Lactococcus lactis may reduce anxiety
In Vitro Probiotic and Antioxidant Potential of subsp. LL95 and Its Effect in Mice Behaviour.
Highly relevant findings on anxiety
We aimed to investigate how Lactococcus lactis subsp. LL95 affects anxiety and depression-like behaviors in mice. After administering LL95 orally for 28 days, we observed notable improvements in behavior. Mice showed less immobility in tests designed to measure depression and preferred open spaces, suggesting decreased anxiety levels. These findings highlight LL95's potential as a therapeutic probiotic, extending its benefits beyond gut health and showcasing its effects on mental well-being.

Lactobacillus anxiolytic effects proven
[Antioxidant and anxiolytic effect of and under conditions of normobaric hypoxia with hypercapnia].
High relevance for mental health
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.

Probiotic improves anxiety in mice
5-HT attenuates chronic stress-induced cognitive impairment in mice through intestinal flora disruption.
Moderate significance in findings
We examined how Lactococcus lactis E001-B-8 impacts anxiety in female mice under chronic stress conditions. Through a series of behavioral tests, we found that this probiotic not only helped improve cognitive function but also reduced anxiety-like behaviors.

Unlike traditional treatments like FLX, L. lactis was linked to better serotonin metabolism and healthier gut microbiome composition. This suggests that enhancing gut health could be a promising approach for anxiety management.

Probiotic alleviates IBS-D symptoms
A randomized double-blind, placebo-controlled trial to evaluate the safety and efficacy of live CECT 7347 (ES1) and heat-treated CECT 7347 (HT-ES1) in participants with diarrhea-predominant irritable bowel syndrome.
Highly relevant clinical findings
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
Interactions between symptoms and psychological status in irritable bowel syndrome: An exploratory study of the impact of a probiotic combination.
Study shows promising probiotic effects.
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.

Probiotics reduce anxiety in mice
Ameliorative effects of probiotics in AlCl-induced mouse model of Alzheimer's disease.
Highly relevant to Alzheimer's research
We explored how a combination of two probiotics, Lactobacillus rhamnosus GG and Bifidobacterium BB-12, affects anxiety in a mouse model of Alzheimer's disease. By conducting behavioral tests, we observed that probiotics significantly reduced anxiety-like behavior after exposure to aluminum chloride.

Furthermore, the treatment enhanced both spatial and recognition memory compared to the untreated group. Our findings illustrate that these probiotics can potentially alleviate anxiety and cognitive deficits linked with Alzheimer's disease through their influence on the gut-brain axis.

Bifidobacterium lactis reduces anxiety significantly
Bifidobacterium lactis Probio-M8 Adjuvant Treatment Confers Added Benefits to Patients with Coronary Artery Disease via Target Modulation of the Gut-Heart/-Brain Axes.
Highly relevant to gut-brain health
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.
