• Most infants born in the U.S. lack B. infantis
  • B. infantis is needed to maximize the health benefits of breast milk (during early development)
  • B. infantis is the only bacteria able to use all breast milk HMOs
  • The M-63 strain of B. infantis has been clinically shown to colonize the infant gut
  • Patent pending bottle design with MCT oil for easy application
Missing in Action

The human microbiome is an incredibly important part of overall wellbeing. An infant microbiome’s development begins at birth. However, research has shown that the infant microbiome has changed in the last few decades. B. infantis levels have decreased due to the increased frequency of caesarian sections, antibiotics, and formula. The change in the microbiome, specifically the loss of B. infantis, is thought to have a profound influence on allergies, obesity, and other problems.

The Proven Probiotic

Jarro-Dophilus® Infant Drops are formulated to with B. infantis M-63, clinically shown to have the highest capacity for colonization when compared to other bifidobacteria. The probiotic is suspended in MCT oil (medium-chain triglycerides), a fat naturally found in breast milk. It is shelf stable and designed for easy application for both formula-fed and breastfed infants. It has the unique ability to use all the complex sugars found in breast milk making it incredibly important during the first six months.

The Probiotic Advantage

What is a Probiotic?

A probiotic is a live microorganism, which, when administered in adequate amounts, confer a health benefit on the host (WHO / FAO). Bacteria and yeast are the most common type of probiotics on the market.

Strains Matter™

Strain designation is incredibly important, it allows you to identify the specific probiotic in a product, how the probiotic behaves, and how concentrated it should be. A strain identifier is a unique letter and number code that follows the genus and species. Typically, looking up a strain in Pubmed or a general search engine will bring up all the studies associated with it.

Avoid probiotics that are not strain identified; their effectiveness cannot be assured. Think of it this way, asking for Bifidobacterium infantis is asking for a health professional (doctor, nurse, nutritionist, etc.), while Bifidobacteria infantis M-63 is asking for a pediatrician.

What role do HMOs play in the microbiome?

Human milk is rich in unique, complex sugars (over 200) called human milk oligosaccharides (HMOs). They are the third largest component after lactose and fat, yet are indigestible. Their primary function is to promote the growth of select, beneficial bacteria, mainly Bifidobacteria.

Bifidobacteria infantis is unique, as the only bacterium with the ability to utilize all HMOs. It will outcompete any other bacterium living in the gut, limiting their growth. Its presence results in higher acetic acid concentrations, which lowers pH, and significantly more Bifidobacteria and fewer undesirable bacteria. Increased levels of B. infantis has been associated with:

  • lower levels of non-beneficial bacteria
  • improved growth
  • gut maturation
  • vaccine responsiveness
  • modulation of immune development and function
