Brief Summary:
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.

Detailed Description:
This randomised, double-blind, placebo-controlled, counterbalanced crossover study will assess the acute effects of chewing functional gum on measures of concentration and mental acuity in healthy participants in comparison to basic sugar free gum and placebo.
The trial will utilise the COMPASS cognitive assessment system and a series of subjective mood measures. The core cognitive assessment of study will employ a selection of tasks assessing performance within the 'Psychomotor Speed', 'Sustained Attention', and 'Decision Making' cognitive domains. Subjective changes in mood ('alertness', 'stress', 'tranquillity', concentration', 'focus' and 'mental tiredness') will also be assessed.
Assessments will take place at baseline, during treatment consumption and 1 hour post-dose to assess the residual effects following chewing.
Participants will have an initial remote screening session followed by visits to the laboratory on 4 separate occasions: an introductory/training visit (Day 0) and three active study days (Day 1, Day 2, and Day 3) spaced 2 days apart (+5 days).
The remote screening session will be completed via telephone call and will comprise: briefing on requirements of the study, obtaining of informed consent via completion of an online consent form, health screening, collection of demographic data, and completion of the Caffeine Consumption Questionnaire (CCQ).
The introductory/training visit to the laboratory will begin with physiological eligibility measures that cannot be completed remotely (e.g. height and weight, waist-to-hip ratio) followed by training on the cognitive and mood measures.
Following the introductory visit participants will attend the laboratory at either 10 am or 2 pm on three separate occasions (Day 1, Day 2, and Day 3) with testing time consistent within participants and counterbalanced across treatment orders. All testing days (will be identical, with the exception that the participants will consume a different treatment at each visit.
On each testing visit participants will be required to eat a standard meal at least 1 hour before testing and to abstain from alcohol and over the counter medications (including hay fever medications) for 24 hours and caffeinated products for 5 hours before testing (meal items should be kept consistent across visits). Participants will arrive to the laboratory at their allotted time and, following completion of the Case Report Form (to confirm continued compliance with inclusion/exclusion criteria), complete a baseline assessment for that day (10 mins). They will then be randomised to treatment order (Day 1 only). Participants will have a 10-minute rest before completing the tasks again whilst 'chewing' their allotted treatment for that day (10 mins). Following this they will dispose of their treatment and then complete a final assessment 1 hour later to assess the residual effects following chewing.
Testing will take place in a suite of testing facilities with participants visually isolated from each other.
