SF722 undecenoic acid is a great long term antifungal that is pretty powerful and you likely will notice major improvement after taking it.
Candidase is an enzyme product and there are other superior enzyme products when compared to this one; I take one called pro-gest for instance and this has worked great for me.
You can take probiotics and antifungals at different times and this won’t cancel them out.
I would get tested for heavy metal toxicity before you start chelation. Also, you should have a neutral pH before chelation, otherwise it will extract too many beneficial minerals from the body. I am going to start chelation within the next few months and should be interesting.
