Researchers at the Bioeconomy Science Institute Maiangi Taiao are looking for healthy adults aged 18–50 to take part in a pilot nutrition research study.
Blackcurrants contain a naturally occurring compound called sarmentosin. Our previous research suggests sarmentosin may play a role in blackcurrants' effects on brain function, including alertness and reaction time.
We now want to understand what happens to sarmentosin once it enters the body – specifically how it is absorbed, metabolised and excreted.
In this pilot study, we will measure sarmentosin and the compounds it breaks down into in blood, urine, and faecal samples after participants consume a blackcurrant extract. The findings will help us design a larger follow-on study.
What does the study involve?
The study takes place over three days and involves one full study day and two shorter follow-up visits.
You will be asked to:
- Drink a blackcurrant extract containing sarmentosin
- Provide blood, urine and faecal samples at different times
- Complete short questionnaires about how you feel
- Follow some dietary and fasting instructions before and during the study
The main study day includes several blood samples and lasts approximately 12 hours, with follow-up visits at 24 and 48 hours.
Who can take part?
You may be eligible if you:
- Are a healthy adult aged 18–50
- Do not smoke or vape
- Are not pregnant or breastfeeding
- Are not allergic or intolerant to blackcurrants
- Are comfortable providing blood, urine and faecal samples
Other eligibility criteria apply and will be discussed with you by the research team.
Receive up to $220 for taking part
Participants who complete the screening and all study visits will receive up to $220 cash in recognition of their time and contribution.
Where is the study?
The study will take place at Bioeconomy Science Institute research facility in Auckland.
