Cinnamon potential in alleviating early postmenopause symptoms: a randomized clinical trial.

Objective: Menopause is a substantial physical, mental, and emotional transition in a woman's life. Most women suffer symptoms during menopause, impacting their quality of life for a decade or more. This study aimed to determine the effect of cinnamon on the severity of postmenopause symptoms.

Methods: A randomized, triple-blind, parallel clinical trial was conducted on 60 postmenopausal women in the health centers of Hamadan, Iran. The study included women aged 45 to 60 years who were 1 to 3 years after their last menstrual period. The participants were assigned to two groups using a permuted block randomization method. The intervention group received a daily dose of one cinnamon capsule (1 g) for 2 months, whereas the control group received a placebo. The participants, researchers, and statistical analysts were all blinded. The study measured the severity of menopause symptoms using the Menopause Rating Scale before and 2 months later. Data were analyzed using Stata-13 software.

Results: Data from 59 individuals were analyzed. The analyses were adjusted for baseline Menopause Rating Scale scores. After the intervention, the severity of menopause symptoms was lower in the intervention group (13.95 ± 4.16) compared to the control group (16.64 ± 4.16) (P = 0.01), with an effect size of 0.65 (95% CI, 0.12-1.17). Additionally, the intervention group had lower scores for psychological symptoms compared to the control group (P = 0.006), with an effect size of 0.74 (95% CI, 0.21-1.27).

Conclusions: The consumption of cinnamon in postmenopausal women has been found to improve the severity of menopause symptoms, with a particular emphasis on the psychological domain.
