Northumbria University, Newcastle upon Tyne, United Kingdom, is conducting the clinical trial Immediate and Residual Effects of Functional Chewing Gum on Concentration.

Previous research suggests that chewing gum may influence several functions including attention and alertness. Gum can also be used as a vehicle for delivering ingredients that have the ability to modulate attention and mood.

This study will explore the effects of a functional gum containing a proprietary composition of a herbal extract and vitamins. These effects will be compared to the effects of a basic sugar-free gum and to a tablet which will include the same ingredients as the basic sugar-free gum. Effects will be explored on computerised measures of attention/concentration and via ratings of current mood. The study will assess the immediate effects of chewing gum as well as the effects 1 hour later. There will be an initial remote screening session followed by visits to the laboratory on 4 separate occasions: an introductory/training visit and three active study days.

It is planned to include 40 participants. The researchers expect to complete the study by January 4, 2023.

One primary outcome measure is Simple Reaction Time, Cognitive Function - attention.

Participants must self-assess themselves as being in good health and be 18 to 35 years at the time of giving consent, with chewing ability and proficient in English.  They cannot participate if have any pre-existing medical condition/illness which will impact taking part in the study.
