Consuming soymilk-honey fermented with a specific type of probiotic significantly reduces osteocalcin levels, which may impact bone health in postmenopausal women.
The researchers conducted a 90-day pre-post quasi-experimental study with control design on 54 postmenopausal women who were divided into three groups. The first group consumed regular soymilk, the second group consumed soymilk-honey fermented with a specific sub species of probiotics, and the third group consumed soymilk-honey fermented with a different type of probiotics. Each participant consumed 100 mL of their respective drink per day for 90 days. Measurements of blood serum osteocalcin were taken at the start and end of the study, alongside assessments of each participant's overall health status, including total cholesterol, blood glucose, and uric acid levels.
In terms of results, it was observed that the group consuming the soymilk-honey fermented with the particular probiotic showed a significant decrease in their osteocalcin levels after the 90-day period. This indicates that this specific fermented soymilk-honey beverage might have a positive impact on bone health in postmenopausal women.

Consuming bicarbonate-calcium mineral water, low in sodium, can help manage calcium imbalance and support bone health in perimenopausal women.

Clinical Study Menopause Mineral Water Osteoporosis
The study involved 120 perimenopausal women who consumed 2 liters of a specific bicarbonate-calcium mineral water (Lete) daily for six months. This water was chosen because it is rich in calcium and bicarbonate but low in sodium. The study aimed to determine the impact of this water on bone health and overall metabolism. The participants’ urine and blood serum were analyzed using NMR-based metabolomic procedures. These analyses were conducted to assess the effects of the water not only on calcium metabolism but also on the broader systemic metabolism.
The findings indicated that the Lete water effectively compensated for calcium dysmetabolism and supported bone health and integrity in perimenopausal women. While the study primarily focused on bone metabolism, it also provided insights into the potential system-wide metabolic effects of this specific type of mineral water. This suggests that such water could be a valuable dietary supplement for addressing calcium-related metabolic issues, particularly in perimenopausal women.
Soybean intake can potentially reduce risks of several cancers, type 2 diabetes, osteoporosis, and hot flashes, and it may negatively impact some drug treatments and cause allergies.

This research primarily involves review and analysis of current clinical studies focusing on the benefits and risks of soybean ingredients. The method appears to be a systematic review of various epidemiological studies which were investigating the correlation between soybean consumption and the risk of developing multiple types of cancers including breast, prostate, colorectal, ovarian, and lung cancers. Besides cancer, other common diseases such as type 2 diabetes, osteoporosis, and menopausal symptoms like hot flashes were also investigated. Moreover, any potential adverse effects of soybean, including its possible detrimental impact on certain drug treatments and its allergenicity, were also factors of study in these clinical evidences.
In the discussion of results, the researchers found a significant inverse association between soybean intake and cancer risks, wherein an increase in the consumption of soybean foods was associated with a reduced likelihood of cancer. Besides showing potential anticancer properties, soybean consumption was found inversely correlated with risks of type 2 diabetes. Soy isoflavones, compounds present in soybeans, also showed potential benefits in the management of osteoporosis and hot flashes. On the other hand, the adverse effects of soybean, including interference with certain drug therapies and causing allergies, were also duly noted. Therefore, the research concludes that while soybean promises several significant health benefits, caution should be exercised for individuals under specific drug treatments or with allergies to soy.
A combination of soybean germ extract and a probiotic significantly improved menopause-related conditions and mood in an ovariectomized rat model.

Animal Study Bacillus Menopause Soybean
The study employed an ovariectomized rat model to understand the effects of a combination of soybean germ extract containing 30% isoflavone and a probiotic. The methodology included assessing the effects of this combination on several health markers including body weight, estrogen markers, uterine and bone health, vascular markers, and neurotransmitter levels in these rats.
Once implemented, the combination of soybean germ extract and the probiotic showcased significant improvement in body weight and uterine and bone health of the rats. There were also noticeable effects on the lipid profile, liver function, and vascular markers. Most interestingly, the combination had a positive impact on the levels of serotonin and norepinephrine, indicating potential mood-enhancing effects, which are crucial in managing symptoms post-menopause. This essentially shows the potential of a dietary approach towards menopausal management, especially given the observed benefits without the side effects typically associated with hormone replacement therapy.

Methodology: This review followed the Preferred Reporting Items for Systematic reviews and Meta-Analyses guidelines. It began with a sophisticated multi-database search, featuring resources like Google Scholar, Scopus, and others. This search targeted articles published from 2017 to March 2023 and used specific keywords for accuracy. Forty-three articles were handpicked from this process after excluding reviews, conference reports, duplicates, inaccessible texts, and any non-English publications.
Discussion of Results: A thorough examination of the chosen articles resulted in the conclusion that soy proteins, soy bioactive peptides, and soy isoflavones are typically safe for human consumption. Furthermore, it was found that the consumption of these compounds may have beneficial effects, potentially lowering risk factors for ailments such as osteoporosis, various cancers, hypertension, atherosclerosis, and more.

Animal Study Menopause Ovarian Function Soy Milk
In this study, non-fermented soy beverage (SB) and soy beverage fermented with Bifidobacterium pseudocatenulatum INIA P815 (FSB) were tested on both cyclic and acyclic C57BL/6J aged female mice which mimic premenopause and menopause conditions respectively. Over a period of 36 days, the beverages were given to the mice and the variables measured included body weight, lipid and inflammatory profile and fertility. In addition, hepatic gene expressions were examined and the faecal microbiota composition was assessed to further understand the effects of the two beverages.
In the results, FSB displayed a higher concentration of the aglycones daidzein and genistein as well as increased antioxidant activity due to the fermentation process. The cyclic mice that were given FSB experienced a significant rise in the number of oocytes and zygotes retrieved. It was also noticed that the triglycerides were lower in the groups that were given FSB compared to the SB groups. However, it was found that neither of the treatments significantly influenced the inflammatory profile or caused a major shift in intestinal microbiota or hepatic gene expressions in either of the groups. Still, it was observed that FSB had more health benefits than SB with regards to the lipid profile and fertility in the cyclic mice, likely due to the increased bioavailability and bioactivity of compounds due to fermentation.
