Brain fog, mood swings, and memory lapses are among the most common complaints during the menopause transition and most of the conversation stops at hormones. The gut rarely comes up. Our founder spent more than two decades building diagnostic tools for life sciences, and has spent the last several years applying that background to a question most people never think to ask: what does your gut have to do with your brain?
What Is the Gut-Brain Axis?
The gut and brain are connected in two key ways. First, there is a direct anatomical link; the nerves running through the digestive system connect directly to the central nervous system. Second, there is a chemical connection, which may matter even more. Gut microbes produce, or help produce, neurotransmitters. When well-nourished, they also generate short-chain fatty acids compounds associated with reduced inflammation throughout the body. That matters because inflammation directly affects brain function, cognition, and mood.
This is not a new discovery. Researchers have known for decades that gut bacteria influence mood and anxiety. Early experiments found that introducing a single bacterial strain to lab animals produced measurable changes in anxiety behavior. The relationship runs in both directions: emotional state affects digestion, and what is happening in the gut affects how clearly a person thinks.
How Menopause Changes the Gut Microbiome
Estrogen shapes the gut microbiome, so when levels decline during perimenopause, the effects extend well beyond hormones. Women spend roughly a third of their lives in menopause, yet only a small fraction of published microbiome research focuses specifically on this period. This is a significant gap given how much is at stake.
What is understood so far: as the ovaries reduce estrogen production, the body continues generating small amounts through adipose tissue, which appears to ease some symptoms. Certain gut microbes also help recycle estrogen that would otherwise be eliminated. A function referred to as the estrobolome. The downstream effects are not all beneficial. Menopause-related shifts in the gut have been linked to cardiovascular risk, diabetes risk, and changes in gut lining integrity. Whether the microbiome can be used as a tool to manage menopause symptoms remains an open question, though early findings are encouraging.

A Simple Way to Track Gut Health at Home
The Coprata Microbiome Activity Tracker (MAT) makes gut tracking simple. Instead of analyzing your entire microbiome, it measures a single, well-researched indicator: fecal pH. This acidity level correlates with the production of short-chain fatty acids, which help reduce inflammation and support immune function. Testing used to require a lab, but the MAT provides rapid, at-home results on a 1-to-10 scale. Because healthy ranges vary, the tool uses a few basic profile details to ensure your score is accurate.
Because gut health doesn't change overnight, the MAT comes in a pack of three. This allows you to establish a baseline, make a targeted change) like adjusting your diet (and retest two to four weeks later to see what actually works. Note that the MAT is a wellness tool, not a diagnostic test; if you are experiencing medical symptoms, consult a doctor.ofTurn this into a LinkedIn post
Food for Thought: Supporting Your Gut-Brain Health After 40
A common misconception is that eating the same healthy meal every day is sufficient. When it comes to feeding a diverse microbial ecosystem, variety matters more than repetition. Berries are a strong addition this time of year they carry a high fiber-to-sugar ratio along with polyphenols, the compounds that give them their color and support brain health. Beans are another high-fiber staple worth rotating through in as many varieties as possible.
Looking Ahead
Our team is also developing a smart toilet capable of measuring gut health biomarkers automatically no specimen handling required. Working demonstrations already exist, and it will follow the MAT to market as the next step in passive gut health monitoring.
If you want to know where your gut health stands today, the Gut Reset Program includes three MAT kits for $89.99. Enough to establish a baseline, make a change, and measure whether it made a difference.
