There is a saying that goes, “the gut is the second brain.” It may sound strange, but science has revealed that the connection between the gut and the brain is strong and bi-directional. This is why researchers have begun exploring the potential link between probiotics and mental health. Probiotics are beneficial bacteria that live in the human gut and provide various health benefits. They have become extremely popular in recent years due to their potential to improve digestive health, boost the immune system, and even improve mental wellbeing.
The gut-brain connection
The enteric nervous system (ENS) is the network of neurons that governs the function of the gastrointestinal tract. Although the ENS lies in the gut, it is deemed the second brain because of its connection to the brain through the vagus nerve. This means that the gut and the brain regularly communicate, sending signals to each other that can affect mood, cognition, and behavior.
How probiotics may influence mental health
The gut microbiome is composed of trillions of microorganisms, including bacteria, viruses, fungi, and protozoa. These microorganisms play an essential role in modulating the immune response, regulating inflammation and oxidative stress, and synthesizing vitamins and neurotransmitters. Among those microorganisms, certain strains of bacteria have been shown to influence mental health positively.
Scientific evidence supporting the use of probiotics for mental health
Several clinical studies have demonstrated the effectiveness of specific probiotics in improving mental health. For example, a systematic review of 10 studies found that probiotic supplementation may have a positive effect on symptoms of depression and anxiety. Another study found that supplementing with Lactobacillus acidophilus and Bifidobacterium bifidum for four weeks resulted in a significant reduction in psychological distress among healthy volunteers.
Best probiotic strains for improving mental wellbeing
While many probiotic strains may offer various health benefits, some strains are considered best for enhancing mental health. Here are some of the most effective strains:
– Lactobacillus helveticus: This probiotic strain has been shown to reduce symptoms of depression and anxiety and improve mood.
– Bifidobacterium bifidum: This strain has demonstrated efficacy in alleviating symptoms of anxiety and stress-related disorders.
– Lactobacillus rhamnosus: This probiotic strain has been shown to have a positive effect on mood, helping to alleviate symptoms of anxiety and depression.
Closing paragraph
In conclusion, the science behind the gut-brain connection and probiotics’ influence on mental health is still in its infancy. However, preliminary studies have shown promising results, suggesting that probiotic supplementation can help alleviate symptoms of depression, anxiety, and other mental health disorders. As always, it is essential to talk to a healthcare professional before starting any new supplement, particularly if you are taking medication or have any underlying health conditions.
