Observational studyHumans

Design
Observational study
Subjects
72 German Emergency Medical Services personnel
Dose used in the study
Not applicable; palmitoylethanolamide was measured in hair, not given
Duration
1 cm hair strands, reflecting roughly the previous month
What was measured
Hair cortisol, anandamide, 2-AG, stearoylethanolamide, oleoylethanolamide and palmitoylethanolamide, correlated with workload, lifetime trauma exposure and mental and physical health symptoms.

What the authors reported

This observational study found:

  • Cortisol and 2-AG were negatively correlated.
  • Higher cortisol went with higher workload.
  • Reported childhood and later traumatic stress and more severe depressive and physical stress symptoms were associated with higher 2-AG, stearoylethanolamide, oleoylethanolamide and palmitoylethanolamide concentrations.

Limits of this study

A cross-sectional correlation study of the body's own PEA; it did not test PEA treatment and cannot show cause. The authors declare no competing interests.
