OBJECTIVE: Primary dysmenorrhea is one of the most commonly reported disorders for women that have unfavorable effects on patient's quality of life. Based on the evidences that suggest the anti-inflammatory and analgesic properties of chlorella, this double-blind, randomized, placebo controlled clinical trial aimed to evaluate the effects of Chlorella supplementation on the severity of menstrual pain in a group of young women with primary dysmenorrhea.

STUDY DESIGN: In this clinical trial, 44 girls with primary dysmenorrhea were randomly divided into intervention and control groups. Patients in the intervention group received 1500 mg/day of chlorella as 5 soft gel and the control group received placebo soft gels for eight weeks. Menstrual and food information were collected using a previously validated and published questionnaire. Anthropometric measurements and biochemical parameters including prostaglandin E2 (PGE2), ProstaglandinF2a (PGF2a), high-sensitivity C-reactive protein (hs-CRP) and malondialdehyde (MDA) were assessed at baseline and end of week eight.

RESULTS: In chlorella supplemented group the PGE2, PGF2a, hs-CRP and MDA decreased significantly (P < 0.05). The severity and duration of dysmenorrheal pain were significantly reduced in the intervention group compared to the control group (p < 0.05). Systemic symptoms of dysmenorrhea (fatigue, headache, nausea, vomiting, lack of energy) decreased in the chlorella group (p < 0.05). The mean of menstrual characteristics, anthropometric indices and daily energy and macronutrient intake in both intervention and control groups were not changed significantly.

CONCLUSION: This study showed that chlorella supplementation could decrease the severity of pain and systemic symptoms and improve serum levels of prostaglandins, inflammatory and oxidative markers in women with primary dysmenorrhea.
