Study type
Interventional
Description of intervention(s) / exposure
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 of the study.

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)
The potential participants are screened by the investigator for inclusion in the study. The eligible participants are enrolled by investigator and provided with a "Numbered Container" that is identical to all other containers and contains the same information on the label, except for the number. The investigator is blinded to the product randomized with the
numbered containers labelled prior to delivery to investigational site. Product allocated as participants are enrolled in sequential order

Methods used to generate the sequence in which subjects will be randomised (sequence generation)
