Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
The nutritional intervention is a Polyphenol Rich Sugarcane Extract PRSE. Participants are expected to consume two capsules a day, one in the evening and one at night at approximately the same time each day (± 60 mins). PRSE’s can be consumed with or without food and on an empty stomach. Each capsule contains 250 mg of PRSE.

Participants will receive either the control sample (placebo) or the PRSE sample for a duration of 3 months, followed by the reversal of conditions for the subsequent 3 months. The samples will be sent to participants via mail at the commencement of each phase. The nutritional intervention is to be completed (consumed) in the participants own setting (i.e. home/work).

There is no washout period between phases.

Daily adherence will be tracked through a short emailed online questionnaire, where participants record their daily intake. Additionally, at the end of each month, participants will report the number of capsules remaining.

Comparator / control treatment
Maltodextrin will be used as the placebo, which will be colour matched to the PRSE and loaded in the identical gel casing as the PRSE product.

Treatment
Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
Participants will undergo random assignment to one of two groups, with group allocation concealed. A random, unique three-character alphanumeric code will be assigned by the manufacturer to each of the group allocations. This approach ensures that study investigators, statisticians, and participants remain blinded to the group allocation.
Methods used to generate the sequence in which subjects will be randomised (sequence generation)

Participants will be assigned through simple randomisation using a computer-generated randomisation table created before the recruitment of participants. Allocation will follow the order of recruitment dates, placing participants into one of two groups.

Summary
Brief summary
PRSE’s naturally occur in plant derived foods and beverages and holds great potential for enhancing human health. However, further research is required to understand the broad-spectrum of effects of PRSE’s by assessing its potential short and long-term benefits to general well-being.

This study is a 6 month double-blinded randomised controlled cross over trial. Participants will receive either the control sample (placebo) or the PRSE sample for a duration of 3 months, followed by the reversal of conditions for the subsequent 3 months. The nutritional intervention is to be completed in the participants own setting (i.e. home/work).

This study aims to investigate the prebiotic effects of PRSE, as well as the effects on inflammation and key blood biomarkers, including HbA1c, C-reactive protein, and triglycerides/omega-3 status. The study will also explore the influence of PRSE on general mood and well-being.
