Wonders of Probiotics: How They Can Improve Mental Health?
Probiotics are live microorganisms that provide several health benefits when consumed in adequate amounts. They are naturally found in our gut microbiome, but we can also get them from supplements and fermented foods such as yogurt, kefir, and kimchi.
While most people associate probiotics with digestive health, there is growing evidence suggesting that these beneficial bacteria can also improve mental health. Let’s explore how:
Probiotics and Depression
Depression is a common mental health disorder that affects millions of people worldwide. Recent studies have found that probiotics can reduce symptoms of depression by modulating the gut-brain axis. The gut-brain axis is a powerful connection between our gut microbiome and our central nervous system.
Probiotics can influence the production of neurotransmitters, such as serotonin and dopamine, which play a crucial role in regulating mood and emotions. A study published in the journal Gastroenterology found that a probiotic supplement containing Bifidobacterium and Lactobacillus strains improved symptoms of depression and anxiety in patients with irritable bowel syndrome.
Another study conducted in patients with major depressive disorder found that a daily probiotic supplement improved symptoms of depression and increased quality of life compared to placebo.
Probiotics and Anxiety
Similar to depression, anxiety is a common mental health disorder that can have a significant impact on one’s quality of life. Studies have found that probiotics may also have an anxiolytic effect, meaning they can reduce symptoms of anxiety.
A study published in the journal Frontiers in Psychiatry found that a multispecies probiotic supplement reduced symptoms of anxiety and depression in patients with generalized anxiety disorder. Another study conducted in healthy individuals found that a probiotic yogurt containing Lactobacillus helveticus and Bifidobacterium longum strains reduced cortisol levels and improved mood and cognition under stress.
Probiotics and Stress
Stress is a natural response to challenging situations, but chronic stress can have negative effects on mental health. Probiotics may help regulate the stress response by modulating the hypothalamic-pituitary-adrenal axis, which is involved in the production of stress hormones.
A study published in the journal Brain, Behavior, and Immunity found that a probiotic supplement containing Lactobacillus helveticus and Bifidobacterium longum strains reduced cortisol levels and subjective stress in healthy volunteers exposed to an acute stressor.
Conclusion
Probiotics are a promising area of research for mental health and well-being. While more studies are needed to fully understand their mechanisms of action, current evidence suggests that they can improve symptoms of depression, anxiety, and stress.
If you’re interested in incorporating probiotics into your diet, fermented foods such as yogurt, kefir, and kimchi are excellent sources. Alternatively, you can also consider taking a probiotic supplement with a variety of strains to support your gut and brain health.
