Buyer Decision Guide
Probiotics are specified by strain, potency at delivery and enumeration method. Confirm the strain designation, the CFU basis (per gram or per dose) and the overage required to hold potency through your shelf life and packing format.
- Confirm the strain designation, not only the species
- Check the CFU basis and enumeration method
- Review water activity and viability data
- Confirm cold-chain and packing requirements
How This Grade Differs
D295 is a specific strain and is not interchangeable with other strains of the same species. Potency, water activity and enumeration results differ by strain and by production lot, so qualification must be strain-based.
