  • Individuals with childbearing potential must agree that they and/or their partner will practice birth control upon enrollment and throughout the study (abstinence, tubal ligation, vasectomy, progestin arm implant, intrauterine device, oral contraceptives, progestin injection, emergency contraception, male condoms, diaphragm, cervical cap, female condom, sponge, withdrawal method, spermicides, rhythm tracking, etc.)

  • Have a known sensitivity, intolerability, or allergy to any of the study products or their excipients, or any of the rescue medications.
  • Received a vaccine for COVID-19 in the 2 weeks prior to screening or during the study period, current COVID-19 infections, or currently have the post COVID-19 condition as defined by World Health Organization (WHO) (i.e., individuals with a history of probable or confirmed SARS-CoV-2 infection, usually 3 months from the onset of COVID-19 with symptoms that last for at least 2 months and cannot be explained by an alternative diagnosis).
  • Participants will be terminated if receiving the COVID-19 vaccination during the study trial
  • Participants with diagnosed type I or type II diabetes.
  • Having a history of heart disease, uncontrolled high blood pressure (≥140 mmHg systolic or ≥90 mmHg diastolic), renal or hepatic impairment/disease or dysfunction, major affective disorders, unstable thyroid disease, immune disorders and/or immunocompromised (e.g. HIV/AIDS), cognitive impairment, neurological condition, or neurological disease, psychiatric disorder that required hospitalization in the past year, cancer (except localized skin cancer without metastases or in situ cervical cancer) within 5 years prior to the screening visit. Outside of these highlighted outcomes, study participants can be excluded based upon an evaluation by research staff and consultation with the medical director if the presence of any medical condition or disorder may either put the potential participant at risk because of participation in the study, or influences the results or the potential participant's ability to participate in the study.
  • Major surgery in 3 months prior to screening or planned major surgery during the course of the study.
  • Participant has an abnormality or obstruction of the gastrointestinal tract precluding swallowing (e.g. dysphagia) and digestions (e.g. known intestinal malabsorption, celiac disease, inflammatory bowel disease, chronic pancreatitis, steatorrhea).
  • Participant, over the previous 12 months, has a history of regular alcohol use that exceeds more than 2 standard alcoholic drinks per day or more than 10 drinks per week prior to screening.
  • Receipt or use of test product(s) in another research study within 28 days prior to baseline or longer if the previous test product is deemed by the investigator to have lasting effects that might influence the eligibility criteria or outcomes of current study.
