Introduction
When we think of probiotics, we often think of their ability to improve our digestive health. However, research has shown that probiotics can also have a positive impact on our mental health. In this article, we will explore the surprising benefits of probiotics for mental health.
What are Probiotics?
Probiotics are live bacteria and yeasts that are good for our health, especially our digestive system. They are often referred to as ‘good’ bacteria as they help keep our gut healthy by eliminating harmful bacteria that can cause infections and other health problems.
How Probiotics Affect Our Mental Health
The gut-brain connection is a well-known concept where there is two-way communication between the gut and the brain. Probiotics can positively impact the gut-brain connection, leading to beneficial effects on our mental health.
Reducing Anxiety
Anxiety disorders are among the most common mental health disorders worldwide. Studies have shown that probiotics can help reduce anxiety levels and improve symptoms of anxiety disorders, such as Generalized Anxiety Disorder (GAD) and Social Anxiety Disorder (SAD).
One study found that taking a probiotic supplement for 30 days significantly reduced symptoms of GAD in participants. Another study found that probiotics help reduce social anxiety in people with Irritable Bowel Syndrome (IBS).
Managing Depression
Depression is a common mental health disorder that affects millions of people worldwide. Research has shown that probiotics can help manage depression and improve symptoms.
A study conducted on patients with major depressive disorder found that taking a probiotic supplement for 8 weeks resulted in significant improvement in depressive symptoms. Another study found that a specific strain of probiotics called Bifidobacterium longum NCC3001 can help manage depressive symptoms in patients with Irritable Bowel Syndrome (IBS).
Improving Cognitive Function
Cognitive function refers to our ability to think, process information, and make decisions. Probiotics have been found to improve cognitive function in both healthy individuals and those with cognitive impairment.
A study conducted on healthy adults found that taking a probiotic supplement for four weeks improved cognitive function, including memory and processing speed. Another study found that a specific strain of probiotics called Lactobacillus helveticus and Bifidobacterium longum can improve cognitive function in patients with Alzheimer’s disease.
The Best Probiotic Strains for Mental Health
Not all probiotic strains have the same benefits for mental health. Some of the best probiotic strains for mental health include:
- Lactobacillus acidophilus: Can improve symptoms of depression and anxiety.
- Bifidobacterium bifidum: Can improve cognitive function and reduce symptoms of depression and anxiety.
- Lactobacillus rhamnosus: Can reduce symptoms of anxiety and improve cognitive function in healthy adults.
- Bifidobacterium longum: Can improve symptoms of depression and anxiety in patients with IBS.
Conclusion
Probiotics have been found to have surprising benefits for our mental health, including reducing symptoms of anxiety and depression and improving cognitive function. While research is still ongoing, it is clear that incorporating probiotics into our diet or taking supplements can have a positive impact on our mental health.
