BLa80 shows promise for constipation
subsp. BLa80 alleviates constipation in mice through modulating the stem cell factor (SCF)/c-Kit pathway and the gut microbiota.
Relevance score indicates high potential
We explored the impact of Bifidobacterium lactis BLa80 on constipation using mice that were induced with functional constipation through loperamide treatment. In our study, we compared BLa80 to a blank group and a positive control.

The results indicated that BLa80 improved intestinal movement, increased fecal moisture, and balanced gut bacteria. It also helped regulate important gut hormones. Overall, BLa80 shows promise as a potential new option for relieving constipation in functional foods.

Bifidobacterium lactis alleviates constipation
subsp. TG11 ameliorates loperamide-induced constipation in mice by modulating gut microbiota.
Relevant animal model study
We investigated the effects of Bifidobacterium lactis subsp. TG11 on loperamide-induced constipation in mice. The mice were grouped into control and treatment categories, receiving different doses of the probiotic.

After treatment, those receiving TG11 showed improved intestinal motility and maintained better fecal water content. Notably, the probiotic also positively affected gut microbiota, increasing beneficial bacteria and promoting short-chain fatty acid production.

Overall, Bifidobacterium lactis TG11 appears effective in alleviating constipation, potentially by enhancing gut health.

Bifidobacterium lactis improves constipation
Adjunctive efficacy of Bifidobacterium animalis subsp. lactis XLTG11 for functional constipation in children.
High relevance for children's health
We assessed the effectiveness of Bifidobacterium animalis subsp. lactis XLTG11 in helping children with functional constipation through a well-structured study with a randomized, double-blinded, placebo-controlled design. The children were split into two groups: one received the probiotic treatment alongside conventional care, while the other did not.

Over the treatment period, we saw a consistent increase in bowel movements in the group taking the probiotic, showing higher fecal frequency compared to the control group. Additionally, the beneficial bacteria in their guts improved, which suggests that this treatment is a promising approach for managing constipation in children.

Positive GI health
Excellent product! As a pharmacist, I find this one of the best probiotics available. Within two days of taking it, my gastrointestinal health improved significantly. I experienced reduced indigestion, bloating, and both constipation and diarrhoea. There are other effective products, but they are often pricier with less quantity.

Lactobacillus improves IBS-C symptoms
Clinical assessment and cytokines level in constipation-predominant irritable bowel syndrome participants treated with Lactobacillus-containing cultured milk drink.
Consistent findings support treatment benefit
We investigated how a cultured milk drink containing Lactobacillus acidophilus affects symptoms of constipation in individuals with irritable bowel syndrome (IBS-C). Over 30 days, participants consumed the drink daily.

At the end of the study, an impressive 97.4% of IBS-C participants reported improvement in their constipation-related symptoms. We also noticed reductions in intestinal transit time and pro-inflammatory cytokines linked to IBS. Overall, this suggests that including this cultured milk drink may be a beneficial addition to IBS-C treatment plans.

Probiotics improve constipation symptoms
Impact of a probiotic chewable tablet on stool habits and microbial profile in children with functional constipation: A randomized controlled clinical trial.
High relevance to childhood constipation.
We conducted a randomized, placebo-controlled trial involving 92 children aged 4 to 12 with functional constipation. Over four weeks, we provided one group with a probiotic chewable tablet containing specific strains and compared their experiences to a placebo group.

The findings were promising; the probiotic group reported a significant improvement in stool frequency and a decrease in hard defecation. Specifically, hard stools decreased from 43% to 14%, while normal defecation increased from 56% to 80%. This study highlights the potential of probiotics as a valuable option for managing constipation in children.

Probiotics improve constipation symptoms
Effects of Fermented Milk with Mixed Strains as a Probiotic on the Inhibition of Loperamide-Induced Constipation.
Relevant for constipation treatment
We evaluated how lactobacillus acidophilus, both alone and in a mix with other bacteria, might relieve constipation caused by loperamide in rats. Over 14 days, we noticed that the groups receiving probiotics had significantly heavier and wetter stools compared to control animals.

Notably, the CKDBP group, a blend of multiple bacteria, showed the greatest improvement in intestinal transit. Measures like mucosal length and mucus secretion were also significantly enhanced in all probiotic-treated groups, highlighting their potential to alleviate constipation symptoms effectively.

Bifidobacterium aids childhood constipation
Adjunctive efficacy of Bifidobacterium animalis subsp. lactis XLTG11 for functional constipation in children.
Clinical importance of probiotic use
We investigated the impact of Bifidobacterium animalis subsp. lactis XLTG11 on functional constipation in children using a randomized, double-blind, placebo-controlled design.

Our findings showed that children receiving this probiotic experienced a significant increase in their weekly fecal frequency compared to those on conventional treatment without probiotics.

Additionally, the introduction of XLTG11 altered gut microbiota positively and influenced the metabolism of short-chain fatty acids. These results suggest that Bifidobacterium can benefit children suffering from constipation.

B. longum W11 aids constipation relief
Bifidobacterium longum W11: Uniqueness and individual or combined clinical use in association with rifaximin.
Highly relevant clinical findings
We explored the effectiveness of Bifidobacterium longum W11 in treating constipation, particularly in patients with irritable bowel syndrome (IBS). Our research included rigorous reviews and clinical trials, one of which was randomized and placebo-controlled.

The findings were promising—B. longum W11 significantly reduced constipation symptoms, especially in those experiencing reduced gut motility due to calorie-restricted diets.

Additionally, its non-transmissible antibiotic resistance may offer advantages when used alongside antibiotics like rifaximin, showing improved outcomes in certain conditions like diverticular disease.
