Anxiety and depression are two of the most common mental health disorders that have debilitating effects on a person’s life. Fortunately, there’s a growing body of research that suggests that probiotics could help alleviate some of the symptoms associated with these conditions.
What are Probiotics?
Probiotics are live microorganisms found in fermented foods or supplements. They are often referred to as “good bacteria,” as they are believed to have numerous health benefits. Probiotics work by restoring the natural balance of bacteria in the gut, which can get disrupted due to a poor diet, stress, age, or taking antibiotics. When this happens, harmful bacteria can take over and cause health problems.
Probiotics and Mental Health
The human gut is sometimes referred to as the “second brain” due to the complex relationship between the gut and the brain. The gut contains approximately 100 trillion microorganisms, including bacteria, viruses, and fungi. The gut microbiome plays a critical role in regulating many bodily functions, including digestion and the immune system. But, recent research has linked the gut microbiome to mental health as well.
Studies have shown that people with depression and anxiety tend to have different gut bacteria profiles than those without these conditions. Furthermore, research has found that probiotics may help alleviate some of the symptoms associated with anxiety and depression.
Probiotics and Anxiety
Anxiety is a mental health disorder characterized by excessive worry and fear. It can lead to physical symptoms like rapid heart rate, sweating, and trembling. Studies have shown that probiotics could help alleviate some of the symptoms associated with anxiety.
One study published in the journal Psychiatry Research found that participants who took a probiotic supplement for four weeks experienced reduced levels of anxiety. Another study published in the journal Gastroenterology found that participants who took a daily probiotic supplement for four weeks had decreased activity in the areas of the brain associated with anxiety.
Probiotics and Depression
Depression is a mental health disorder characterized by a persistent feeling of sadness and a loss of interest in activities that a person once enjoyed. Research has found that probiotics may help alleviate some of the symptoms associated with depression.
One study published in the journal Nutritional Neuroscience found that participants who took a probiotic supplement for four weeks had significantly decreased symptoms of depression compared to the placebo group. Another study published in the journal BMJ Open found that participants who consumed a fermented milk product containing probiotics had reduced levels of depression and anxiety compared to those who consumed a placebo.
How Probiotics Work
Researchers are still working to understand how probiotics work to alleviate anxiety and depression. However, there are several theories. One theory is that probiotics increase the production of neurotransmitters in the brain, such as serotonin and dopamine. These neurotransmitters play a critical role in regulating mood, and imbalances have been linked to depression and anxiety.
Another theory is that probiotics reduce inflammation in the gut and throughout the body. Inflammation has been linked to a number of health conditions, including mental health disorders like depression and anxiety.
Conclusion
Probiotics are a promising area of research for treating anxiety and depression. While more research is needed to fully understand how probiotics work, the evidence suggests that they could be a safe and effective way to alleviate some of the symptoms associated with these conditions.
If you’re experiencing symptoms of anxiety or depression, it’s important to talk to a healthcare professional. Probiotics are not a substitute for professional treatment.
