Observational studyHumansWith phycocyanin

This study tested palmitoylethanolamide together with phycocyanin. Its results cannot be assigned to palmitoylethanolamide alone. More combination studies.

Design
Observational study
Subjects
61 women with migraine without aura (from 800 records reviewed, 220 screened)
Dose used in the study
Two capsules daily of phycocyanin and palmitoylethanolamide, from five days before to five days after menstruation onset
Duration
Three consecutive months
What was measured
Migraine severity, frequency and duration during the perimenstrual window; analgesic use; migraine-associated symptoms; compared with a three-month period without supplementation.

What the authors reported

This retrospective observational study found:

  • Migraine severity fell significantly across all perimenstrual days (p<0.0001).
  • Overall monthly attack frequency was unchanged, but perimenstrual migraine days fell from month one (p<0.05).
  • Migraine duration fell at one, two and three months.
  • Analgesic use and migraine-associated symptoms also fell.
  • Treatment was well tolerated.

Limits of this study

A retrospective study with no control group, so it cannot separate the effect of PEA from phycocyanin or from natural fluctuation. Publication costs were supported by Kura Srl; one author was employed by a headache clinic named in the paper.
