Psychobiotics refers to live bacteria that may provide mental health benefits by affecting the microbiota in the host's gut-brain axis. Common psychobiotics used in research include Bifidobacterium and Lactobacillus families of gram-positive bacteria, which are less likely to cause an immunological response. Specific psychobiotics like Lactobacillus rhamnosus have been shown to lower anxiety and reduce obsessive-compulsive disorder. Probiotic foods high in beneficial bacteria include yogurt, kimchi, kefir and sauerkraut. Research suggests psychobiotics may reduce stress hormones, stimulate the vagus nerve, and increase neurotrophic factors to help treat anxiety disorders.

2. PSYCHOBIOTICS
• Psychobiotics is a term used in preliminary research to refer to live
bacteria that, when ingested in appropriate amounts, might confer
a mental health benefit by affecting microbiota of the host organism.
• Whether bacteria might play a role in the gut-brain axis is under research.

3. TYPES
• In experimental probiotic psychobiotics, the bacteria most commonly used
are gram-positive bacteria, such as Bifidobacterium and Lactobacillus families.
• These do not contain lipopolysaccharide chains, reducing the likelihood of
an immunological response.
• Prebiotics are substances, such as fructans and oligosaccharides, that induce
the growth or activity of beneficial microorganisms, such as bacteria on
being fermented in the gut.
• Multiple bacterial species contained in a single probiotic broth is known as a
polybiotic.[5]

(Probiotic/prebiotic)
Benefits
Lactobacillus rhamnosus Lower anxiety, reduce obsessive – compulsive disorder (OCD)
Bifidobacterium longum Treat depression, reduce anxiety, reduce cortisol
Lactobacillus plantarum Reduce anxiety, increasing dopamine and serotonin, lowering stress
hormone levels and reducing inflammation
Lactobacillus helveticus Reduce cortisol, reduce paranoid and obsessive-compulsive thoughts,
reduce stress hormone level and increased serotonin level
Lactobacillus reuteri Relive from social anxietyand autism
Lactobacillus casei Treat fatigue, digestive problems and anxiety
Lactobacillus fermentum Treat anxiety
Bifidobacterium breve Reduce anxiety
Galacto oligosaccharides Decreased the secretion of cortisol, reduces anxiety.

7. FACTS BEHIND THIS…
• A person can get rid of his anxiety by stimulating the vagus nerve,
reducing stress hormone levels.
• Brain developed neurotrophic factor, crowding out pathogenic bacteria and
increasing nutrient production and absorption.
• There are nine best psychobiotics that have been shown in human and
animal studies to decrease stress and help to treat anxiety disorders.
• They are truly the best probiotics for anxiety.
