I wouldn’t beat yourself up about the enzyme products; I’ve taken them throughout my treatment and do personally think that they bring a benefit. They help heal leaky gut, break down the food fermenting in your gut. They also destroy biofilms (supposedly). It helps you get more energy out of the food you eat, which allows you to heal faster.
I take one called pro-gest as a comparison.
An alternative (I bet you know this) is to take bitters which cause the body to produce its own enzymes.
