Probiotics have become a popular topic in the health industry for their potential to aid in digestion and improve immune function. But did you know that these live microorganisms can also have an impact on mental health?
The gut has often been referred to as the “second brain.” This is because it is home to the enteric nervous system, which is responsible for regulating the digestive system. However, this system also communicates with the central nervous system, which controls mood and behavior. This connection between the gut and brain is known as the gut-brain axis.
Research has shown that the gut microbiome, which is made up of trillions of microbes, plays a key role in this communication process. In fact, some studies have suggested that the gut microbiome may influence the development and function of the brain in early life, as well as throughout adulthood.
So, how exactly can probiotics help with mental health issues?
Reducing Symptoms of Depression and Anxiety
Depression and anxiety are two of the most common mental health disorders. While there are many factors that can contribute to the development of these conditions, research has shown that gut health may be one of them.
Some studies have found that people with depression or anxiety have an imbalance in their gut microbiome, with lower levels of certain beneficial bacteria. Other research has shown that supplementing with certain probiotic strains, such as Lactobacillus helveticus and Bifidobacterium longum, can help reduce symptoms of depression and anxiety.
In a 2017 study published in the Journal of Clinical Psychopharmacology, researchers found that people with major depressive disorder who took a probiotic supplement experienced a significant reduction in their symptoms compared to those who took a placebo.
Improving Cognitive Function
Cognitive function refers to mental processes such as learning, memory, and decision-making. While cognitive decline is a normal part of aging, some people may experience more severe impairment, such as dementia.
Research has suggested that the gut microbiome may play a role in cognitive function and decline. Studies have found that mice who were raised in a sterile environment (without gut microbes) had poorer cognitive performance compared to those with a normal microbiome. Other studies have found that supplementing with certain probiotics can improve cognitive function and memory in both humans and animals.
Reducing Symptoms of Autism Spectrum Disorder
Autism spectrum disorder (ASD) is a developmental disorder that affects communication and behavior. While the exact causes of ASD are not yet fully understood, research has suggested that gut health may play a role.
Some studies have found that children with ASD have an altered gut microbiome compared to those without the disorder. Other research has shown that supplementing with certain probiotics, such as Lactobacillus acidophilus and Bifidobacterium bifidum, can help reduce symptoms of ASD and improve social behavior.
Conclusion
The potential benefits of probiotics for mental health are still being studied, but the research so far has been promising. Probiotics may be a safe and natural way to support gut health and improve mood, cognitive function, and behavior.
If you are considering taking a probiotic supplement, it is important to speak with your healthcare provider first. Not all probiotics are created equal, and certain strains may be more effective for certain conditions than others. Your healthcare provider can help you determine which probiotic supplement is right for you.
