Enzymes improve overall digestion, hence better assimilation and less food for Candida. Protease also breaks down the yeast's cell wall so it cleans the intestines when taken on an empty stomach.
The only drawback is sensitivity, so if you your gut is somehow damage you should take it slowly. I found that taking l-glutamine along with the enzymes help me. Be careful with l-glutamine cause while your body gets used to it you may get a little hypoglycemia.
