lot of success stories of people that tried it and then some people that caution about some experiments in vitro that had some potential harmful effect. But I didn't find (doesn't mean it doesn't exist) a single story about someone that had a problem with it. All the negativity is by people that didn't try.
