In a newly published study Probi´s proprietary strain Lactiplantibacillus plantarum HEAL9 (HEAL9™) was shown to significantly improve cognitive performance. The result of the study is encouraging ahead of Probi's launch of a new product in the gut-brain area.

The randomized controlled study investigated the effects of the HEAL9™ strain on stress, cognition, sleep and mood in 129 healthy but stressed individuals. The data showed significantly improved learning and working memory after consumption of HEAL9™ for 12 weeks compared to placebo. There were also strong tendencies for improved mood and sleep in the HEAL9™ group. This is the third clinical study in mental health documenting strong results on HEAL9™.

“Mental health and wellness is a field with significant growth potential. This complementary study demonstrates that our strain HEAL9™ has a strong clinically proven effect in the gut-brain area and boosts our confidence ahead of the official launch of our new product at Supply Side West in Las Vegas in October." says Anita Johansen, CEO of Probi.

The study “Intake of Lactiplantibacillus plantarum HEAL9 Improves Cognition in Moderately Stressed Subjects: A Randomized Controlled Study” was recently published in Nutrients (2023) 15 (15), 3466

Is Lactiplantibacillus the same as Lactobacillus?
Lactiplantibacillus plantarum used to be classified under the Lactobacillus genus. But Lactobacillus was split up into 25 different genera in April 2020. Some sources might still list this species as Lactobacillus plantarum rather than its new name, Lactiplantibacillus plantarum.
