Description of intervention(s) / exposure
164 patients will be randomised to one of 4 groups (1:1:1:1) to receive:

- Bioceuticals Prebiome Fibre only (5g powder/twice per day) (Group A) for 16 weeks;

We advise to mix this product into food such as a smoothie, yoghurt, cereal, porridge or mashed fruit. Please also drink 250ml of water close to the same time as taking the Prebiome Fibre supplement. Please make sure that you drink at least 1500ml of fluid per day of which 500 ml is water.

- Blackmores Grapeseed Forte only (2 tablets/day) (Group B) for 16 weeks;

This is to be taken by participants at 2 Tablets once per day with food. This is the same instructions as what stated on the bottle.

- Prebiome Fibre (5g powder/twice per day) and Blackmores Grapeseed Forte (2 tablets/day) (Group C) for 16 weeks;

We advise to mix Prebiome Fibre into food such as a smoothie, yoghurt, cereal, porridge or mashed fruit. Please also drink 250ml of water close to the same time as taking the Prebiome Fibre supplement. Please make sure that you drink at least 1500ml of fluid per day of which 500 ml is water.
Grapeseed Forte is to be taken by participants at 2 Tablets once per day with food. This is the same instructions as what stated on the bottle.



Participants will be contacted by the research team to check how they are progressing and they will request that participants are to take a photograph with their mobile phone or camera of the packaging of the supplement to see how much is left and send to the research team, so participants should not throw out any empty jars. This is how monitoring will take place.

Outcomes
Primary outcome [1] 325944 0
The primary outcome is a change in high sensitivity C Reactive Protein (CRP), an inflammatory biomarker, between pre (Baseline) and post treatment. Blood serum samples from participants will be taken to determine CRP at baseline and at post treatment time points.

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)
Allocation is not concealed
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
Participants will be allocated to treatments by stratified block randomisation. Because we expect both individual participants and partnered people (e.g. a married couple) to be recruited, randomisation schedules will be created separately for individuals and couples. We will use blocks of size 4 or 8, randomly determined. In the couples stratum, the unit of randomisation is the couple and both members of the couple will be allocated to the same treatment. Randomisation schedules will be created by an independent statistician.

Efficacy
Statistical methods / analysis
In order to find the supplement1 * supplement 2 interaction in the decrease in CRP with 80% power, we would require 32 people in each group. However, since we are expecting that 25% of our participants will be part of a couple, we have to increase our sample size based on the effective N, accounting for clustering.
Assuming a within-cluster correlation of 0.1, the effective sample size is: neff=n / (1 + (n-1) icc)
Neff = = 32 / (1+(1)*.1) = 29
So, to achieve 32 in each group, then, we should recruit 3 more in each group, for N=35 or 140 in total.
Finally, to account for 15% attrition, a total of 164 people should be recruited
Sample size statement: We hypothesize that those in the group receiving both supplements will show larger
decreases in CRP multiplicatively than those in the other groups. In order to detect the Supplement 1 * Supplement 2 interaction, assuming 80% power and alpha=0.05, we would require 32 in each group (128 participants in total). However, because we intend to recruit couples as well as single people and account for expected attrition over the trial, we must increase the sample size. Assuming a within-couple correlation of 0.10 and 25% of the sample will be couples,
we would need to recruit a total of 140 participants. To account for expected 15% attrition, we will recruit a total of 164 people.

Summary
Brief summary
This study is a randomised controlled open labelled pilot trial. The research study aims to explore the effect of fibre and antioxidant supplementation on values of inflammation found in blood and the microbiome on older adults living in the community aged 60-70 years old.
This pilot trial is significant because the researchers hope the results of this trial will provide initial evidence of the effect of nutritional supplements on the health status of older Australians especially in relation to nutrition, inflammation and frailty.
