What counts as a biomarker

Digestive health underpins energy, immunity and comfort, yet it's usually tracked only from memory. In practice, a biomarker is useful when it is measurable, repeatable and connected to action.

Smart-toilet markers

LUXOSMT focuses on stool form and frequency, regularity and transit cues and response to diet and stress, because those signals can be collected passively and compared over time.

  • Stool form and frequency
  • Regularity and transit cues
  • Response to diet and stress
Useful digestive health data is not a single answer — it is a trusted trend, explained clearly enough to act on.

Frequency is the breakthrough

Bloating, irregularity and food-related discomfort are common but non-specific, so trends matter more than single days. hydration, regularity and recovery context around training load requires repeated measurement, not a single lab snapshot.

Making biomarkers understandable

Explainable AI should show which marker moved, over what time window, and why the change may matter.

Using the output well

The best result is fewer blind spots between sessions and competitions: clear context, not a diagnosis or a panic-inducing score.
