Preliminary research suggests that probiotics may help reduce menopausal symptoms. Therefore, the aim of this study is to investigate the effects of a probiotic called LactoSpore® on hot flushes, night sweats and other menopausal-related symptoms (e.g., changes in mood, sleep, energy, libido, cognition, weight, digestion, or joint pain) in perimenopausal women experiencing, on average, at least 3 hot flushes/ night sweats a day. Furthermore, to help understand how LactoSpore® works, changes in blood markers that may influence menopausal symptoms will be examined over time.
If you are a generally healthy female aged 40-55 years, experiencing perimenopause and, on average, having at least 3 hot flushes/night sweats per day, we invite you to participate in this randomised, controlled study.
PLEASE NOTE: Travel to our office in Duncraig is required on TWO occasions
Eligible participants will be RANDOMLY allocated into ONE of TWO treatment conditions:
- Daily intake of capsules containing a probiotic, or
- Daily intake of placebo (fake) capsules
This 12-week study consists of the following:
- Visit our office (located in Duncraig, Western Australia) on 2 occasions (days 0 and week 12). During these in-person visits (approximately 60 minutes), we will measure your weight, height, and blood pressure. You will also need to complete several questionnaires regarding your menopausal symptoms, mood, sleep, and fatigue.
- Visit a Western Diagnostics Pathology clinic to have a blood sample collected from you at the beginning and end of the study.
- Take 1 capsule once daily for 12 weeks.
- Keep a 7-day record of your hot flushes/night sweats at weeks 0 (baseline), 4, 8, and 12. This will be done on your phone and will take less than 1 minute daily.
- Complete online questionnaires in weeks 4 and 8, which will take around 5 to 10 minutes.
