I think both MMS and Zeta Aid go hand in hand. One dissolves biofilms, the other kill the bacteria.Thanks for your terrific, helpful response, really appreciate it! I've been taking Zeta Potential for over a year now, but only once a day. But your post makes me think I have to up it to 3 times, as he says. I just saw my cardiologist last week, to review my treadmill and other tests, and the good news is I have no blockages (in my late 60s). Not so good news is I have one heart valve that's weaker than it should be but no need to do anything with it for now, just monitor it. And afib is still there. I will look into chlorine dioxide. Thanks again!
