Efficacy
Statistical methods / analysis
A sample size of 30 patients was calculated based on the following assumptions:
a) To detect a difference of 0.78% (SD=0.1) in Lactulose levels (Leaky gut test: Lactulose/Mannitol change detected in Gut Relief Study)submitted before and after the active treatment with >90% power and 95% confidence;
b) to account for 20% drop-out or non-attendance at all appointments.

Analysis
Analyses will be performed using SPSS (PASW version 18). Statistical significance will be set at p<0.05. This is a pilot study and differences within the group (pre- and post-intervention) will be analysed with repeated measures ANOVA at 8 and 12 weeks compared to baseline at 4 weeks. The first 3-4 weeks will serve as run-in control phase for comparative analysis of weeks 0 and 4 for questionnaires. Leaky gut analysis at 12 weeks will be compared to baseline (0-4 weeks).

Summary
Brief summary
Gastrointestinal problems in the lower gastrointestinal tract can manifest as irritable bowel symptoms. The Broth & Co Beef Bone Broth Powder contains a nutrient rich mix of amino acids, minerals, collagen, glucosamine and chondroitin, which have been shown to be beneficial for the gastrointestinal system. In this pilot single-arm pre-post study of 12 weeks duration we aim to investigate the effect of the Broth&Co Beef Bone Broth Powder on gastrointestinal disturbances in Australian adults.
