Thank you for your interest in Atrantil! Not all people using Atrantil experience a die-off reaction. If you do not experience die off, Atrantil is likely working! However, a small percentage of people may experience temporary, cold like symptoms such as; muscle ache/fatigue, runny nose, stomach ache/cramps, fatigue, nausea, etc. OR increased digestive symptoms such as diarrhea, constipation, or bloating after taking Atrantil. This is generally not a reaction to Atrantil, but a reaction to the Archaeabacteria dying off and releasing endotoxins that behave as a mild irritant. Die-off should be seen as a positive sign, indicating that Atrantil is working, SIBO is the correct diagnosis, it will end soon and run its course, and that you are close to relief form SIBO issues!  In most cases of Die-Off, taking one Aspirin or Ibuprofen will bring relief from these symptoms. Please let us know if you have any further questions. We are always happy to help!


Sincerely, 

Support Team
