>> DMSA, ALA and Hydrogen Peroxide being taken together orally?
You don't want to take them together that is for sure.
IMO a cheap ozonator is better because H2O2 (Hydrogen-Peroxid)
always leaves some H in your gut that isn't always a great thing.
But I see no issue if you want to use both, if it was me I would time my O3 - Ozone
treatment 30-40 prior to my next dose of chelators.
But I haven't done this so dont take it as saying it is save...
