Description of intervention(s) / exposure
Arm 1: Inferrin™: 120mg of Inferrin™ (equal to 50mg of lactoferrin) (total of 240mg daily) in capsule form. InferrinT™ is a proprietary microencapsulated form of lactoferrin. Participants randomised to this group will be instructed intake 120mg Inferrin™ twice daily with food and 250mL water for 56 days.

Study design
Purpose of the study
Treatment
Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
The potential participants are screened by the investigator for inclusion in the study. The eligible participants are enrolled by investigator and provided with a "Numbered Container" that is identical to all other containers and contains the same information on the label, except for the number. The investigator is blinded to the product randomized with the
numbered containers labelled prior to delivery to investigational site. Product allocated as participants are enrolled in sequential order
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
The initial randomisation code will be generated by Random Allocation Software and patients allocated to one of the two groups at time of enrolment.
Masking / blinding
Blinded (masking used)

Summary
Brief summary
Approximately 120 adult male and female participants aged over 18 will be recruited from databases and public media outlets. Following preliminary screening via telephone, if eligible, potential participants will attend the clinic for an information session and will be requested to provide their consent for inclusion in the trial. Consenting potential participants will undergo a health assessment including lifestyle, current medications, weight and height assessment, blood pressure, heart rate, IBS questionnaires and medical history; this data will be used for the comprehensive screening and to provide contextual data for the study. A blood test will also be carried out.

Participants will take the allocated product daily for 56 days attend the study site at day 28 for a progress assessment. At this assessment, all baseline tests will be administered including the blood test.

On day 56, the participants will attend the study site and all baseline tests will be administered and blood samples will be collected. A final exit interview will also be undertaken.
