Yes. Your microbiome produces key compounds that influence multiple systems beyond digestion. For example, microbes generate short-chain fatty acids that regulate energy metabolism and keep inflammation under control.
The gut also produces around 90% of your body’s serotonin, a neurotransmitter that affects mood, appetite, and sleep. Certain microbes also produce GABA, which helps calm the nervous system.
This connection is called the gut-brain axis — a two-way communication channel linking your digestive system and your brain. It explains why stress can cause stomach issues and why gut balance can affect mental clarity.
Energy levels are also tied to microbial health. When your gut microbes efficiently break down food, they release nutrients and energy more steadily, preventing the spikes and crashes that many people feel.
An imbalanced microbiome can lead to brain fog, fatigue, anxiety, or digestive problems. This happens when harmful bacteria crowd out beneficial strains, creating inflammation and nutrient gaps.
Supporting your gut with probiotics like B. adolescentis and targeted prebiotics can strengthen both digestion and mood, creating a more balanced body and mind.
