Controlled trialHumans

Design
Controlled trial
Subjects
17 women with major depressive disorder
Dose used in the study
No palmitoylethanolamide was given; serum levels were measured
Duration
Two separate 20-minute cycling sessions, one at prescribed moderate intensity and one at self-selected intensity
What was measured
Serum anandamide, 2-AG, palmitoylethanolamide, oleoylethanolamide and 2-oleoylglycerol before and within 10 minutes after exercise; mood and state anxiety before and at 10 and 30 minutes after.

What the authors reported

The study found:

  • Moderate exercise raised anandamide (P=0.013) and oleoylethanolamide (P=0.024), with moderate negative correlations between these changes and mood disturbance.
  • No change in palmitoylethanolamide is reported.
  • Self-selected exercise produced no changes in any lipid and no lipid-mood relationships.

Limits of this study

A small within-subjects study; no PEA was given and palmitoylethanolamide showed no reported change. Results are in women with depression only. Funding and conflicts not stated in the abstract.
