Digestive enzymes are a great addon to a candida diet since the gut profoundly need them in digestion.
The other benefits you get from digestive enzymes is that some of the enzyme strains tear down the outer wall on candidarhizoids which protects them, after that it's easier for the anti-fungals to carry out their duties (whether it is GSE, Diflucan or something else that goes into the bloodstream).
The last thing you got to know about digestive enzymes is "when" you'll take them.
If you take them on an empty stomach they aid the gut walls and in the bloodstream and if you take them with meals they mostly help in digesting the food, processing the carbs/glucose before candida gets to it.
