Inclusion Criteria:

  • Male or female between 18-65 years of age (inclusive)

  • Subjects currently taking or taken within 28 days of randomization a concomitant medication that causes constipation which in the Principle Investigator's opinion may impact the study results.
  • Any non-gastrointestinal disease/complication that, in the investigator's opinion, may affect subject safety or confound the evaluation of the study endpoints
  • Immunodeficiency (i.e. HIV positive, rheumatoid arthritis, history of organ transplant)
  • Clinically significant abnormal laboratory results at screening (e.g. AST and/or ALT > 2 x ULN, and/or bilirubin > 2 x ULN; serum creatinine > 1.5 x ULN; hemoglobin < 140 g/L for males and < 123 g/L for females)
  • Abdominal or perineal surgery within 6 months of randomization
  • Subjects who plan on engaging in anal intercourse during the run-in or treatment periods of the trial. Enemas are not allowed within 7 days of randomization or throughout the trial.
  • Participation in a clinical research trial within 30 days prior to randomization or participation in a clinical trial researching a probiotic within 60 days prior to randomization
  • Currently taking anti-psychotic medication
  • Allergy or sensitivity to study supplement ingredients
  • Use of pre- and probiotics within 8 weeks prior to randomization
  • Alcohol abuse (>2 standard alcoholic drinks per day) or drug abuse within the past 6 months
  • Individuals who are cognitively impaired and/or who are unable to give informed consent.
  • Any other condition which in the Investigator's opinion may adversely affect the subject's ability to complete the study or its measures or which may pose significant risk to the subject
