Four families, one library.

Every component belongs to one of four groups. Together they cover the living layer of the gut, the fibres that feed it, and the micronutrients and actives that support the rest.

How the library becomes your formula.

01
We read your gut

Shotgun sequencing reads what your microbiome is and what it’s set up to do, not just which bacteria are present.

02
We match, and leave out

Only the components your reading calls for are drawn from the library, each at the dose your biology supports. Typically 15 to 25.

03
We build and recalibrate

Your protocol is produced from that shortlist, then rebuilt each cycle as your reading moves.
