Bottom line. Independent meta-analyses agree that microbial 6-phytase improves broiler growth, feed efficiency and bone mineralisation and raises phosphorus retention (about +8.6 points at ~1,000 FTU/kg).

Discussion — grounded in the evidence
- Independent meta-analyses agree that microbial 6-phytase improves broiler growth, feed efficiency and bone mineralisation and raises phosphorus retention (about +8.6 points at ~1,000 FTU/kg).
- EFSA judges the additive efficacious and safe, with authorisation renewed in 2025 and extended to fin fish in 2024.
- The reduced-phosphorus-excretion claim follows directly from the measured rise in phosphorus retention.
- The 'super-dosing'/inositol story is mechanistically supported but largely manufacturer-led, and its extra performance benefit is clearest on phosphorus-deficient diets.
- Independent matched-dose comparisons against rival E. coli phytases are scarce.
Where studies disagree: Super-dosing growth benefits are most reliable on phosphorus-/calcium-deficient diets; in fully adequate diets the extra response is smaller and less consistent.
Gaps: Few head-to-head independent trials of Quantum Blue versus other commercial E. coli 6-phytases at matched FTU. Economic-return claims under commercial conditions rest largely on manufacturer modelling.
Manufacturer’s stated mechanism (their words): Hydrolyses phytate (IP6) stepwise to lower inositol phosphates and myo-inositol, releasing phytate-bound phosphorus, calcium and other cations and removing phytate's anti-nutritional mineral/protein binding.
