Oleoylethanolamide supplementation decreases dysmenorrhea pain in women

This randomized, double-blind, placebo-controlled study evaluated the effect of 125 mg/day oleoylethanolamide (OEA) supplementation for 2 months on dysmenorrhea symptoms.  The study included 44 female students with dysmenorrhea-related pain, 22 in the OEA group and 22 in the placebo group.

The results showed an increase in total antioxidant capacity (TAC) (p = 0.022), a decrease in menstrual pain (p = 0.040), malondialdehyde (MDA) (p = 0.011), C-reactive protein (CRP) (p = 0.01), and tumor necrosis factor (TNF- α) (p = 0.038) in the OEA group compared to the placebo group. In addition, intragroup changes were statistically significant on mean pain (p = 0.042), TAC (p = 0.032), MDA (p = 0.023), CRP (p = 0.027), and TNF-α (p = 0.029) at end of study in the intervention group.

Thus, these results suggest that oleoylethanolamide can be considered as an alternative medicine to reduce the use of anti-inflammatory drugs to relieve pain related to dysmenorrhea.
