Lactobacillus shows promise for IBS
We assessed the effectiveness of a probiotic blend of two Lactobacillus strains in treating diarrhea-predominant irritable bowel syndrome (IBS-D) through a randomized, single-blinded trial. Involving 100 patients, one group received standard IBS treatment while the other added probiotics.

After 12 weeks, both groups experienced symptom relief, but the probiotic group showed a greater decrease in their IBS symptoms. Remarkably, all patients on probiotics either found complete symptom relief or had mild symptoms, compared to over 14% of those on standard treatment who still experienced moderate IBS.

Effective treatment for IBS-C
We aimed to understand how Lacticaseibacillus rhamnosus IDCC 3201 (RH 3201) affects irritable bowel syndrome with constipation (IBS-C) through a thorough study. In a randomized, double-blind trial, 30 participants took either RH 3201 or a placebo for 8 weeks.

Those taking RH 3201 experienced significant improvements, including fewer bowel discomforts and reduced bloating issues. We also observed an increase in certain beneficial gut bacteria and a link between specific metabolites and symptom relief. Overall, RH 3201 shows promise as an effective treatment for IBS-C.

We evaluated how the probiotic Neobiotic Lactobalance® can help patients with irritable bowel syndrome (IBS) experiencing diarrhea and those suffering from antibiotic-associated diarrhea (AAD). Over a 21-day period, 54 participants took one capsule daily.

The results were promising, as symptoms like abdominal pain and diarrheal disorders significantly improved. Patients experienced a notable drop in symptom severity, and beneficial changes in gut bacteria were also observed.

Overall, Lactobalance® appears to support a healthier gut microbiome and alleviate symptoms for these patients.

Improved bowel movements
5 people found this helpful
A urine test revealed a bacterial reaction, so I began taking this. Although I'm unsure of the long-term effects yet, I prefer to avoid antibiotics if possible and hope Acidophilus will assist. I've experienced an immediate improvement in my bowel movements. For years, I dealt with loose stools and constipation, but now I feel well each day when I drink this. The small grain size makes it easy to consume.

Quick bowel relief
5 people found this helpful
Many recommended this probiotic for vaginal inflammation, and I saw a difference just two days in. The discharge has significantly reduced, and it doesn't require refrigeration. They are small, tasteless, and easy to swallow, and I've experienced smooth bowel movements the next morning. I intend to continue taking it for maintenance.

Probiotic and trimebutine therapy effective
Our evaluation focused on the effectiveness of combining probiotics with trimebutine for treating irritable bowel syndrome (IBS). Through a systematic review of 37 randomized controlled trials involving 4,360 participants, we found that this combination therapy significantly outperformed trimebutine alone.

The effective rate was an impressive 93.5% for those receiving both treatments compared to just 73.8% for trimebutine alone. Notably, while side effects were mild in both groups, the combination therapy displayed a favorable safety profile. This suggests that using specific probiotic strains can enhance the treatment outcome for individuals with IBS.

Probiotics support intestinal health
We assessed how a multi-strain probiotic, Serobioma, affects gut health in individuals with Irritable Bowel Syndrome (IBS). This study involved IBS patients and healthy controls, looking at how Serobioma interacts with mucosal mediators from IBS patients' biopsies.

Remarkably, Serobioma improved the integrity of intestinal cell layers affected by IBS mediators, particularly in patients with diarrhea and mixed bowel habits. It successfully countered increased permeability, indicating its potential to support gut barrier function in IBS.

Synbiotic reduced IBS pain effectively
We explored the effects of a new synbiotic combination of chitin-glucan (CG) and NCFM in a rat model of irritable bowel syndrome (IBS).

After nine weeks, we found that both CG and NCFM reduced abdominal pain when used separately, but together, they significantly lessened visceral pain and intestinal inflammation.

Not only did this combination improve pain perception, but it also reduced colon lesions and inflammation markers. Overall, our findings suggest that this synbiotic approach holds promise for alleviating IBS symptoms.

Bowel improvement noted

Last year, I suffered repeated bacterial vaginosis leading to pyelonephritis and hospitalisation. To avoid long-term antibiotics, I tried this supplement. Since starting it, my vaginal discharge improved, and unexpectedly, my bowel movements have also enhanced. I used to struggle with hemorrhoids in winter, but I’ve been fine this year. I've realised just how crucial bacterial balance is for health.

Probiotics show IBS symptom relief
We conducted a thorough review to assess how different treatments, like probiotics, prebiotics, synbiotics, and fecal microbiota transplantation, affect irritable bowel syndrome (IBS) symptoms.

Our analysis involved 54 studies on probiotics, where we discovered clear improvements in IBS symptoms, particularly with certain strains. However, prebiotics and synbiotics did not demonstrate significant benefits.

The network meta-analysis highlighted that probiotics and fecal microbiota transplantation are promising options for managing IBS, although the best probiotic strain remains uncertain.

Probiotic and trimebutine therapy effective
Our evaluation focused on the effectiveness of combining probiotics with trimebutine for treating irritable bowel syndrome (IBS). Through a systematic review of 37 randomized controlled trials involving 4,360 participants, we found that this combination therapy significantly outperformed trimebutine alone.

The effective rate was an impressive 93.5% for those receiving both treatments compared to just 73.8% for trimebutine alone. Notably, while side effects were mild in both groups, the combination therapy displayed a favorable safety profile. This suggests that using specific probiotic strains can enhance the treatment outcome for individuals with IBS.
We examined the effectiveness of Lactobacillus and other probiotics in treating irritable bowel syndrome (IBS) through a thorough review of 82 clinical trials involving over 10,000 patients. The results indicated that while some probiotics, particularly certain Escherichia strains, showed moderate benefits for general symptoms, the effectiveness of Lactobacillus strains was generally rated as low to very low. Importantly, the risk of adverse events did not increase significantly with probiotic use. Overall, evidence supporting probiotics for IBS remains uncertain.

Probiotics effective for IBS relief
We aimed to explore the effectiveness of probiotics in managing irritable bowel syndrome (IBS). By reviewing 52 rigorous trials with nearly 6,300 participants, we found that probiotics significantly enhanced overall symptom relief, improved subjective well-being, and alleviated abdominal pain.

Notably, a daily dose of 10 billion cfu seemed particularly beneficial, with effects visible as early as four weeks into treatment. While probiotics demonstrated clear advantages, the roles of prebiotics and synbiotics remain less certain due to limited studies.
7
Lactobacillus rhamnosus shows positive IBS effects
We explored how a mix of Lactobacillus probiotics, including Lactobacillus rhamnosus, could help improve symptoms of irritable bowel syndrome (IBS) in a study involving 113 participants.

Participants took either the probiotic or a placebo for 12 weeks, with results showing that those on the active treatment experienced significant relief in several areas, particularly in managing pain and enhancing quality of life.

The most notable improvements were seen in women and those with diarrhea-predominant IBS. While some subjects reported mild adverse effects, serious complications were absent, confirming the treatment's safety.
