Your gut isn't broken.
It's been depleted.

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.

The science

Published. Cited.
Replicated.

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.

1TCFU per sachet vs. 10–50B typical
02

One trillion CFU per sachet

A dose that matches the scale of your microbiome.

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.

Sood et al., Clin Gastroenterol Hepatol, 2009

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.

Zmora et al., Cell, 2018

5.5×Lower recurrence when sequenced
04

Phased protocol holds

Four phases. In order. For a reason.

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.
