Effects of Lactobacillus gasseri CP2305 on Mild Menopausal Symptoms in Middle-Aged Women.

Lactobacillus gasseri CP2305 (CP2305) is a paraprobiotic that exhibits beneficial effects on the intestinal function and microbiota, and increases resistance to psychological stress. The stress response mechanism mainly involves the hypothalamic-pituitary-adrenal axis, which is influenced by the gut-brain axis. Furthermore, the gut-brain axis also communicates bidirectionally with the intestinal microbiota. Additionally, the hypothalamic-pituitary-adrenal and hypothalamic-pituitary-gonadal axes share a common route that affects both mental and health aspects in women. This double-blind, placebo-controlled, parallel-group clinical trial aimed to analyze the influence of the intake of CP2305 on mild symptoms associated with menopause. Eighty women aged 40-60 years ingested CP2305 or placebo tablets for six consecutive menstrual cycles. Assessment was based on the observation of climacteric symptoms with two validated questionnaires-the Simplified Menopausal Index (SMI) and the Greene Climacteric Scale (GCS). The results showed that CP2305 provided significant relief in the SMI total score, SMI vasomotor score, SMI psychological score, GCS total score, GCS somatic score, and GCS vasomotor score compared to the placebo. The percentage of women with symptom relief for the SMI total score was 75.0%, with 30 of 40 women in the CP2305 group, and 55.0%, with 22 of 40 women in the placebo group (p = 0.0594). These findings provide new insights into the function of paraprobiotic CP2305 in relieving mild climacteric symptoms in women.
