Welcome!
To my knowledge, there’s no field specifically designed to add gut flora. (There’s a limitation that prevents energetic fields from making something material without having the physical raw materials in place first. For example, the muscle growth fields can’t grow muscle for us if our bodies don’t have the physical raw materials in place needed to grow those muscles, you see?)
There are fields which promote an ideal environment for the (existing or supplemental) gut Flora to grow:
- Intestine Healing and Regeneration
- New release - The Intestinal Cleanser
- The Iron Gullet (Gastrointestinal Inflammation Help)
- IBS field(patreon)
just to name a few.
