This is an old post but I am answering in case someone does a search on it. My son gets very depressed from candida so each time we increase the dose of the various things such as kraut, oil of oregano, etc. that we are using to control the candida he gets depressed for a few days UNLESS he takes enough vitamin c to constantly keep himself near bowel tolerance. Vitamin C obliterates the Depression that the candida toxins give him. Some days he has to take 50 or 60 grams spread out through the day. So although the vitamin C doesn't do anything to kill the candida, it makes it possible for him to treat the candida and still live his normal life at the same time.
