Supplementation with PEA May Help You Fall Asleep Faster
Palmitoylethanolamide (PEA) is a fatty acid amide made from fat. It is found naturally in foods such as egg yolks and peanuts, and in the human body. A new study has found that supplementation with PEA may help people fall asleep faster and feel alert faster when they wake up.
Participants included 103 adults with a disturbed sleeping pattern. They received 305 mg of PEA or a placebo daily for 8 weeks. A wrist actigraphy, sleep diary, and questionnaires were used for 3 consecutive days/nights at baseline, day 5, week 2, week 4, and week 8 to measure sleep quality and quantity. The researchers also evaluated time to feel completely awake and cognition on wakening at baseline and at the end of the study period.
Participants in the PEA group saw a reduction of 19 minutes in time to fall asleep. This means they were falling asleep three times faster than participants in the placebo group. In addition, participants in the PEA group saw significant improvements in how long it took them to feel fully awake, going from 26 minutes at baseline to 15 minutes at the end of the study period.
The study was conducted by researchers from the University of Sydney. It was published online ahead of print on September 10, 2021 in the journal Sleep Science and Practice.
