Improve your mood naturally using your gut microbiome

Did you know that gut bacteria might be a cause of depression and anxiety? On the other hand, “good” bacteria can help improve your mood naturally! Researchers have discovered that improving the composition of the gut microbiome can help people with mood disorders.

Are you searching for natural ways to improve your mood? On the days you’re feeling down, there are certain things you can do. Here we highlight what science has discovered about the mood-boosting properties of your microbiome. 

Gut bacteria and mental wellbeing

There is sufficient evidence that the microbial composition of your gut matters for your current mental state and that a poor gut microbiome affects your mood. 

A study from China discovered that patients with depression had less of “good” bacteria in their gut compared to healthy individuals¹. Another study has found that patients with severe depression had a reduced “richness” of the microbiome (i.e. the number of different bacteria groups) and low levels of the large bacteria group called Faecalibacterium².

So if a poor microbiome can increase likelihood of depression, can a healthy one improve your mental wellbeing? Some of the novel treatment approaches are now targeting gut microbiota to prevent and treat symptoms of mood disorders. They are based on evidence that improvement to the composition of the gut microbiome can also contribute to your mental wellbeing. GUTXY has listed the most promising interventions below.

Can probiotics improve your mood?

Probiotic supplements are designed to restore abundance and diversity of patients’ gut microbiota. In 2016 scientists observed significant improvement in the mental health of petrochemical workers that consumed probiotics for 6 weeks. They were less stressed, anxious and depressed³. Participants of another study became less sad after taking probiotic supplements⁴.

Lactobacillus and Bifidobacterium containing probiotics have demonstrated antidepressant activity and an ability to inhibit anxiety. 

• Lactobacillus rhamnosus hn001: prevention and treatment of post-partum depression⁵.
• Lactobacillus helveticus ns8: alleviated chronic stress.
• Bifidobacterium longum 1714: antidepressant.
• Bifidobacterium breve 1205: lowered anxiety. 

A recent extensive study concluded that probiotics have the potential to reduce the risk of depression by way of effects similar to drugs currently used in treating mood disorders⁶.

Use of dietary treatment as an adjunct or sole therapy for mood disorders is not beyond the realm of possibility⁷.

Natural stress prevention with a prebiotic diet

Poor diet can have a significant impact on your microbiome and your mood. Instead of resorting to medicine to get rid of unhealthy intestinal flora, you can try and improve your microbiome naturally with a diet rich in prebiotic fiber. 

Prebiotic fiber can be found in many delicious fruits and vegetables. It feeds the beneficial bacteria in your gut and there is evidence that a fiber-rich diet helps to keep stress at bay.

For an extra mood boost, try these handy tips from GUTXY:

1. Add magnesium
   A magnesium-deficient diet was observed to cause higher levels of depression in people with poor microbiome⁸.
2. Avoid highly processed foods
   All those snacks, cakes and biscuits can reduce the number of healthy bacteria in your gut.
3. Exercise
   A sedentary lifestyle has a negative impact both on your mood and gut microbiome.
