• Microcrystalline cellulose
• Magnesium stearate
• Has any significant acute or chronic coexisting health conditions that would prevent the Participant from fulfilling the study requirements, put the Participant at risk or would confound the interpretation of the study results as judged by the Investigator on the basis of medical history.

• Restrictions during study participation: Participants must refrain from initiating or using any of the following prohibited supplements during the study period include:
• Postbiotics
