A Novel Probiotic Strain with Gut-Brain and Upper Respiratory Benefits

In this webinar, Dr. Rober J. Barry discusses Lactobacillus plantarum DR7, a cow’s milk isolate from Penang, Malaysia, which has shown a reversal of symptoms associated with Alzheimer’s Disease in a fruit fly model, accompanied by distinct changes of gut microbiota profiles. In aging rats, DR7 has shown improved stress and anxiety symptoms, accompanied by improved memory.

The administration of DR7 for 12-weeks in stressed adults has contributed to improve stress and anxiety scores, in addition to memory and cognitive abilities, primarily via enhancement along the serotonin pathway and maintenance of the dopamine pathway.

Gut microbiota analyses of human subjects also showed correlations between changes in neurotransmitter genes and different taxonomic levels of gut microbiota along the serotonin and dopamine pathways. This evidence involving various models, strongly indicated an effect of DR7 along the gut-brain-axis.

The webinar recording lasts for 26 minutes, including a Q & A session.
