KIWIFRUIT TRIAL

 Can kiwifruit extracts prevent constipation and gut discomfort?

The University of Auckland Human Nutrition Unit is inviting

people who suffer from Constipation to take part in a kiwifruit extracts study

What are the aims of the study?

The aim of the research is to investigate whether an encapsulated extract of kiwifruit can help to alleviate constipation, and symptoms such as stomach pain, in people who suffer from this condition.

Where will the study take place?

The study will take place at the Human Nutrition Unit (HNU) which is a purpose designed human volunteer facility located in Mt Eden (approx 3km from the CBD). Easy and free on street parking

Who designed the study?

This study was designed by research staff at the University of Auckland Human Nutrition Unit (HNU), in association with New Zealand Extracts Ltd, a company who manufacture nutritional supplement ingredients within New Zealand.

What does the study involve?

The study is open to men and women aged 20-65 years who are well but have constipation. You must be able to travel to HNU in Mt Eden for a few visits with the study team.

The study will continue for 9 weeks in total, comprising two intervention arms each of 3 weeks plus a break in the middle (3 weeks study – 3 weeks break – 3 weeks study). For the two intervention arms, you will be given capsules containing either the active test product (kiwifruit extract) or a placebo product (an inactive compound), and record gut discomfort and bowel habits. During this time, you will only need to visit the HNU four times (short visits) in order to pick up the capsules and to drop off your forms.

Will I get paid for taking part?

A gratuity and travel expenses (e.g. bus fare, petrol) will be paid for participation.


If you are interested in taking part we would be pleased to discuss the study in more detail.
