Raval SD, Archana G. Evaluation of synbiotic combinations of commercial probiotic strains with different prebiotics in in vitro and ex vivo human gut microcosm model. Arch Microbiol 2024; 206:315. [PMID: 38904672 DOI: 10.1007/s00203-024-04030-3] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/01/2024] [Revised: 05/25/2024] [Accepted: 06/04/2024] [Indexed: 06/22/2024]
Abstract
Exploring probiotics for their crosstalk with the host microbiome through the fermentation of non-digestible dietary fibers (prebiotics) for their potential metabolic end-products, particularly short-chain fatty acids (SCFAs), is important for understanding the endogenous host-gut microbe interaction. This study was aimed at a systematic comparison of commercially available probiotics to understand their synergistic role with specific prebiotics in SCFAs production both in vitro and in the ex vivo gut microcosm model. Probiotic strains isolated from pharmacy products including Lactobacillus sporogenes (strain not labeled), Lactobacillus rhamnosus GG (ATCC53103), Streptococcus faecalis (T-110 JPC), Bacillus mesentericus (TO-AJPC), Bacillus clausii (SIN) and Saccharomyces boulardii (CNCM I-745) were assessed for their probiotic traits including survival, antibiotic susceptibility, and antibacterial activity against pathogenic strains. Our results showed that the microorganisms under study had strain-specific abilities to persist in human gastrointestinal conditions and varied anti-infective efficacy and antibiotic susceptibility. The probiotic strains displayed variation in the utilization of six different prebiotic substrates for their growth under aerobic and anaerobic conditions. Their prebiotic scores (PS) revealed which were the most suitable prebiotic carbohydrates for the growth of each strain and suggested xylooligosaccharide (XOS) was the poorest utilized among all. HPLC analysis revealed a versatile pattern of SCFAs produced as end-products of prebiotic fermentation by the strains which was influenced by growth conditions. Selected synbiotic (prebiotic and probiotic) combinations showing high PS and high total SCFAs production were tested in an ex vivo human gut microcosm model. Interestingly, significantly higher butyrate and propionate production was found only when synbiotics were applied as against when individual probiotic or prebiotics were applied alone. qRT-PCR analysis with specific primers showed that there was a significant increase in the abundance of lactobacilli and bifidobacteria with synbiotic blends compared to pre-, or probiotics alone. In conclusion, this work presents findings to suggest prebiotic combinations with different well-established probiotic strains that may be useful for developing effective synbiotic blends.

Human in vivo assessment of the survival and germination of Heyndrickxia coagulans SNZ1969 spores delivered via gummy candies. Curr Res Food Sci 2024; 9:100793. [PMID: 39071473 PMCID: PMC11278553 DOI: 10.1016/j.crfs.2024.100793] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/18/2024] [Revised: 06/05/2024] [Accepted: 06/15/2024] [Indexed: 07/30/2024] Open
Abstract
Confectionary products hold promise as unconventional food carriers for probiotic microorganisms. This study explored the delivery of Heyndrickxia coagulans SNZ1969, a spore-forming probiotic, using gummy candies. In this study, we prepared gummy candies containing bacterial spores with a viable count that remained stable during a 24-month shelf-life period, meeting the label claim of at least one billion CFUs per serving (24 g). Then, we carried out an intervention trial involving 24 healthy adults who consumed one serving per day for two weeks followed by an additional two weeks of follow-up. Fecal samples were collected and analyzed with a protocol that allowed the viable counts of SNZ1969, both in spore and vegetative forms. The obtained results revealed that bacterial spores germinated in all volunteers. SNZ1969 persistence in the gut was monitored for two weeks after the end of gummy candy consumption, indicating its potential for prolonged colonization. These findings highlight the potential of unconventional food carriers for probiotic delivery and suggest that spore-forming probiotics can be metabolically active in the human intestine. These findings provide information for the development of food products containing spore-forming probiotics and their potential benefits in promoting gastrointestinal health.

Abstract
Bifidobacteria, frequently present in the human gastrointestinal tract, play a crucial role in preserving gut health and are mostly recognized as beneficial probiotic microorganisms. They are associated with fermenting complex carbohydrates, resulting in the production of short-chain fatty acids, bioactive peptides, exopolysaccharides, and vitamins, which provide energy and contribute to gut homeostasis. In light of these findings, research in food processing technologies has harnessed probiotic bacteria such as lactobacilli and bifidobacteria for the formulation of a wide range of fermented dairy products, ensuring their maximum survival and contributing to the development of distinctive quality characteristics and therapeutic benefits. Despite the increased interest in probiotic dairy products, introducing bifidobacteria into the dairy food chain has proved to be complicated. However, survival of Bifidobacterium species is conditioned by strain of bacteria used, metabolic interactions with lactic acid bacteria (LAB), fermentation parameters, and the temperature of storage and preservation of the dairy products. Furthermore, fortification of dairy foods and whey beverages with bifidobacteria have ability to change physicochemical and rheological properties beyond economic value of dairy products. In summary, this review underscores the significance of bifidobacteria as probiotics in diverse fermented dairy foods and accentuates their positive impact on human health. By enhancing our comprehension of the beneficial repercussions associated with the consumption of bifidobacteria-rich products, we aim to encourage individuals to embrace these probiotics as a means of promoting holistic health.

Abstract
Considering the importance of a healthy uterus to the success of breeding, the beneficial effects of lactic acid bacteria on animal reproduction function are of particular interest. In recent decades, infertility has become a widespread issue, with microbiological variables playing a significant role. According to reports, dysbiosis of the vaginal microbiota is connected with infertility; however, the effect of the normal vaginal microbiota on infertility is unknown. In addition, lactic acid bacteria dominate the reproductive system. According to evidence, vaginal lactic acid bacteria play a crucial role in limiting the invasion of pathogenic bacteria by triggering anti-inflammatory chemicals through IL-8, IL-1, and IL-6; immunological responses through inhibition of the adherence of other microorganisms, production of inhibiting substances, and stimulation of mucus production; and also reproductive hormones by increased testosterone hormone release, enhanced the levels of luteinizing hormone, follicle stimulating hormone, the amount of prostaglandin E (2), and prostaglandin F2 alpha. The objective of this study was to compare the advantages of lactic acid bacteria in animal reproduction based on the most recent literature. The administration of a single strain or numerous strains of lactic acid bacteria has a favourable impact on steroidogenesis, gametogenesis, and animal fertility.

Abstract
Probiotics and prebiotics relieve constipation by altering the composition of the intestinal microbiota. However, their synergistic mechanism of action remains unclear. Herein, an in vitro fermentation model was constructed to examine the synergistic effects of Bifidobacterium lactis BL-99 and fructooligosaccharide (FOS) on the regulation of intestinal microbiota from a population with constipation. The utilization of FOS was promoted by BL-99, and the increase rate being 22.33%. Relative to the BL-99 and the FOS groups, the BL-99_FOS group showed a highly significant increase in acetic acid content (P < 0.01) and a marked decrease in CO2 and H2S contents (P < 0.01) in the fermentation broth. In addition, the BL-99_FOS combination significantly changed the structure of the intestinal microbiota, enhanced the relative abundances of beneficial bacteria that relieved constipation, including Bifidobacterium, Fecalibacterium, Lactobacillus, Subdoligranulum, and Blautia, and decreased those of the harmful bacteria, including Bilophila and Escherichia-Shigella. These findings suggested that BL-99 and FOS synergistically regulated the composition and structure of the intestinal microbiota from the population with constipation and increased acetic acid and decreased CO2 and H2S levels, thereby providing a theoretical basis for the application of synbiotics.

Colonization Ability and Impact on Human Gut Microbiota of Foodborne Microbes From Traditional or Probiotic-Added Fermented Foods: A Systematic Review. Front Nutr 2021; 8:689084.

Abstract
A large subset of fermented foods act as vehicles of live environmental microbes, which often contribute food quality assets to the overall diet, such as health-associated microbial metabolites. Foodborne microorganisms also carry the potential to interact with the human gut microbiome via the food chain. However, scientific results describing the microbial flow connecting such different microbiomes as well as their impact on human health, are still fragmented. The aim of this systematic review is to provide a knowledge-base about the scientific literature addressing the connection between foodborne and gut microbiomes, as well as to identify gaps where more research is needed to clarify and map gut microorganisms originating from fermented foods, either traditional or added with probiotics, their possible impact on human gut microbiota composition and to which extent foodborne microbes might be able to colonize the gut environment. An additional aim was also to highlight experimental approaches and study designs which could be better standardized to improve comparative analysis of published datasets. Overall, the results presented in this systematic review suggest that a complex interplay between food and gut microbiota is indeed occurring, although the possible mechanisms for this interaction, as well as how it can impact human health, still remain a puzzling picture. Further research employing standardized and trans-disciplinary approaches aimed at understanding how fermented foods can be tailored to positively influence human gut microbiota and, in turn, host health, are therefore of pivotal importance.

Abstract
Synbiotic yogurts (SYs) are potential natural cures with improved health outcomes and prevention and control of chronic diseases through the synergistic action of probiotic bacteria and prebiotic compounds. Recent clinical achievements in consuming SYs in healthy and patient pediatric and adult populations were critically reviewed. Some forthcoming challenges and interesting solutions to increase healthy nutritional effects of these dairy products have also been addressed. The use of SY-based nutrition pattern in children can considerably increase their body's immunity with an improvement in social and school functioning. SY consumption not only reduces childhood digestive problems but also remarkably decreases the illness duration and symptoms' severity. Increasing the number of bifidobacteria and lactobacilli in gastrointestinal (GI) tract of healthy adults consuming SYs can significantly reduce the pathogenic bacteria in feces. The regular intake of SYs with enhanced bioavailability of bioactive compounds in a short intestinal transit time reduces the risk of cardiovascular disease among hypercholesterolemic adults. Also, a meaningful improvement in the health status of adult patients with irritable bowel syndrome and nonalcoholic fatty liver disease has been assessed after eating this bio-functional supplement product. Administration of a healthy SY-based diet purposefully alters microbiota composition, provides a microbial balance in the gut, and promotes GI functions in pediatric and geriatric age groups. Full recovery without any further complications during the follow-up period in elderly patients can also be obtained by implementing the SY-based dietary guideline.

Abstract
Elderly people are an important part of the global population who suffer from the natural processes of senescence, which lead to changes in the gut microbiota composition. These modifications have a great impact on their quality of life, bringing a general putrefactive and inflammatory status as a consequence. Some of the most frequent conditions related to this status are constipation, undernutrition, neurodegenerative diseases, susceptibility to opportunistic pathogens, and metabolic disbalance, among others. For these reasons, there is an increasing interest in improving their quality of life by non-invasive treatments such as the consumption of probiotics, prebiotics, and synbiotics. The aim of the present mini-review is to describe the benefits of these functional supplements/food according to the most recent clinical and pre-clinical studies published during the last decade. In addition, insights into several aspects we consider relevant to improve the quality of future studies are provided.

Abstract
The screening of novel probiotic strains from various food sources including fruits, vegetables, herbs, and traditional fermented foods, have been of growing concern recently. Most of these potential probiotic lactic acid bacteria isolates were distinguished from the commercial probiotics based on multiple therapeutic effects and functionalities. Recent in vitro and in vivo investigates have also verified the usage of probiotics to lower the risk of diseases. Application of these novel strains in fermented dairy products is also an emerging trend to improve the physical and quality characteristics, functional properties, and safety of dairy products. Moreover, since dairy products are one of the highest consumed products in the globe, the dispatch channels for fermented dairy products are already established. Therefore, incorporating novel probiotic strains into fermented dairy products might be the most feasible approach for their delivery. In this context, our aim is to discuss the feasibility of dairy products as delivery vehicles for novel probiotic strains. Thus, we summarize the scientific evidence that points to a dynamic future for the production of fermented dairy-based probiotics.

Abstract
BACKGROUND Aging is a complex process marked by alterations on gut functioning and physiology, accompanied by an increase on the inflammatory status, leading to a scenario called "inflammaging". OBJECTIVE To evaluate the effects of a synbiotic substance on systemic inflammation, gut functioning of community-dwelling elders. METHODS This is a secondary analysis from a randomized clinical trial, lasting 24 weeks, including 49 elders, distributed into two groups: SYN (n=25), which received a synbiotic substance (Frutooligossacaride 6g, Lactobacillus paracasei LPC-31 109 to 108 UFC, Lactobacillus rhamnosus HN001 109 to 108 UFC, Lactobacillus acidophilus NCFM 109 to 108 UFC e Bifidobacterium lactis HN019 109 to 108 UFC), or PLA (n=24), receiving placebo. The evaluations consisted of serum IL-10 e TNF-α (after overnight fasting), evaluation of chronic constipation (by Rome III Criteria) and faeces types (by Bristol Stool Form Scale). Data were compared before and after the supplementation time, and between groups. RESULTS No significant differences were found between baseline and final values of serum inflammatory markers. Some subtle beneficial changes were observed in SYN, concerning both gut functioning and faeces types. CONCLUSION From our data, synbiotic supplementation showed a subtle benefit in gut functioning in apparently healthy community-dwelling elders. Our findings can suggest that the benefits in healthy individuals were less expressive than the ones presented in studies with individuals previously diagnosed as dysbiosis. Future studies, comparing elders with and without gut dysbiosis can confirm our findings.

Abstract
Lactobacillus rhamnosus GG (LGG) was the first strain belonging to the genus Lactobacillus to be patented in 1989 thanks to its ability to survive and to proliferate at gastric acid pH and in medium containing bile, and to adhere to enterocytes. Furthermore LGG is able to produces both a biofilm that can mechanically protect the mucosa, and different soluble factors beneficial to the gut by enhancing intestinal crypt survival, diminishing apoptosis of the intestinal epithelium, and preserving cytoskeletal integrity. Moreover LGG thanks to its lectin-like protein 1 and 2 inhibits some pathogens such as Salmonella species. Finally LGG is able to promote type 1 immune-responsiveness by reducing the expression of several activation and inflammation markers on monocytes and by increasing the production of interleukin-10, interleukin-12 and tumor necrosis factor-α in macrophages. A large number of research data on Lactobacillus GG is the basis for the use of this probiotic for human health. In this review we have considered predominantly randomized controlled trials, meta-analysis, Cochrane Review, guide lines of Scientific Societies and anyway studies whose results were evaluated by means of relative risk, odds ratio, weighted mean difference 95% confidence interval. The effectiveness of LGG in gastrointestinal infections and diarrhea, antibiotic and Clostridium difficile associated diarrhea, irritable bowel syndrome, inflammatory bowel disease, respiratory tract infections, allergy, cardiovascular diseases, nonalcoholic fatty liver disease, nonalcoholic steatohepatitis, cystic fibrosis, cancer, elderly end sport were analyzed.

Abstract
Studies devoted to evaluating the outcome of different doses of probiotics are very limited, especially for multistrain formulations. In this context, we performed an intervention study that aimed to compare the effect of the administration of two doses (7 billion and 70 billion bacterial cells) of a multistrain probiotic formulation on the persistence of the four probiotic strains that were present in the product in the fecal samples collected from healthy subjects. The overall persistence of the probiotic strains was significantly higher for the 70 billion formulation than for the 7 billion formulation. Furthermore, probiotic strains were detected earlier and for longer for the 70 billion formulation compared to those for the 7 billion formulation. All probiotic strains were recovered alive from the 70 billion preparation, whereas recovery was not possible in a few fecal samples upon administration of the 7 billion preparation. In addition, the overall number of viable probiotic cells recovered on day 14 (i.e., the last day of consumption) was significantly higher for the 70 billion formulation than that for the 7 billion formulation. Finally, we found that the viability of the probiotic cells was stable over the course of the trial independent of volunteers' handling, demonstrating good manufacturing of the product. In conclusion, this study demonstrated that strains belonging to different taxa may coexist in the human gastrointestinal tract upon ingestion of a multispecies probiotic formulation. Moreover, this study suggests that higher doses of bacterial cells in probiotic formulations may permit a higher, earlier, and longer recovery of the probiotics in the feces of healthy adults.

Abstract
Probiotics are live microorganisms, and viability after transit through the gastrointestinal tract (GIT) is considered an inherent property of the health benefits of probiotics. The aim of the present study was to quantify the viable and total loads of Lactobacillus paracasei DG cells after passage through the GIT following the consumption of the probiotic product Enterolactis (L. casei DG®; L. paracasei CNCM I-1572; L. paracasei DG) from drinkable vials by healthy adults. We developed a novel method for discriminating and enumerating culturable L. paracasei DG cells based on the unique sticky, filamentous phenotype of this strain on MRS agar containing vancomycin and kanamycin. The identity of DG was also confirmed with strain-specific primers by colony PCR. This method was used for a recovery study of the DG strain to quantify viable cells in the fecal samples of 20 volunteers during a 1-week probiotic consumption period and a 1-week follow-up. We isolated L. paracasei DG from at least one fecal sample from all the volunteers. The highest concentration of viable DG cells [ranging from 3.6 to 6.7 log10 colony-forming unit (CFU) per gram of feces] in the feces was observed between 4 and 8 days from the beginning of Enterolactis intake and for up to 5 days after cessation of intake. As expected, the total DG count determined by real-time quantitative PCR (qPCR) was mostly higher than the viable DG cells recovered. Viable count experiments, carried out by combining ad hoc culture-based discriminative conditions and strain-specific molecular biological protocols, unambiguously demonstrated that L. paracasei DG can survive gastrointestinal transit in healthy adults when ingested as Enterolactis in drinkable vials containing no less than one billion CFU at the end of shelf life.

Abstract
Chronic functional constipation is a kind of common intestinal disease that occurs in children, adults and elderly people. This disease not only causes great influence to physiological function, but also results in varying degrees of psychological barriers. At present, constipation treatments continue to rely on traditional methods such as purgative therapy and surgery. However, these approaches can disrupt intestinal function. Recent research between intestinal diseases and gut microbiota has gradually revealed a connection between constipation and intestinal flora disturbance, providing a theoretical basis for microbial treatment in chronic constipation. Microbial treatment mainly includes probiotic preparations such as probiotics, prebiotics, synbiotics and fecal microbiota transplantation (FMT). Due to its safety, convenience and curative effect, probiotic preparations have been widely accepted, especially gradually developed FMT with higher curative effects. Microbial treatment improves clinical symptoms, promotes the recovery of intestinal flora, and has no complications during the treatment process. Compared with traditional treatments, microbial treatment in chronic constipation has advantages, and is worthy of further promotion from clinical research to clinical application.

Abstract
The gut microbiota is a complex community of bacteria residing in the intestine. Animal models have demonstrated that several factors contribute to and can significantly alter the composition of the gut microbiota, including genetics; the mode of delivery at birth; the method of infant feeding; the use of medications, especially antibiotics; and the diet. There may exist a gut microbiota signature that promotes intestinal inflammation and subsequent systemic low-grade inflammation, which in turn promotes the development of type 2 diabetes. There are preliminary studies that suggest that the consumption of probiotic bacteria such as those found in yogurt and other fermented milk products can beneficially alter the composition of the gut microbiome, which in turn changes the host metabolism. Obesity, insulin resistance, fatty liver disease, and low-grade peripheral inflammation are more prevalent in patients with low α diversity in the gut microbiome than they are in patients with high α diversity. Fermented milk products, such as yogurt, deliver a large number of lactic acid bacteria to the gastrointestinal tract. They may modify the intestinal environment, including inhibiting lipopolysaccharide production and increasing the tight junctions of gut epithelia cells.

Abstract
AIM To develop a novel validated method for the isolation of Bifidobacterium animalis ssp. lactis BB-12 (BB-12) from faecal specimens and apply it to studies of BB-12 and Lactobacillus rhamnosus GG (LGG) recovered from the healthy human gastrointestinal (GI) tract. METHODS AND RESULTS A novel method for isolating and enumerating BB-12 was developed based on its morphologic features of growth on tetracycline-containing agar. The method identified BB-12 correctly from spiked stool close to 100% of the time as validated by PCR confirmation of identity, and resulted in 97-104% recovery of BB-12. The method was then applied in a study of the recovery of BB-12 and LGG from the GI tract of healthy humans consuming ProNutrients® Probiotic powder sachet containing BB-12 and LGG. Viable BB-12 and LGG were recovered from stool after 21 days of probiotic ingestion compared to baseline. In contrast, no organisms were recovered 21 days after baseline in the nonsupplemented control group. CONCLUSIONS We demonstrated recovery of viable BB-12, using a validated novel method specific for the isolation of BB-12, and LGG from the GI tract of healthy humans who consumed the probiotic supplement. SIGNIFICANCE AND IMPACT OF THE STUDY This method will enable more detailed and specific studies of BB-12 in probiotic supplements, including when in combination with LGG.

Abstract
Ageing and physiological functions of the human body are inversely proportional to each other. The gut microbiota and host immune system co-evolve from infants to the elderly. Ageing is accompanied by a decline in gut microbial diversity, immunity and metabolism, which increases susceptibility to infections. Any compositional change in the gut is directly linked to gastrointestinal disorders, obesity and metabolic diseases. Increase in opportunistic pathogen invasion in the gut like Clostridium difficile leading to C. difficile infection is more common in the elderly population. Frequent hospitalisation and high prevalence of nosocomial infections with the ageing is also well documented. Long-term utilisation of broad-spectrum antibiotic therapy is being followed in order to control these infections. Nosocomial infections and antibiotic therapy in combination or alone is leading to gastroenteritis followed by Clostridium associated diarrhoea or antibiotic associated diarrhoea. Above all, use of broad-spectrum antibiotics is highly debated all over the world due to growing antimicrobial resistance. The use of narrow spectrum antibiotics could be helpful to some extent. Dietary supplementation of probiotics with prebiotics (synbiotics) or without prebiotics has improved gut commensal diversity and regulated the immune system. The recent emergence of faecal microbiota transplantation has played an important role in treating recurrent Clostridium associated diarrhoea. This review focuses on various therapeutic interventions for gut dysbiosis and gastrointestinal diseases in the elderly. The possible mechanism for antimicrobial resistance and mechanism of action of probiotics are also discussed in detail.

Abstract
Today, advances in the public health system of most countries have managed to extend notably life expectancy, however, elderly's health remain as a very serious concern. The lifelong stimulation of innate and adaptive immune systems leads to immunosenescence and, as result, to a low ability to produce immunoglobulins against pathogens but also to a low-grade chronic inflammatory state (inflammaging) that is linked to most age-related health problems, such as dementia, Alzheimer or atherosclerosis. This inflammatory state could make the host more sensitive to intestinal microbes, or vice versa, as changes in the gut microbiota composition are related to the progression of diseases and frailty in the elderly population. It was considered that gut microbiota changed during aging, with an increase of Bacteroidetes vs. Firmicutes proportion and a reduction of bifidobacterial counts, however recent studies reported a great inter-individual variation among elderly and a significant relationship between gut microbiota, diet and institution or community living. Intervention studies of probiotics and prebiotics in elderly are not very abundant, but most cases showed that Bifidobacterium populations can efficiently be stimulated with a concomitant decrease of Enterobacteria. Furthermore, also some studies demonstrated that probiotics decreased the synthesis of pro-inflammatory cytokines which are upregulated in the elderly, such as interleukin (IL)-8, IL-6 or tumour necrosis factor ?, among others, and they increased the levels of activated lymphocytes, natural killer cells, phagocytic activity and even showed a greater response to influenza vaccination. This suggests that direct manipulation of the gut microbiota may improve adaptive immune response and reduce inflammatory secretions, therefore compensating immunosenescence effects, however, there are no records of their effect on clinical symptoms or risk for disease. Those facts reveal that this is an open research field with very good scientific perspectives and above all they could bring likely improvements in the wellbeing of our seniors.

Abstract
The purpose of this study was to investigate the effect of synbiotic fermented milk, containing Lactobacillus paracasei and inulin, on oral bioavailability and pharmacokinetics of isoflavones in healthy postmenopausal women. The study was a one-group pre-post treatment study. Twelve subjects were assigned to consume a single oral dose of 375 mL of soy beverage. Blood samples were collected immediately before and at various time points until 32 hours after the administration of the soy beverage. After a washout period, subjects were requested to consume 180 mL of synbiotic fermented milk after breakfast and dinner for 14 days, followed by a single oral dose of 375 mL of soy beverage on the next day. Collection of blood samples after the administration of the soy beverage were performed at the same time points as the former phase. Plasma isoflavone concentrations were measured by using high-performance liquid chromatography (HPLC) technique. In conclusion, this study highlighted that continuous consumption of synbiotic fermented milk followed by a single oral administration of soy beverage significantly enhanced oral bioavailability of isoflavones compared with a single oral dose of soy beverage alone.
