Hello David,
A man I know, the one I made my case study on, is dealing with chronic diarrhea since August. He has been taking 6000mg of vitamin C for the past 9 months following a recommendation on a web site (cancer prevention and care). The research I have done on internet indicate an upper limit of 2000 mg a day. Could this high dosage cause irritation? Should I recommend to stop or decrease the amount, and if yes for how long? He had stoped once for 3 days but did not notice any improvement, but maybe it was not long enough for the gut to heal.
Thank you,
Anne
