How the
test was run.

Each batch of CoreBiotic is sent to an independent, ISO/IEC 17025–accredited third-party laboratory for full Certificate-of-Analysis testing. The lab has no commercial relationship with VitalCore — its sole role is independent verification. The COA covers identity, potency, and contaminants per USP compendial methods.

Method
What it verifies
16S rRNA sequencing
strain identity confirmation
Strain-specific PCR
quantitative viability per strain
Plate-count enumeration
Lactobacillus MRS agar, Bifidobacterium reinforced clostridial medium
ICP-MS
heavy metals (Pb, As, Cd, Hg) per USP <2232>
USP <2021> / <2022>
total aerobic microbial count, yeast & mold, E. coli, Salmonella, S. aureus

Methods chosen per USP compendial standards. Full raw data is bookmarked in the PDF Certificate of Analysis linked below.

Strain identity
is what we say it is.

Strain identity matters. Mislabeled organisms are one of the most common issues in the supplement industry — a product marketed as a clinically-studied strain could contain a less-studied related organism without the label showing anything different. 16S rRNA sequencing eliminates that gap.

16S rRNA strain identity match

Plate purity (target organism fraction)
≥ 98.0%
99.4%

Identity verification is what separates a probiotic brand that posts a COA from one that posts a marketing sheet.

50B CFU, strain
by strain.

A "50 billion CFU" label is only meaningful if every strain contributes what it should. Most multi-strain probiotics enumerate only the total — you can't verify that strain A wasn't crowded out by strain B. We test each one independently. Real numbers, real strains, real results.

Nothing else
in the bottle.

Heavy metals, microbials, and pathogens are why third-party testing is non-negotiable. These analytes are commonly found in low-quality raw ingredient streams. Every batch is tested for the full USP <2232> panel plus microbial limits per USP <2021> / <2022>.
