Probiotics & Postbiotics

Microbial ingredient qualification starts with the exact strain, not a general species name. This category lists freeze-dried preparations with individual strain designations. Two products in the same genus can be different purchasing choices; a generic probiotic label does not establish identity, viable count, application suitability or the documentation needed by your quality team.
When you contact us, include the full strain designation, intended product format, target viable count basis, storage conditions and destination market. Ask for the current specification and which identity, count and microbiological documents are available for the particular preparation. Count units, test timing and handling conditions should be compared on the same basis. We will not assume that evidence for one listed strain applies to another strain or to a finished product claim.
Compare specific products:

Bifidobacterium breve HC2953 Freeze-Dried Powder and Bifidobacterium bifidum HC2273 Freeze-Dried Powder are different Bifidobacterium strain products that need separate review.
Bifidobacterium animalis subsp. lactis HSLA-009 Freeze-Dried Powder and Lactobacillus acidophilus HC1356 Freeze-Dried Powder show why genus, species and strain codes should all appear in an RFQ.
Lacticaseibacillus rhamnosus HC1509 Freeze-Dried Powder and Lactiplantibacillus plantarum HC1775 Freeze-Dried Powder are distinct lactic-acid-bacteria listings to compare by designation.
Bacillus subtilis D165 Freeze-Dried Powder and Saccharomyces D571 Freeze-Dried Powder broaden the comparison to a Bacillus and a yeast preparation.

Before discussing a sample or quotation, send your required strain name and the acceptance criteria used by your quality team. If your project needs a particular count at a defined point in shelf life, describe that requirement explicitly; the product name alone cannot answer it. We can then check the matching listed preparation and available documents for review. Send your target strain and qualification checklist.
