When the Microbiome Shrinks – Organic Acids, Neurotransmitters and Depression.
October 5, 2026
Overview
This exciting and in-depth webinar will illustrate how the microbiome is considered a virtual organ that has the ability to shrink or swell dramatically in size. Dr. Rostenberg will highlight how individuals suffering with a depressed, shrunken microbiome often present with symptoms of low catecholamines, depression and chronic fatigue. He will share his logical, repeatable and systematic process for testing the microbiome to identify patients at risk from this powerful gut-brain relationship. Additionally, he will share his experience creating specific diet and nutrient protocols to quickly restore microbial balance and alleviate symptoms.
Objectives
Learning Objectives
- The microbiome is a “virtual” organ that can shrink in size, with powerful consequences to host brain, endocrine and metabolic pathways.
- Lack of adequate gut bacteria leads to deficiencies in gut neurotransmitter production.
- Without gut neurotransmitter production, the human nervous system suffers with lower levels of dopamine and monoamines causing mood changes and depression.
- Organic acids offer affordable, reliable testing to identify individuals with a depressed microbiome.
- Learn which fermented foods, probiotics, prebiotics and amino acids are effective at quickly restoring balance to the microbiome and improving neurological health.
