Brief summary

This is a double-blind, randomised, clinical trial with a 2-month treatment duration with 2 arms (1 active ingredient arm and 1 placebo arm). Participants will be recruited from databases and public media outlets. Following preliminary screening via telephone, potential participants will attend the clinic for an information session and will be required to provide their consent for inclusion in the trial. Consenting participants will undergo a health assessment including lifestyle, current medications and medical history; this data will be used for the comprehensive screening and to provide contextual data for the study. Once enrolled in the trial, participants will be randomly allocated to either the placebo group or the active intervention groups. Briefly, participants will have baseline measurements performed and receive a 2-month supply of the study product. Baseline testing includes: several questionnaires (Pittsburgh sleep quality survey, Epworth sleepiness scale, PROMIS sleep disturbance, self-assessment of sleep quality, Consensus sleep diary, SF-36, GI tolerance), anthropometry measures (weight, height, BMI, waist/hip circumference), 20 mL blood sample (TNF-a, IL-6, IL-8, IL-10, hs-CRP, PEA concentration, ELF/T) and wrist actigraphy (3 days wearing a Polar A370). Participants will be asked to consume the allocated product according to the dose prescribed (350 mg/day PEA or placebo). An opaque bottle containing opaque vegetable capsules will be provided to each participant according to their group allocation. Participants will then return at timepoint: 8 weeks for subsequent testing. At the 8-week time points, the testing will be a repeat of baseline measurements. At 5 days, 2 and 4 weeks the participants will complete the same testing except for any blood markers and anthropometry measurements. Two weeks after treatment cessation participants will be asked to complete questionnaires again online.

Interventions

Palmitoylethanolamide (PEA) is the intervention. Each dose will contain 350mg (2 x 175 mg) of Levagen CWD PEA. Each 175 mg capsule contains 157.5 mg of PEA and 17.5 mg of excipient (maltodextrin). Each product will be consumed as per the following: Two capsules containing 175mg of PEA and maltodextrin with water one hour prior to sleep onset for 8 weeks duration. PEA is also approved for sale as a food for special medical purposes. Compliance will be monitored via capsule return at the end
