for nervous system health

Probiotics that provide benefits to the nervous system are called psychobiotics. Lactobacillus 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

When many people hear "probiotics," they think of something that can simply help improve digestion. Yet scientific research over the past decade or so has greatly expanded our understanding of these gut bacteria and their potential role in our immune system, metabolism, and more. "Next-generation probiotics" (NGPs) are novel strains that are being discovered as benefitting specific functions or even diseases. Some NPGs directly influence the gut-brain axis, which connects our gut to our nervous system. The bacteria living in our intestines are related to many mental and neurological conditions, and those microbes that can benefit our nervous system are referred to as psychobiotics. 


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


PS128 for the
Mind & Body

As a psychobiotic, PS128 has been tested in clinical studies, showing benefits to mood, neurodevelopment, neurodegeneration, and even athletic performance. While its exact mechanism of action is still not fully understood, it works through the gut-brain axis to modulate levels of neurotransmitters (most notably dopamine) and other molecules in our brain and throughout our body, including serotonin, cortisol, and BDNF. 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.
