  • Self-reported or suspected history of lactose malabsorption or lactose intolerance

You may not qualify if:

  • History of prior gastrointestinal surgery
  • Self-reported history of any chronic gastrointestinal disease (examples include gastroesophageal reflux disease, celiac disease, Crohn's disease, ulcerative colitis, pancreatitis)
  • Self-reported history of endocrine or metabolic disease that may impact gastrointestinal or colonic function (examples include hyper/hypothyroidism, diabetes, etc)
