This trial will investigate the potential of a bioactive peptide to reduce symptoms of digestive discomfort in a generally healthy elderly population. Participants will consume the bioactive peptide for 12 weeks and various measures indicating an improvement in health and well being will be taken throughout the trial. It is believed that consumption of the study product will reduce the severity of digestive discomfort, reduce chronic inflammation, improve blood glucose metabolism and improve physical performance.

Forty subjects aged between 65 and 75 with self-reported symptoms of digestive discomfort will be randomised. Subjects will be randomised to receive either the Bioactive peptide or placebo for a total of 12 weeks.

Subjects will undergo an initial phone screen and will be asked questions regarding their age and their symptoms of digestive discomfort. Eligible subjects will be scheduled for a screening visit. The study will involve 5 visits over a 13 to 16 week period.

At the screening visit (Visit 1) the inclusion and exclusion criteria will be reviewed and the overall details of the study will be explained and informed consent obtained. Vitals and Medical history, demographic data and concomitant medication will be recorded.

Subjects will be asked questions relating to their digestive symptoms, including symptoms of abdominal pain, discomfort, bloating and flatulence. Subjects will complete the Digestive Symptom Frequency Questionnaire (DSFQ), the International Physical Activity Questionnaire (IPAQ) and the Mini-mental State Exam (MMSE) will be administered. The Fried Frailty score will be completed and the Short Physical Performance Battery (SPPB) test will be performed. A fasting blood sample (9mls) will be collected and haematology, biochemistry, glucose and blood lipids will be measured.

Subjects will be provided with a stool collection kit and instructions for collecting and storing. Subjects will collect a stool sample at home, within 24 hours of their next visit and bring it to the clinic at their next visit.

If the subject meets the eligibility criteria, they will be invited to participate in the study and will be given an appointment to return to the study site within 4 weeks for their baseline/week 0 visit.

Subjects will attend visit 2 fasting. The inclusion and exclusion criteria will be reviewed and eligibility for study entry confirmed. An Oral Glucose Tolerance Test will be performed. Haematology, biochemistry and blood lipids will also be measured.

A urine sample will be collected and also stored frozen for analysis of metabolites.

Vitals, anthropometric measurements, concomitant medication and any adverse events will be recorded and The Short Physical Performance Battery (SPPB) test will be performed.

Subjects will complete the Digestive Symptom Frequency Questionnaire and the hand-grip and chair-stand tests will be performed. A DEXA scan will be performed and muscle and fat mass recorded.

Subjects will be randomized to receive the Bioactive peptide or placebo and receive a 4 week supply of product and instructions for dosing. Subjects will be provided with a stool collection kit and instructions for collecting and storing. Subjects will collect a stool sample at home, within 24 hours of their next visit and bring it to the clinic at their next visit.

Subjects will return for visits at week 4, week 8 and week 12.

A similar regimen will be followed for visits at week 4, week 8 and week 12.
