Why Do Some Manufacturers Use Coded Strains in Their Probiotics While Others Don't?

Why Do Some Manufacturers Use Coded Strains in Their Probiotics While Others Don't?
Probiotics are a booming category these days. But not all probiotics are created equal. There are many elements that make one product differ from the next, but one important element is the strains used.

Have you ever noticed that some companies list their probiotics like this: Bifidobacterium bifidum A058 while others list it like this: Bifidobacterium bifidum? What’s the difference?

Coded Strains 101

A probiotic is a type of bacteria that has been identified as a genus (e.g lactobacilli or bifidobacteria), species (e.g. acidophilus) and strain (e.g. A058).

When a company uses strain codes, it means that they can tract the exact origin of the strains used in their probiotic.

Although it costs more money to do this, it creates a better probiotic. And you can rest assured that the strain being used is of known origin!

That’s why we use coded strains in advanced gut health probiotic. The strains that we use are 100% human strains, are non-GMO, and do not come from animals.

Do probiotics that use human strains have an 'H' in their code?

Not necessarily. Some manufacturers use acronyms for the strain names, while others prefer to indicate that their strains are human by using an 'H.' But an H in the code has no bearing on whether the strain is actually human. The only way to know whether a strain is of human origin is if the manufacturer tells you that it is!

advanced gut health probiotic was crafted with 15 hearty and healthy human strains. Although we do not use strain codes with an H for Human, you can rest assured that the strains that we use are indeed human strains. Here's a look at the strains found in advanced gut health probiotic:


  • Bifidobacterium bifidum A058

  • Bifidobacterium breve A055

  • Bifidobacterium infantis A041

  • Bifidobacterium lactis A026
