Quality and Testing
No additives, binders, or fillers.
Every BioMirco formula is manufactured at a Good Manufacturing Practice (GMP) certified facility in the United Kingdom, and verified by an independent third-party laboratory before release. The point of this page is to tell you exactly what we test for, where we make it, and what we leave out.
Every batch. Every certificate.
What we test for, on every production batch:
- Heavy metals (Lead, Cadmium, Mercury, Arsenic)
- Microbiological safety (E. coli, Listeria, Coliforms)
- Gluten (not detected)
- Ingredient potency vs label claim
- Pesticide residue screening
- Allergen contamination
Every certificate is available on request. We publish recent batch test summaries publicly. Request a Certificate of Analysis →
UK GMP-certified facility.
GMP is the gold-standard certification for supplement manufacturing. It covers facility hygiene, equipment calibration, ingredient traceability, batch records, and finished-product testing.
We do not use overseas contract manufacturers, white-label suppliers, or co-packing arrangements that obscure ingredient sourcing.
Six promises we keep.
Active forms always
5-MTHF folate, methyl + adeno B12, natural ubiquinone CoQ10. No synthetic shortcuts.
Research-backed doses
Doses informed by published research, not minimum-deficiency floors.
No magnesium stearate
The cheap manufacturing lubricant most supplements use. We do not.
No artificial anything
No artificial colours, flavours, or sweeteners. Across the entire range.
Vegan capsule shells
Plant-based HPMC delayed-release. No gelatin in any product.
Independent testing
Every batch verified by an accredited third-party lab. Not just our own QC.
What is NOT in the bottle.
This is just as important as what we put in.
- Synthetic folic acid. We use 5-MTHF only.
- Cyanocobalamin B12. We use methylcobalamin and adenosylcobalamin only.
- Magnesium stearate. A manufacturing lubricant. Not in BioMirco.
- Titanium dioxide. A common capsule colourant. Not in BioMirco.
- Unnecessary bulking agents, anti-caking flow aids, or carriers.
- Artificial colours, flavours, or sweeteners.
- Gluten, dairy, soy, GMOs.
