Allergies, especially food allergies (runny nose after eating), itchiness, eczema, brain fog are all symptoms of candida mostly because of the associated leaky gut. There is no silver bullet in getting rid of candida. About half of the symptoms are caused by aldehyde toxin from candida and the the other half is the cascade of immune stress caused by the leaky gut.
For liver support (to help neutralize toxins on the liver) take molybdenum 500 mcg 2 times a day. Also take milk thistle extract 2 X 500 mg. 3 times a day.
For adrenal support (if you have allergies your adrenals are exhausted) take 1 gram Vitamin C (sustained release) every 4 hours while awake. Take pantothentic acid 500 mg. 3 or 4 times a day (this one is crucial). Ashwagandha and holy basil extract are also helpful for adrenal support.
But the thing that helped most with my leaky gut is taking COLOSTRUM powder. Take 2 heaping teaspoons every 12 hours. The pill form is too expensive. Get the powder. An excellent product which is a bargain considering the quantity you get is a kilogram (2.2 POUNDS!) for under $100!
Now I got over my candida on a ultra low carb diet (no grains, fruit or legumes, and of course no sugars) but I now believe it is possible to take some monosaccharide Sugar (dextrose which is glucose) because it is absorbed in the upper intestines and won't reach the bowel where the main yeast infection exists. Don't go overboard but you can sweeten some herb tea with a couple or three teaspoons of glucose and drink that. It will prevent low blood Sugar and there is research showing that the immune system especially neutrophils require Sugar (glucose) to function. You can buy a 10 pound jar of dextrose for under $20:
