Study Arms (2)
Bifidobacterium Infantis NLS Super Strain
ACTIVE COMPARATORParticipants in the probiotic period will take two capsules of Bifidobacterium infantis NLS super strain (Natren LIFE START®2) three times per day for three weeks. Each capsule contains 2 x 10\^9 colony-forming units (CFU) of Bifidobacterium infantis NLS super strain, for a total daily dose of 12 X 10\^9 CFU. The probiotic will be kept refrigerated during transportation and throughout the study period.
Placebo
PLACEBO COMPARATORParticipants in the placebo period will take two capsules of placebo three times per day for three weeks. The placebo capsules contain rice flour, hydroxypropyl and methylcellulose. The placebo will be kept refrigerated during transportation and throughout the study period.
Interventions
2 capsules, 3 times per day, for daily total of 12x10\^9 CFU Bifidobacterium infantis NLS super strain
2 capsules, 3 times per day, containing rice flour, hydroxypropyl and methylcellulose
Eligibility Criteria
You may qualify if:

- Consuming a gluten-free diet for at least 2 years
- Persistent gastrointestinal symptoms: global GSRS questionnaires ≥2 or ≥ 3 points for any of the 5 sub-dimensions
- Signature of informed consent
You may not qualify if:
- Patients not interested or unable to comply with questionnaires and collection of samples of blood, feces, and urine
- Complicated celiac disease (refractory, ulcerative jejunoileitis, lymphoma)
- Concomitant pathologies that are uncompensated or untreated (Type I or II diabetes mellitus, hyperthyroidism, hypothyroidism, diarrhea due to bile salts, pancreatic insufficiency, bacterial overgrowth)
- Consumption within the 2 weeks prior to study enrollment of medication that interferes with bowel functioning (antibiotics, NSAIDs, laxatives, metformin, opiates, anticholinergics \[atropine, antidepressants, neuroleptics, antipsychotics, antiparkinsonians\], anticonvulsants, antihistamines, antihypertensives \[calcium antagonists, clonidine, diuretics, metal ions (aluminum), antacids, sucralfate, barium sulfate, bismuth, calcium, iron, heavy metals (arsenic, lead, mercury)\], resins (cholestyramine), or any other medication deemed relevant by the investigator).
- Women that are pregnant or may become pregnant during the study
