Hey Dcd - hope you are making some progress with the IBS-C
it was nagging in the back of my mind how the Atrantil product was supposed to work - so i looked it up
google had this to say

Atrantil is a nutraceutical supplement that uses natural botanical extracts to relieve bloating, constipation, and abdominal discomfort. It works by removing gas-producing bacteria from the gut.
How it works
1. Calms the small bowel
Peppermint leaf extract calms the small bowel, allowing the other botanicals to work more effectively.
2. Soaks up hydrogen
Flavonoids from quebracho extract soak up hydrogen, creating an environment that's unfriendly for archaebacteria.
3. Stops methane production
A natural antibacterial from conker tree extract binds to the reductase enzyme in the weakened archaebacteria, stopping methane production.
seems to have a double pronged attack on shutting down archaea - so i thought i would pass it on - in case its of any help
