Probiotics made in Gonbad-e Kavus, Iran
Pharmaceutical discipline, living science.
We make probiotics with the rigour of a drug manufacturer. Every product carries its strain, its count and its batch, and we stand behind all three.
Live, counted and proven.
Three facts appear on every Aria Darou Qabus product, so anyone can check what they are taking.
- Strain
- Named in full, genus, species and strain code, so it can be looked up in the research.
- Count
- Live cultures stated in CFU and guaranteed to the end of shelf life, not just on the day of manufacture.
- Batch
- A batch number that traces back to the fermentation run and the release record.

A probiotic only works if it arrives alive.
Billions of bacteria have to survive fermentation, drying, packing, shipping and months on a shelf. Our work is making sure the count on the label is still true on the last day of shelf life.
From strain to sealed pack
Five controlled stages, each with its own release criteria.
Strain selection
Characterised strains from verified culture collections, with identity confirmed before use.
Fermentation
Controlled temperature, pH and time, so each culture reaches the same growth phase every run.
Concentration and drying
Cells are harvested and freeze-dried with protectants that keep them alive.
Formulation
Blended to the target count per dose and filled as capsules, sachets or powders.
Release testing
Viable count, identity and purity are tested on every batch before it ships.
