ReviewHumans
- Design
- Review
- Subjects
- 48 studies, of which 47 were randomised controlled trials
- Dose used in the study
- The included trials used about 150 to 700 mg, once or twice a day
- Duration
- From 3 days to 53 weeks
- What was measured
- What the randomised trial evidence shows for palmitoylethanolamide across patient populations: neuropsychiatric, neurological, bodily pain and function, gut and internal organ, and blood marker outcomes, following PRISMA 2020 methodology.
What the authors reported
Most included trials rated good quality on the Joanna Briggs Institute tool, two rated fair. Palmitoylethanolamide was well tolerated across the trials, with no relevant adverse events.
Limits of this study
A systematic review without a pooled analysis. The authors note that the trials differ in method and in formulation, which makes them hard to compare. The entry was checked against the article page and the Crossref record. Funding and conflicts were not visible on the page checked.
