Outcome Measures

Primary Outcomes (1)

  • Cognitive function (lab-based)

    This outcome will be assessed via changes on the cognitive task outcomes (measured via COMPASS). COMPASS is a proprietorial software platform for delivering a range of cognitive tasks; assessing domains like memory and attention, with tasks scored for accuracy (% correct) and speed (msec).

Secondary Outcomes (7)

  • Cognitive function (remote)

  • Mood (Anxiety)

Eligibility Criteria

Age55 Years - 75 Years
Sexall
Healthy VolunteersYes
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • years at time of enrolment
  • Answers yes to the question 'would you say that your memory now is worse now than it used to be in your 20's?'

You may not qualify if:

  • Pre-existing medical condition/illnesses which would impact taking part in the study The explicit exceptions to this were controlled (medicated) arthritis, asthma, hay fever, high cholesterol and reflux-related conditions. Other, unforeseen, exceptions were considered on a case-by-case basis; i.e. participants may have progressed to screening if they had a condition/illness which would not interact with the active treatments or impede performance.
  • Currently taking prescription medications The explicit exceptions to this were contraceptive and hormone replacement treatments for female participants where symptoms were stable and treatment would not change during the course of the study, those medications used in the treatment of arthritis, high cholesterol and reflux-related conditions and those taken 'as needed' in the treatment of asthma and hay fever. As above, there may have been other instances of permitted medication use where no interaction with the active treatments was anticipated.
  • High blood pressure (BP; systolic over 159 mm Hg or diastolic over 99 mm Hg)
  • Body Mass Index (BMI) outside of the range 18.5-30 kg/m2
  • Pregnant, seeking to become pregnant or lactating
  • Learning and/or behavioural difficulties such as dyslexia or Attention Deficit Hyperactivity Disorder (ADHD)
  • Visual impairments not corrected with glasses or contact lenses (including colour-blindness)
  • Smoking (including vaping)
  • Excessive caffeine intake (\>500 mg per day)
  • Clinically diagnosed food intolerances/sensitivities
  • Antibiotic, prebiotic or probiotic (including drinks; e.g. Yakult or Actimel) use within the past 8 weeks
  • Health conditions preventing fulfilment of the study requirements (this included non-diagnosed conditions for which no medication was taken)
  • Inability to complete all of the study assessments
  • Currently participating in other clinical or nutrition intervention studies, or had in the past 4 weeks (8 weeks if a probiotic study)
  • Diagnosed with/ undergoing treatment for alcohol or drug abuse in the last 12 months
  • +6 more criteria

Masking Details
Double blind with a placebo control. The study funder organised the formulation of both the active and placebo capsules originally in 2019 so that they were aesthetically identical. Approximately half-way through the trial, the treatments expired due to Covid-19-induced delays and the remainder of the products required to complete the trial were reconstituted by staff at Northumbria University who had no further involvement in the trial. Capsules were again matched to be aesthetically identical between active and placebo but these treatments looked different to those in the first portion of the trial.
