So it's safe to say that the zinc, bitters, Vit B and TMG with each meal would take care of any bugs or viruses that got into the tummy and/or gut?
I'm thinking of food poisoning and/or diseases.
Maintaining stomach acid will help to control pathogens in the stomach.
For food poisoning though I recommend downing as much kefir as you can. The good bacteria will overwhelm the bad bacteria quickly clearing up symptoms.
