The most documented digestive-health strain in our library — gastric acid resistant, clinically studied for bowel regularity and immune support, 300 billion CFU/g.
TB-01 is Tingbiotech's flagship bifidobacterium strain, isolated from the gut of healthy Chinese infants and characterised by whole-genome sequencing. It survives simulated gastric juice at pH 2.0 with over 80% viability and is supported by human clinical studies for bowel regularity and upper-respiratory immune defence.
Key Features
Strain-level identity confirmed by WGS + qPCR per batch
> 80% viability after 2h at pH 2.0 gastric simulation
300 billion CFU/g fermentation concentration
Safety: no transferable antibiotic resistance genes (whole-genome safety assessment)
