Every ingredient we’ll consider, in one place.
The full shelf NB1 formulates from: 125+ studied strains, fibres, vitamins, minerals and active compounds. Yours draws on only the ones your reading calls for, the rest stay on the shelf.
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.




The full shelf, every component.
Filter by family or search by name. This is the complete list we formulate from, not a sample.
How the library becomes your formula.
Shotgun sequencing reads what your microbiome is and what it’s set up to do, not just which bacteria are present.
Only the components your reading calls for are drawn from the library, each at the dose your biology supports. Typically 15 to 25.
Your protocol is produced from that shortlist, then rebuilt each cycle as your reading moves.
