I would only use one at a time and not both at same time. These products will not cure your overgrowth by themselves. Basically you’ll need to take digestive enzymes long term to find any benefit in them, I’ve been on them for about 3 years myself. The main thing they do is help break down the food you eat while slowly eroding the fence candida creates to protect itself.
I take a different digestive enzyme called progest which will support your digestion more than these products because it contains ox bile and some HCL. It also contains some different enzymes.
There are a variety of enzyme products out there with a variety of different prices.
