If you’re experiencing stomach problems, you could help health research.

Thank you for your interest in RDC Clinical’s new research study into the effectiveness of a commercially available Kiwi fruit concentration powder. This freeze-dried product contains a number of natural compounds believed to bring relief from gastrointestinal discomfort including bloating, abdominal pain, constipation and diarrhoea.

You could assist gastrointestinal research & learn more about your lifestyle.

Although you’ll only qualify for this study if you’re currently experiencing stomach issues, so we can measure any relief you feel, it’s important to know the Kiwi’s powerful enzymes, antioxidants and fibre may help other aspects of our health. For example, the antioxidant Lutein has been shown to improve Macular Pigment Optical Density, a leading cause of blindness in the western world.

In addition to assisting the study, you’ll also gain valuable insight to your general health and lifestyle.

If you would like to play your part in this important research, you’re otherwise generally healthy and could attend our clinic in Newstead, Brisbane, for initial enrolment and then two progress check-ups over a 6 week study period, we’d love your help.

More information is below, and the Eligibility & Registration form is on this page.

About the product you'll help test...a kiwi fruit extract.

The product is a freeze-dried kiwi fruit concentration powder made from New Zealand grown, GMO free, green Kiwis. Kiwi fruit contains a number of different compounds including enzymes, antioxidants and fibre, all of which are believed to be beneficial for relief from gastrointestinal discomfort, including bloating, abdominal pain, constipation and diarrhoea. Kiwi fruit is also a source of the antioxidant Lutein, which has been shown to improve Macular Pigment Optical Density (MPOD), a leading cause of blindness in the western world.
