Dried Bifidobacterium Animalis Fermentation Product

Suppliers grow a selected bacterial strain in nutrient broth, then harvest and dry the culture. The powder is produced as an additive for food; it is not a leftover from making another food.^5,7

1. 01 // Source Selected culture Production begins with an identified B. animalis strain and a prepared nutrient medium.
2. 02 // Process Grown and harvested Fermentation multiplies the bacteria, which are then separated from the broth.
3. 03 // Process Protected and dried One documented process adds maltodextrin before freeze drying to protect the harvested cells.
4. 04 // Output Dried powder The powder may be mixed with a carrier and applied to kibble after drying.

1. 01

   Adds a cultured microbe

   Manufacturers include it for a proposed gut effect. Studies test identified strains, while the ingredient name alone does not identify the strain or its activity in the finished food.^1,2,6

2. 02

   Takes little recipe space

   A patent describes coating dried kibble with a concentrated AHC7 preparation. That approach adds the culture after the hot processing step and uses little material.⁷

3. 03

   Supports a live culture claim

   The name lets a maker identify the culture in the ingredient list. A separate viable count guarantee gives owners a way to check a live microbe claim.⁶

How much One patented coated kibble used about 0.02% AHC7 preparation; that example does not define a usual amount.⁷

1. Brands say

   It shortens an episode of diarrhea

   Outruns the evidence

   Evidence

   1. Strong
   2. Some
   3. Thin
   4. None

   In a company affiliated trial of 31 dogs with acute diarrhea, live AHC7 shortened average recovery from 6.6 to 3.9 days. A bag naming only the species does not promise that strain or the tested dose.¹

2. Brands say

   It improves the gut microbiome

   Outruns the evidence

   Evidence

   1. Strong
   2. Some
   3. Thin
   4. None

   A placebo controlled trial in 36 healthy dogs found shifts in some bacterial groups and more fecal propionate after 90 days with live or heat treated CECT 8145. Diversity stayed unchanged, and better health was not demonstrated.²

3. Brands say

   It boosts a dog's immune defenses

   Outruns the evidence

   Evidence

   1. Strong
   2. Some
   3. Thin
   4. None

   A 42 day trial in 24 healthy beagles measured higher blood antibody levels after a heat inactivated product. It did not test resistance to illness or show that an unnamed dried culture gives dogs stronger protection.³

4. Brands say

   It firms a healthy dog's stool

   Outruns the evidence

   Evidence

   1. Strong
   2. Some
   3. Thin
   4. None

   Stool scores did not differ in the 90 day live culture trial. A separate heat inactivated product changed scores at day 21, but the difference was gone at day 42. Healthy-dog stool firming is unproven.^2,3

5. Brands say

   It helps dogs lose weight

   Outruns the evidence

   Evidence

   1. Strong
   2. Some
   3. Thin
   4. None

   Body weight did not differ between groups in the 90 day trial of 36 dogs, despite changes in some gut measurements. Those measurements do not show that this ingredient reduces weight.²
