The gut microbiome is the trillions of microbes in your digestive tract that shape digestion, immunity, mood and metabolism.

Lab tests deliver a precise snapshot occasionally; passive monitoring delivers a continuous trend. Antibiotics, ultra-processed food and chronic stress are the fastest ways to erode a healthy microbial community.

Complement, not replacement

Smart-toilet data on stool form and consistency on the Bristol scale and colour and transit-related cues is best used to decide when a lab test is worth booking — and to give it context afterwards.

Friction is the differentiator

Microbial diversity is one of the strongest correlates of long-term gut resilience, and it shifts with every meal, medication and night of sleep. The test you actually take every day beats the perfect test you take once a year.
