Probiotics / 12.12.2024

Editor's note: Please remember probiotic supplements are not FDA tested or approved. Some may have side effects especially in persons prone to certain health care conditions.  Potential benefits of probiotics have also not been generally confirmed in well controlled clinical trials.  Please discuss your potential use of probiotics and any supplements with your health care providers. Probiotics play a crucial role in maintaining a healthy gut. These beneficial bacteria are known for their ability to support digestion, promote gut health, and boost the immune system, which is why probiotic supplements are so popular among health enthusiasts.  Among the vast array of probiotic strains, Lactobacillus rhamnosus is a prominent player in gut health and overall well-being. This guide explores the specifics of Lactobacillus rhamnosus, exploring its characteristics, benefits, and why it's gaining recognition in the realm of probiotics.

What Are Probiotics?

Probiotics are live microorganisms that offer many health benefits to the host when consumed in adequate amounts. They work by restoring the balance of good bacteria in the digestive system, aiding digestion, and supporting immune function.  These friendly bacteria can be found in various foods and supplements like URO Probiotics, offering a natural way to improve gut health and overall wellness. With an increasing focus on the gut-brain connection and the importance of a healthy gut microbiome, probiotics have garnered significant attention in the field of health and nutrition. (more…)

Editor's note:  Please consult with your health care provider before using any supplements including probiotics. Side effects are uncommon but may occur. The connection between the gut and the brain is one of the most fascinating areas of research in recent years, with scientists uncovering how the microbiome—the trillions of microorganisms residing in our digestive system—can affect not just our digestion and immune system but also our feelings of hunger and satiety. As the science behind the gut-brain axis continues to unfold, it’s becoming increasingly clear that the health of our gut microbiome plays a pivotal role in regulating appetite, food intake, and body weight. Understanding the intricate relationship between gut health and appetite regulation has profound implications for combating obesity, overeating, and eating-related disorders. In this article, we’ll explore how the microbiome influences hunger, the role it plays in appetite regulation, and what you can do to optimize gut health for better control over your hunger and eating habits. We will also look at products which aim to support a healthy microbiome and improve overall well-being.

The Gut-Brain Axis: A Two-Way Communication

The gut-brain axis refers to the bidirectional communication between the gastrointestinal system (gut) and the brain. This connection is facilitated by the vagus nerve, immune pathways, and hormones, which allow the gut and brain to send signals back and forth. Recent research has shown that gut bacteria play a significant role in this communication, influencing not only digestion but also emotions, mental health, and, importantly, appetite regulation. The microbiome, composed of bacteria, viruses, fungi, and other microorganisms, affects the brain’s perception of hunger and fullness through the production of various chemicals, including neurotransmitters, hormones, and metabolites. These signals impact brain regions that control appetite, cravings, and food intake. (more…)

Earlier most probiotic research focused on their role in digestive health and immunity but newer research indicates that probiotics can have additional benefits, especially for women. Some probiotics can help restore and maintain vaginal microflora which would reduce the risk of vaginal infections while others may help to reduce menopause symptoms. Preliminary research also shows that specific probiotic strains can lower stress levels, aid weight loss for those who are overweight, and decrease wrinkles.
  1. Yogurt
Yogurt is one of the most well-known probiotic-rich foods. Not all yogurt contains live probiotics because sometimes processing can kill them which is why you should look for varieties labeled with "live and active cultures". Lactobacillus and Bifidobacterium are the most common probiotics in yogurt so if, for some reason, you are unable to include yogurt in your daily diet, you can take a probiotic capsule that contains these bacteria. You can also compare probiotic supplements for women to see which one is best suited to your needs. (more…)

MedicalResearch.com Interview with: Benjamin Mullish PhD NIHR Academic Clinical Lecturer Department of Metabolism Digestion and Reproduction Imperial College MedicalResearch.com: What is the background for this study? Which probiotic did you use and why?  Response: We recently reported the results of a randomized, double-blind placebo-controlled trial in which participants who were overweight or with obesity (aged between 30-65 years of age) were randomized to receive probiotics or placebo for six months.  The primary focus was on weight loss and metabolism.  The probiotic used was Lab4P, containing three different strains of Bifidobacteria and two of Lactobacilli, which have shown to be safe and efficacious for use in rodent models and earlier clinical studies. Of note, probiotics have also been shown to have other beneficial effects upon human health.  Previous studies have suggested that they may have a role in preventing upper respiratory tract infections (URTIs) in healthy people and children; however, this has not been explored in older people or overweight/ people with obesity, even though such groups have higher rates of URTIs. We looked back at our trial, and reviewed symptom diaries completed by participants daily during the study.  We were looking at recorded symptoms most consistent with upper respiratory tract symptoms (including cough, wheezing and headache), and explored if rates of these were different between those participants taking probiotics compared to placebo over the six month course of the study.   (more…)

MedicalResearch.com Interview with: Professor Mahmoud A. Ghannoum, PhD Director of the Center for Medical Mycology Case Western Reserve School of Medicine and UH MedicalResearch.com: What are the main findings?  Response: The driving force for this study was our finding that patients with Crohn’s disease had a significantly high level (or abundance) of pathogenic fungi (called Candida tropicalis) as well as bacteria (Escherichia coli, and Serratia Marcescens) compared to their non-diseased first-degree relatives. Not only were their levels high, but these organisms cooperated to form polymicrobial digestive plaque (or digestive biofilms) that aggravated the inflammatory symptoms in these patients. Based on this we wanted to develop a probiotic that targeted these organisms and the biofilms they form. Our efforts led to the design of the novel Biohm probiotic which we tested and the results were described in our publication. (more…)

MedicalResearch.com Interview with: Stephen Freedman MDCM, MSc Alberta Children's Hospital Foundation Professor in Child Health and Wellness Sections of Pediatric Emergency Medicine and Gastroenterology Alberta Children's Hospital & Research Institute University of Calgary Calgary, AB  MedicalResearch.com: What is the background for this study? Response: Vomiting and diarrhea remain extremely common diseases in children and are the most common reason children are brought for emergency department care in North America.  While we have options to reduce vomiting there historically has been little physicians can offer to reduce the severity of the diarrhea. Probiotics have recently emerged as an option with some early evidence of benefit in clinical trials but the studies performed to date have been small and few little research has been conducted in North America in outpatient or emergency department children. The one study to date that was performed in a US emergency department did not find probiotic use to be beneficial.  Given the increasing importance of clarifying this issue we undertook this study.

MedicalResearch.com Interview with: "staph aureus on blood agar" by Iqbal Osman is licensed under CC BY 2.0Pipat Piewngam Postdoctorol fellow Pathogen Molecular Genetics Section, Laboratory of Bacteriology, NIAID/NIH Bethesda, MD, USA 20892  MedicalResearch.com: What is the background for this study? What are the main findings?  Response: Our team at National Institutes of health, Mahidol University and Rajamangala University of Technology in Thailand has reported that the consumption of probiotic Bacillus bacteria comprehensively abolishes colonization with the dangerous pathogen, Staphylococcus aureus. We hypothesized that the composition of the human gut microbiota affects intestinal colonization with S. aureus. We collected fecal samples from 200 healthy individuals from rural populations in Thailand and analyzed the composition of the gut microbiome by 16S rRNA sequencing. Surprisingly, we did not detect significant differences in the composition of the microbiome between S. aureus carriers and non-carriers. We then sampled the same 200 people for S. aureus in the gut (25 positive) and nose (26 positive). Strikingly, we found no S. aureus in any of the samples where Bacillus were present. In mouse studies, we discovered S. aureus Agr quorum-sensing signaling system that must function for the bacteria to grow in the gut. Intriguingly, all of the more than 100 Bacillus isolates we had recovered from the human feces efficiently inhibited that system. Then, we discovered that the fengycin class of Bacillus lipopeptides achieves colonization resistance by inhibiting that system. To further validate their findings, we colonized the gut of mice with S. aureus and fed them B. subtilis spores to mimic probiotic intake. Probiotic Bacillus given every two days eliminated S. aureus in the guts of the mice. The same test using Bacillus where fengycin production had been removed had no effect, and S. aureus grew as expected. This is one of the first study that provide human evidence supporting the biological significance of probiotic bacterial interference and show that such interference can be achieved by blocking a pathogen’s signaling system.

MedicalResearch.com Interview with: Hariom Yadav, PhD Assistant Professor, Molecular Medicine Comprehensive Cancer Center Center on Diabetes, Obesity, and Metabolism Redox Biology & Medicine Ctr Sticht Center on Aging MedicalResearch.com: What is the background for this study? What are the main findings? Response: Currently, the use of probiotics is increasing for health benefits of consumers, however the source of probiotics available in the market remains scarcely known. According to scientific community and regulatory standpoint, human-origin probiotics are highly recommended. Hence, we isolated these probiotics from baby diapers, because infant microbiome carries large number of beneficial bacteria. In addition, we optimized our probiotics to produce higher amount of short-chain fatty acids (SCFAs; beneficial metabolites produced by the gut microbiome), because the levels of SCFAs decreases in several human diseases like obesity, diabetes, cancer, autoimmune and inflammatory bowel diseases. Hence, our probiotics can be used to bring back SCFAs levels and may benefit people suffering from these diseases. (more…)

MedicalResearch.com Interview with: Daniel Reis MA Graduate Student Clinical Psychology University of Kansas MedicalResearch.com: What is the background for this study? What are the main findings? Probiotics have generated considerable interest as a possible treatment for numerous forms of physical and mental illness. Preliminary evidence from both preclinical and clinical studies suggest that probiotics may be able to reduce anxiety. Our goal was to comprehensively review and summarize existing preclinical and clinical studies. Overall, probiotic administration reduced anxiety-like behaviors in rodents, but only in those with some form of experimentally-induced disease (such as early-life stress or socieal defeat). Probiotics did not reduce anxiety in humans. (more…)

MedicalResearch.com Interview with: Dr Robert Boyle, Reader in Paediatric Allergy Department of Medicine Imperial College London MedicalResearch.com: What is the background for this study? Response: Diet in early life may influence whether or not an infant develops allergies or autoimmune disease. We undertook a project for the UK Food Standards Agency to evaluate the evidence for this. MedicalResearch.com: What are the main findings?  Response: We found that a probiotic supplement during the last 2-4 weeks of pregnancy and during breastfeeding may reduce an infant’s chances of developing eczema; and that omega-3 fatty acid supplements taken from the middle of pregnancy (20 weeks gestation) through the first few months of breastfeeding may reduce an infant’s chances of developing food allergy. We also found links between longer duration of breastfeeding and improved infant health, but for most other variations in diet during pregnancy or infancy we did not find evidence for a link with allergies or autoimmune disease.

MedicalResearch.com Interview with: “Wine” by Uncalno Tekno is licensed under CC BY 2.0M.Victoria Moreno-Arribas Spanish National Research Council | CSIC  MedicalResearch.com: What is the background for this study? What are the main findings? Response: Recent discoveries indicate polyphenols might also promote health by actively interacting with bacteria in the gut. Also, the intake of specific polyphenol-rich beverages and foods helps the maintenance of digestive health and prevention of disease status. However, the knowledge of the effects of polyphenols in relation to the prevention of dental diseases is still at an early stage. The use of antiseptics and/or antibiotics in the prevention and treatment of periodontal diseases can lead to unwanted effects. Therefore, there is a need to develop novel antimicrobial strategies useful for the prevention and management of these diseases. Oral epithelial cells normally constitute a physical barrier that prevents infections, but bacterial adhesion to host tissues constitutes a first key step in the infectious process. With the final goal to elucidate the health properties of wine polyphenols at oral level, we studied their properties as an anti-adhesive therapy for periodontal and cariogenic prevention, as well as the combined action between wine polyphenols and oral probiotic strains in the management of microbial-derived oral diseases. In particular, we checked out the effect of two red wine polyphenols, as well as commercially available grape seed and red wine extracts, on bacteria that stick to teeth and gums and cause dental plaque, cavities and periodontal disease. Also, oral metabolism of polyphenols, including both oral microbiota and human mucosa cells, was investigated.  (more…)

Very GRATEFUL for them!” by Ashley Steel is licensed under CC BY 2.0Mahsa Nordqvist MD Department of Obstetrics and Gynecology Sahlgrenska University Hospital Gothenburg, Sweden  MedicalResearch.com: What is the background for this study? Response: We have shown in earlier observational studies that there is an association between probiotic intake and lower risk of preterm delivery and preeclampsia. Since pregnancy is a time of rapid change and different exposures can have different effect depending on the time of exposure, we wanted to find out if there is any special time point of consumption that might be of greater importance when it comes to these associations.

MedicalResearch.com Interview with: Dr Valerie Sung MBBS (Hons) FRACP MPH PhD Department of Paediatrics The University of Melbourne Murdoch Childrens Research Institute Parkville, Australia MedicalResearch.com: What is the background for this study? What are the main findings? Response: Infant colic is excessive crying in babies less than 3 months old with no underlying medical cause. It affects 1 in 5 newborns, is very distressing, and is associated with maternal depression, Shaken Baby Syndrome, and early cessation of breastfeeding. Up to now, there has been no single effective treatment for colic. The probiotic Lactobacillus reuteri DSM 17938 has recently shown promise but results from trials have been conflicting. In particular, a previous trial from Australia, the largest in the world so far, did not find the probiotic to be effective in both breastfed and formula-fed infants with colic. This international collaborative study, which collected raw data from 345 infants from existing trials from Italy, Poland, Canada and Australia, confirms Lactobacillus reuteri to be effective in breastfed infants with colic. However, it cannot be recommended for formula-fed infants with colic. Compared to a placebo, the probiotic group was two times more likely to reduce crying by 50 per cent, by the 21st day of treatment, for the babies who were exclusively breastfed. The number needed to treat for day 21 success in breastfed infants was 2.6. In contrast, the formula fed infants in the probiotic group seemed to do worse than the placebo group, but the numbers for this group were limited. (more…)

MedicalResearch.com Interview with: Emily G. Severance PhD Stanley Division of Developmental Neurovirology Department of Pediatrics Johns Hopkins University School of Medicine Baltimore, MD 21287 MedicalResearch.com: What is the background for this study? What are the main findings? Response: Previously, we found that people with schizophrenia and bipolar disorder had an increased susceptibility to Candida albicans yeast infections, which was sex specific and associated with memory deficits. Also in an earlier placebo-controlled probiotic study, we found that although probiotics improved the overall bowel function of people with schizophrenia, there was no effect by this treatment on psychiatric symptoms.  Given that C. albicans infections can upset the dynamics of the human microbiome, we decided to re-evaluate the potential benefit of probiotics in the context of a patient’s C. albicans yeast status.  Not only was bowel function again enhanced following intake of probiotics, but yeast antibody levels were decreased by this treatment. Furthermore, psychiatric symptoms were actually improved over time for men receiving probiotics who did not have elevated C. albicans antibodies. Men who were positive for C. albicans exposure, however, consistently presented with worse psychiatric symptoms irrespective of probiotic or placebo treatment. (more…)

MedicalResearch.com Interview with: Elizabeth Bryda, PhD Professor, Director, Rat Resource and Research Center Veterinary Pathobiology University of Missouri Columbia, Missouri MedicalResearch.com: What is the background for this study? What are the main findings? Response: A number of groups have demonstrated the ability of probiotics to benefit digestive health and there is a growing body of evidence to suggest an association between mental health and “gut health”. We were interested to see if probiotic bacteria could decrease anxiety- or stress-related behavior in a controlled setting using zebrafish as our model organism of choice for these studies. We were able to show that Lactobacillus plantarum decreased overall anxiety-related behavior and protected against stress-induced dysbiosis (microbial imbalance). The fact that administration of probiotic bacteria also protected other resident gut bacteria from the dramatic changes seen in “stressed” fish not receiving the probiotic was unexpected and suggested that these bacteria may be working at the level of the GI tract and the central nervous system.

MedicalResearch.com Interview with: Dr. Nicole Shen New York-Presbyterian/Weill Cornell Medical College MedicalResearch.com: What is the background for this study? Dr. Shen: Clostridium difficile infection (CDI) is a persistent, healthcare associated infection with significant morbidity and mortality that costs the US billions of dollars annually. Prevention is imperative, particularly for patients at high risk for infection – hospitalized adults taking antibiotics. Trials have suggested probiotics may be useful in preventing CDI. We conducted a systematic review with meta-analysis in this high-risk population, hospitalized adults receiving antibiotics, to evaluate the current evidence for probiotic use for prevention of CDI.

Dr. Ulla Uusitalo PhD University of South Florida, TampaMedicalResearch.com Interview with: Dr. Ulla Uusitalo PhD University of South Florida, Tampa Medical Research: What is the background for this study? What are the main findings? Dr. Uusitalo: The TEDDY Study is an international prospective cohort study with the primary goal to identify environmental causes of Type 1 Diabetes (T1D). It is carried out in six clinical research centers, in four countries: University of Colorado Health Science Center (US), Georgia Regents University (US), Pacific Northwest Diabetes Research Institute (US), Turku University Hospital (Finland), Institute of Diabetes Research (Germany), and Lund University (Sweden), since 2004. One possible environmental factor related to Type 1 Diabetes etiology is diet. Dietary supplements including probiotics as well as various types of infant formulas including probiotic fortified infant formula are studied. The microbial composition of gut has been shown to be associated with the development of  Type 1 Diabetes. Colonization of the infant gut starts already in utero and early microbial exposures have been found to be important in defining the trajectory of colonization. Probiotics have been demonstrated to induce favorable immunomodulation and it has been suggested that probiotic treatment could prevent T1D. Therefore we wanted to study the early exposures of probiotic and risk of islet autoimmunity, a condition often preceding Type 1 Diabetes. This study produced very interesting results. The main finding was that we found 60% decrease in the risk of islet autoimmunity among children with HLA genotype of DR3/4 (high risk), who were exposed to probiotics during the first 27 days of life.

Maria L Marco, PhD Associate Professor Department of Food Science & Technology Davis, CA 95616MedicalResearch.com Interview with: Maria L Marco, PhD Associate Professor Department of Food Science & Technology Davis, CA  95616 Medical Research: What is the background for this study? What are the main findings? Dr. Marco: Probiotics encompass certain strains of bacteria and yeast that when administered alive and in sufficient amounts can confer specific health benefits. Probiotics are increasingly added to foods, beverages, and intestinal supplements for delivery to the digestive tract. (Fermented) dairy products are currently the most popular food carriers for probiotic strains in clinical studies and commercial products. Although microorganisms generally respond quickly and adapt to their surrounding environments (e.g. in foods), the importance of the carrier format on probiotic function in vivo has yet to be systematically and mechanistically investigated. To address this need, we performed a couple studies in rodents to (i) examine whether probiotic Lactobacillus casei produces different proteins during low temperature (refrigeration) incubation in milk and (ii) measure whether incubation in milk is required for L. casei protection against inflammation. We found by shot-gun proteomics that L. casei does adapt for growth and survival in milk by producing a variety of (extra)cellular proteins, even at low-temperatures used to store dairy products prior to consumption. Such exposure of L. casei to milk was also essential for reducing the severity of disease in a mouse model of Ulcerative Colitis (UC), an inflammatory bowel disease characterized by continuous inflammation in the large intestine. Consuming milk alone also provided some protection against weight loss and intestinal inflammation in the Ulcerative Colitis mouse model but was not as effective as L. casei and milk in combination. Lastly, the importance of dairy for L. casei in preventing Ulcerative Colitis was confirmed by our findings that L. casei mutants lacking the capacity to synthesize proteins which are selectively produced during low-temperature incubation in milk were also impaired in preventing inflammatory responses in the intestine.

MedicalResearch.com Interview with: Laura Steenbergen Leiden University, Institute for Psychological Research, Cognitive Psychology Leiden, The Netherlands Medical Research: What is the background for this study? What are the main findings? Response: Food supplements, among which probiotics, are becoming more and more popular. A lot is known about the effect of probiotics on the physical functioning, but even though there are some rat studies on the effects of probiotics on mental well-being, not much is known about the effect in humans. The few studies on humans that are available show beneficial effects on mood when people experience a bad mood, or psychological distress. Worldwide, millions of people are suffering from mood disorders like for instance depression, but not everyone receives treatment for this. Research on probiotics has shown that they are safe and easily available, and we therefore wanted to investigate if probiotics could perhaps be promising in serving as a preventive or adjuvant therapy for mood disorders of anxiety or depression. We therefore focused on cognitive reactivity to sad mood, which measures the degree to which people activate dysfunctional thought patterns when experiencing a sad mood. This measure is known to be predictive of the onset and development of depression. Compared to subjects who received a 4-week placebo intervention, participants who received a 4-week multispecies probiotics intervention showed significantly reduced aggressive and ruminative thoughts. Even if preliminary, these results provide the first evidence that the intake of probiotics may help reduce negative thoughts associated with sad mood. As such, our findings shed an interesting new light on the potential of probiotics to serve as adjuvant or preventive therapy for depression. So if you are interested in taking probiotics then you could check out something like these probiotics in india. (more…)

MedicalResearch.com Interview with: Dr Kamal Ivory Institute of Food Research Norwich Research Park Norwich, UK Gut Health & Food Safety ISP The Institute of Food Research receives strategic funding from BBSRC MedicalResearch.com: What are the main findings of the study? Dr. Ivory: In the present study we show that administration of probiotics in the gut can induce changes at the nasal mucosa where the immune system meets pollen allergen. This implies a potential to alter the course of allergic rhinitis. However, in our single high dose pollen challenge in the clinic (out of pollen season), we did not measure any significant changes in the clinical parameters we had set. It is not clear if this was because a single challenge fails to replicate occurrence during natural seasonal exposure to pollen in terms of dosage and timing. That aside, the mode of action may vary from one probiotic organism to another and it is possible that a cocktail of probiotic organisms may be needed for clinical effectiveness. If funding becomes available, we would like to repeat the study during the pollen season. (more…)

 Australia MedicalResearch.com: What are the main findings of the study? Dr. Sung: The systematic review identified 12 studies (1825 infants)  that investigated the use of probiotics to treat or prevent infant colic (excessive crying of unknown cause in babies less than 3 months old). Three of the 5 treatment trials concluded probiotics effectively treat colic in breastfed babies; one suggested possible effectiveness in formula-fed babies with colic, and one suggested ineffectiveness in breastfed babies with colic. The three effective trials used the probiotic Lactobacillus reuteri in breastfed babies only; in two of these trials, the mothers were on a dairy-free diet. Five of the 7 prevention trials suggested probiotics to be ineffective in preventing colic. (more…)

MedicalResearch.com: What are the main findings of the study? Answer: Overall, diarrhoea occurred in just over 10% participants and diarrhoea caused by C. difficile in about 1%. These outcomes were equally common in those taking the microbial preparation and those taking placebo. Other outcomes (e.g. common GI symptoms, length of hospital stay, quality of life) were also much the same in the two groups. So, there was no evidence that the microbial preparation had prevented diarrhoea or had led to any other health benefit. In agreement with previous research, serious adverse events were also similar in the two groups – so we found no evidence that the microbial preparation caused any harm. (more…)

Dr. Pattani: We performed a meta-analysis of 16 studies that assessed the effectiveness of probiotics administered concurrently with antibiotics compared to the use of antibiotics alone. The use of probiotics among patients in these trials reduced the risk of antibiotic-associated diarrhea by almost 40% and decreased the rate of Clostridium difficile infection by 63%.
