Our researchers at the Bioeconomy Science Institute Maiangi Taiao are inviting healthy women to take part in a research study exploring how the gut microbiome processes food at different stages of life, particularly before and after menopause.
This study focuses on two groups — women aged 30–40 (pre-menopause) and 55–65 (post-menopause) — to better understand how gut bacteria ferment food and how this may influence health and wellbeing.
As part of this study, our research team are asking volunteers to donate a single stool (faeces) sample for laboratory research. The process is simple, using a hygienic collection kit. Full instructions are provided.
By taking part, you’ll be contributing to research that could support the development of foods designed to promote health during and after menopause.
What's involved
Participation is simple and low impact. If eligible, you will:
- Complete a short health questionnaire
- Provide one stool sample, Palmerston North
- Use a simple at-home collection kit that fits into the toilet bowl, with clear step-by-step instructions
The process is designed to be straightforward, hygienic, and easy to follow.
Participants will receive a $30 supermarket voucher as a thank you.
