The Surprising Relationship Between Probiotics and Mental Health
Probiotics are widely known for their role in gut health and digestive issues. These tiny microorganisms are live bacteria and yeasts that are beneficial for our bodies, especially our digestive system. However, recent studies have shown that certain strains of probiotics may also benefit our mental health. In this article, we’ll explore the relationship between probiotics and mental health in more detail.
What are probiotics?
Probiotics are live microorganisms that are beneficial for human health. They are found naturally in our gut and are present in certain foods such as yogurt, kefir, kimchi, sauerkraut and pickles. Probiotics work by helping to balance the ‘good’ and ‘bad’ bacteria in our gut, supporting the digestive system and helping to reduce inflammation.
How do probiotics impact our mental health?
Over the past few years, scientists have discovered that the gut-brain axis is a complex two-way communication highway. Therefore, the health of our gut is closely connected to the health of our brain. The gut is where around 90% of our serotonin – a chemical that regulates mood – is produced. Furthermore, the gut houses the enteric nervous system (ENS), also referred to as the ‘second brain.’
Research shows that the state of our gut microbiota can positively or negatively affect our mood and mental health. According to a study published in the Journal of Neurogastroenterology and Motility, an unhealthy gut microbiome may lead to various psychiatric disorders. So, taking probiotics and restoring the balance of beneficial bacteria in the gut could help improve symptoms of anxiety, depression, and stress.
Which strains of probiotics are beneficial for mental health?
Not all probiotics are created equal, and not all strains have the same effect on our mental health. Research suggests that certain strains may be more beneficial than others. Here are a few strains that have been shown to have a positive impact:
- Lactobacillus rhamnosus – In a study published in the journal Neuropsychopharmacology, participants who consumed L. Rhamnosus had a reduced stress response and improved mood compared to those who did not consume it.
- Bifidobacterium longum – Studies have shown that consuming B. longum can improve cognitive function and reduce symptoms of depression and anxiety.
- Lactobacillus helveticus and Bifidobacterium bifidum – These strains have been shown to reduce symptoms of depression and anxiety, according to a study published in the Journal of Psychiatric Research.
Should you take probiotics for mental health?
While probiotics have shown promising results, it’s important to remember that they should not replace prescribed medication or traditional mental health treatments. Instead, they should be used as a complementary addition to a healthy lifestyle, including a balanced diet, regular exercise, and good sleep hygiene. It’s best to talk to your healthcare provider before starting any new supplements, including probiotics. Additionally, it’s important to choose high-quality probiotics that have been clinically researched and have a good reputation in the market.
Conclusion
Probiotics are no longer just beneficial for gut health, but also for mental health. The role of our gut microbiota is still being researched, but studies suggest that it plays a significant role in our overall health, including our mental wellbeing. If you’re considering taking probiotics to improve your mental health, talk to your healthcare provider first and choose high-quality strains that have been clinically researched.
