For the Nervous System

Our microbiome-gut-brain axis is related to numerous physical, mental, and neurological conditions and disorders. Certain bacteria within our gut microbiome can yield specific benefits, both directly and indirectly, to our nervous system. They are referred to as psychobiotics. 


Research into the benefits and mechanisms of pyschobiotics is quickly progressing, and this group of probiotics is a natural, safe option for those for maintaining neurological and mental wellbeing.


For the Mind & Body

Probiotics have traditionally been used to aid digestion, immunity, and metabolism. Psychobiotics such as L. plantarum PS128 have expanded these indications to include nervous function and mental health.


Scientific evidence has shown taking L. plantarum PS128 can benefit mood, behavioral development, and neuromuscular function. It works through our gut to modulate levels of neurotransmitters in our brain and hormones throughout our body. These include dopamine, serotonin, BDNF, and cortisol.


Clinical trials have shown positive outcomes for symptoms of stress, anxiety, and insomnia, as well as for those with autism and Parkinson's diseasePS128 has also been shown to improve physical recovery and athletic performance, reduce inflammation, and promote healthy immune and gastrointestinal function.


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