We explored how the treatment with JB-1—a type of probiotic bacteria—affects anxiety during chronic stress in rats. In our study, half of the twenty rats received JB-1 while the other half got a placebo over eight weeks of stress exposure.
The results were telling! Rats on JB-1 showed less anxiety and were more willing to explore their environment compared to the placebo group, which largely avoided exploration. Additionally, measurements of brain metabolites indicated that JB-1 helped maintain stability in brain chemistry, even in stressful conditions.
This suggests that lactobacillus rhamnosus might play a beneficial role in reducing anxiety during prolonged stress.

We investigated the impact of Lactobacillus acidophilus and Bifidobacterium adolescentis on anxiety levels in rats facing acute hypoxia. In our study, 64 male Wistar rats were divided into four groups for comparison. The results showed that rats receiving probiotics exhibited lower oxidative stress and anxiety levels compared to those who did not. Notably, those treated with probiotics went through behavioral tests indicating increased exploratory behavior and decreased anxiety. Overall, our findings suggest that these probiotics offer both antioxidant and anxiety-reducing effects in stressful conditions.

We examined how colonizing newborn mice with probiotics, specifically Lactobacillus rhamnosus GG (LGG), influences anxiety in adulthood. By administering live LGG during pregnancy and early life, we observed significant changes to the gut microbiome and protective effects on the intestinal barrier. Notably, the adult mice with LGG colonization showed reduced anxiety-like behaviors in tests designed to measure stress responses. This indicates that early life probiotics could play an important role in regulating the gut-brain axis and improving mental health in later life.

Calm and sleep
109 people found this helpful
This probiotic is fantastic! I've used it for about two years, initially to address constipation and withdrawal symptoms from valerian. It significantly calmed my anxiety and improved my sleep, especially when taken with a glass of wine before dinner. It also helped lower my blood pressure, which often spikes in stressful situations. After taking it during a stressful work moment, I felt calm and relieved a headache within hours. I'm thrilled to have found this probiotic!

Decreased anxiety

I took this for a year or two, assuming more was better due to its 50 billion CFUs. However, testing revealed my gut diversity was in the bottom 5% because of taking just this probiotic. After switching to custom probiotics from Viome, I've experienced notably less anxiety, even amidst significant work stress. These probiotics might be beneficial for a limited time, but long-term, a variety of options may be preferable.

We investigated how probiotics, specifically Lactobacillus rhamnosus and Bifidobacterium BB-12, can affect anxiety in a mouse model of Alzheimer’s disease. In our study, we found that mice treated with these probiotics exhibited significantly reduced anxiety-like behaviors compared to those exposed to aluminum chloride alone.
Through various behavioral tests, it was evident that this probiotic combination also improved memory functions. Our results suggest that leveraging the gut-brain axis through these probiotics could offer a promising approach for alleviating anxiety and cognitive deficits in neurodegenerative conditions like Alzheimer's.

We conducted a study to assess how well the probiotic CECT 7347 (ES1) and the heat-treated version (HT-ES1) helped alleviate diarrhea-predominant irritable bowel syndrome (IBS-D) symptoms in adults. Over 84 days, participants took either the probiotic, the postbiotic, or a placebo, reporting significant improvement in key measures like symptom severity, quality of life, and even anxiety levels. The results demonstrated a notable reduction in IBS symptoms, making it one of the first trials to show such effectiveness in this area.

Bifidobacterium longum may ease anxiety
We examined the impact of a probiotic blend, Bifidobacterium longum strains 1714® and 35642®, on anxiety and irritable bowel syndrome (IBS) symptoms in patients. Over eight weeks, we observed that the treatment helped restore the stress response and improved IBS symptoms and psychometric scores for anxiety and depression.
Interestingly, the benefits continued after stopping treatment, suggesting a lasting positive effect. The findings indicate that managing stress can significantly influence IBS symptoms and associated mood disturbances.

Bifidobacterium lactis reduces anxiety significantly
We conducted a thorough investigation into the effects of Bifidobacterium lactis, known as Probio-M8, on anxiety and overall well-being in patients with coronary artery disease (CAD). Over six months, we compared a group receiving the probiotic with a placebo group.
Notably, those in the probiotic group reported significant improvements in anxiety levels and other markers of mental health. This suggests that enhancing gut health can also positively influence our mood and emotional states.
With ongoing research, it’s becoming clearer how beneficial our gut bacteria can be for our overall mental and physical wellness.
