简要总结
Perimenopause is a stage of transition into menopause that is marked by menopausal symptoms while menstruation is still taking place. Perimenopause symptoms include mood changes, anxiety, sleep disruptions, hot flushes, night sweats, fatigue, and cognitive challenges. The frequency and severity of these symptoms can seriously impair women's quality of life. Even if the public's awareness on menopause has increased, there are still a lot of unanswered questions. A connection between nutrition and menopause management has been proposed in earlier research. However, there is limited research in this field, and women frequently turn to social media for supplement recommendations in order to deal with menopause-related issues.
Vitamins and minerals such as vitamin D and calcium are recommended by the European Menopause and Andropause Society and there is limited evidence to suggests that soy and herbals may have a beneficial effect on menopausal symptoms, but more research is needed.
The aim of this study is to investigate the effects of 12-weeks multi-vitamin/mineral and herbal extract-containing supplement on menopause symptoms, memory and concentration, sleep, and psychological well-being.
详细描述
Perimenopause is the stage of a woman's life when she has not yet gone a full year without her period but is still undergoing changes due to changing hormones. It often occurs in our 40s, but some women may experience it sooner. It is a normal aspect of aging. While each person experiences symptoms differently, some common ones include irregular periods, hot flushes, night sweats, mood swings, difficulty sleeping, decreased libido, vaginal dryness, memory and concentration problems, joint and muscle aches, fatigue, headaches, and changes in skin or hair.
Hormone replacement therapy (HRT), which is available through general practitioners and comes in a variety of forms, is currently the first line of treatment for menopause symptoms. However, some people might decide against using HRT because of adverse effects or because it's inappropriate for them for other reasons.
Supplement companies are starting to market to women who are increasingly using social media to seek advice on how to manage their symptoms by making claims that their products can lessen menopausal symptoms.
Although there is evidence linking nutrition to menopause, there are limited research on the subject, especially when it comes to perimenopause. The European Menopause and Andropause Society recommends vitamins and minerals including calcium and vitamin D. There is also some evidence that soy and herbal remedies like sage, green tea, and ashwaganda may help with menopausal symptoms, but more research is required.
The aim of this study is to investigate the effects of a multi-vitamin/mineral and herbal extract-containing supplement on menopause symptoms, memory and concentration, sleep, and psychological well-being when taken for 3 months. These effects will be compared to the effects of an inert placebo taken over the same time frame.
