Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Ubiquinol CoQ10

Participants will be required to take one capsule orally, twice daily with food (one in the morning and one in the evening). Each capsule contains 100mg Ubiquinol, therefore participants will consume 200mg each day for 3 months. Participants will be provided with a 3-month supply of the study product at their baseline visit and will then take the capsules twice daily in their own home.

Participants will be provided with a diary/log that they will be instructed to tick when they have taken their treatment each day. In addition, they will be required to return any left over treatment at their final visit so that compliance can be calculated based on capsule count.

Treatment: Drugs
Comparator / control treatment
Placebo

Soft gelatin capsule containing the same ingredients as the active treatment, minus the Ubiquinol. Participants will be required to consume two capsules daily, with food. The capsules are identical in taste and appearance to the active capsules.

Study design
Purpose of the study
Treatment
Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
Randomisation codes were generated using specialist randomisation computer software by a disinterested third party. An electronic copy of the codes is kept in a password-protected file not accessible by the study team. Hard copies are also kept in a sealed envelope in a locked filing cabinet not accessible by the study team.
Randomisation codes were allocated based on participant number. Participant numbers will be allocated as participants enter the trial, in the order that they entered the trial (i.e. the first participant to sign consent will be allocated participant number 001 etc.). Treatment allocation will be based on participant number, such that the randomisation number is always the same as the participant number. Participant 001 will receive treatments in the order allocated to randomisation number 001 etc. This will reduce the likelihood of errors being made in treatment allocation.
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
The randomised code list was created using the generator at https://www.sealedenvelope.com/simple-randomiser/v1/lists. The two possible treatment conditions (Active and Placebo) were arbitrarily named Treatment A, Treatment B. This was then entered into the Generator with the total number of subjects being 128 and random block sizes of 4, 6 and 8.

Summary
Brief summary
We propose to study the effects of 3 month supplementation of CoQ10 on cognition versus placebo using a randomized controlled trial methodology. Our focus will be on older participants as this may be a sensitive age for cognitive improvement given that normal increasing age is associated with cognitive decline-particularly memory, the levels of CoQ10 decreases with age, there is increased deterioration in the cardiovascular system with age and finally there is increased oxidative stress with age and less anti-oxidant protection with age. All of these indicators suggest that supplementation with CoQ10 could improve cognitive function in the elderly. Apart from our sensitive cognitive battery we will also measure changes in blood levels of CoQ10 and oxidative stress (F2 Isoprostanes and glutathione peroxidase) as well as markers of cardiovascular function (Blood pressure, arterial stiffness and blood flow).
