Antibiotics, chronic stress, and ultra-processed food strip out the beneficial bacteria humans evolved with. Most probiotics try to replace them with strains borrowed from dairy or soil — passengers, not residents.
Progurt uses Human Probiotic Isolates™, the species your body hosted from birth, delivered at clinical potency in a sequence designed to actually stick.
Twelve peer-reviewed sources. Three decades of clinical practice. Four findings that shape every Progurt protocol — with the citations to read for yourself.
Years.How long human-origin strains persist
01
Human-origin strains engraft
Your bacteria. Not borrowed from dairy, soil, or fermented food.
Gut-native species colonise and persist for years. Transient strains from yoghurt or soil pass through within days. Progurt uses human-origin isolates — the same species your body hosted from birth.
Your gut holds 100 billion bacteria per gram. Most supplements deliver 10–50 billion CFU — a rounding error. The clinical trials that showed real outcomes used 900 billion to 1.8 trillion. That's our range.
70%Of strains engraft only when terrain is prepared
03
Terrain preparation matters
You can't plant a garden in concrete.
Mineral balance, pH, and mucosal integrity determine whether bacteria colonise. Prepare the terrain first and probiotic strains take hold; skip it, and most pass straight through. It's why the M phase comes before the E phase.
Skipping preparation leads to 5.5× higher recurrence in clinical microbiome restoration. The MEND™ Method follows the same sequence used in clinical transplant protocols — prepare, seed, feed, protect.
