Sounds like you are doing good. I don't currently take enzymes and haven't for years. I do take some probiotics if I have eaten something that has upset my stomach. I suppose a raw apple would be just a beneficial.
I don't know what they make enzymes out of. The last one I took were about 10 years ago from a company selling them.
I guess I am trying to avoid eating the things that would require me to even take them.
Good thing about your skin and iodine. I have been trying to cut out all skin products too.
