The Surprising Way Probiotics Can Improve Your Mood

Probiotics are beneficial bacteria that can be found in certain foods and supplements. They have been seen as a remedy for digestive health, but new research shows they have an impact on mental health as well.

The Gut-Brain Connection

The gut is often called our “second brain” because it contains millions of neurons. There is a bidirectional communication network between the gut and the brain via the vagus nerve, hormones and neurotransmitters. When we are stressed or anxious, our gut reacts by releasing stress hormones. This is why some people experience digestive issues during times of stress.

When we consume probiotics, they help balance the gut bacteria and improve gut health. This, in turn, sends positive signals to the brain via the vagus nerve and improves brain function. Probiotics also stimulate the production of neurotransmitters such as serotonin and GABA, which are crucial for regulating mood.

The Impact of Probiotics on Mental Health

Studies have shown that probiotics can lower levels of anxiety, depression and stress. In one study, participants who took probiotics for four weeks had significantly lower levels of depression and anxiety compared to those who took a placebo.

Another study showed that taking a probiotic supplement for three weeks improved mood and reduced cognitive reactivity to sad moods. Participants who took the probiotic had reduced inflammatory markers in their blood, suggesting that probiotics have an anti-inflammatory effect as well.

Which Probiotics are Best?

Not all probiotics are created equal. Different strains have different effects on the body. The two most common strains of probiotics are lactobacillus and bifidobacterium. Both have been shown to be effective in improving mental health.

Lactobacillus rhamnosus GG is one of the most well-researched strains of probiotics. It has been shown to improve mood and reduce symptoms of anxiety and depression. Bifidobacterium longum has also been shown to be effective in improving mental health and reducing stress levels.

It is important to note that the effectiveness of a probiotic supplement depends on several factors such as the quality of the supplement, the dosage and the individual’s gut microbiome. It is best to consult with a healthcare professional before starting a probiotic supplement.

Probiotics in Food

Probiotics can also be found in certain foods. Fermented foods such as yogurt, kefir, sauerkraut, kimchi and kombucha contain live bacteria that can help improve gut health. Make sure to choose non-sweetened, non-artificially sweetened options, and keep in mind that many fermented foods can be high in sodium.

The Takeaway

Probiotics have been shown to improve digestive health for years, but recent research shows they also have an impact on mental health. Probiotics can improve mood, reduce anxiety and depression, and even lower stress levels. It is important to choose high-quality probiotics and/or consume probiotics through fermented foods to reap the benefits.
