a psychobiotic for nervous system balance

Probiotics that provide benefits to the nervous system are called psychobiotics. Lactiplantibacillus plantarum PS128 is one of these uniquely effective strains.

PS128 is a natural, safe way to boost mental and neural health. It works from within the gut to balance levels of dopamine, serotonin, and other molecules.

Psychobiotics for the
Nervous System

Derived from the Greek meaning "for life", "Probiotics" often makes people think of something that can be taken to help improve digestion. Yet scientific research has greatly expanded our understanding of probiotics and their roles in our immune system, metabolism, and more. Over the past decade or so, a "microbiota-gut-brain axis" has been studied. This pathway, stretching from the microbes in our gut all the way up to our brain, sends information both ways. The microbiota inside of us influences how our nervous system functions, even affecting certain symptoms or diseases. Those probiotic strains that potentially benefit mental health are termed psychobiotics.


Further understanding of psychobiotics, their benefits and mechanisms, is quickly progressing. This group of probiotics is a natural, safe way to help many maintain neurological and mental health.


PS128 for the
Mind and Body

PS128 psychobiotic has been shown in clinical studies to benefit mood, neurodevelopment, neurodegeneration, and even athletic performance. While its exact mechanism of action is not well understood, it seems to function through the gut-brain axis to modulate levels of neurotransmitters, hormones, and other molecules in our brain and throughout our body. Levels of dopamine, serotonin, cortisol, and BDNF have all shown to be affected by PS128 supplementation. Research has also demonstrated PS128 can

  • benefit gastrointestinal function,

  • improve immune function, and

  • reduce inflammation.


The strain has been patented in the US, the EU, Japan, South Korea, China, and Taiwan.
