Bifidobacterium infantis

Optimal result: 10 – 100 Relative Abundance

Bifidobacterium infantis has been shown to strengthen the gut barrier, and increase butyrate production in certain contexts

Currently, the most effective way to increase Bifidobacterium infantis levels is through the use of probiotics

Bifidobacterium infantis is a highly specialized microbe ("beneficial bacteria") that resides in the gut microbiome.

Unlike most other bacteria in the gut microbiome, Bifidobacterium infantis (also known as "b infantis") is an inherited microbe, often being passed down from mother to child during child birth. 

Once it takes up residence in the gut microbiome, Bifidobacterium infantis flourishes and helps to cultivate an environment where other beneficial bacteria can grow. 

Bifidobacterium infantis is a lactic-acid-producing gut bacteria that provides many benefits to newborn infants as well as adults. 

B. infantis is a bacterial species belonging to the Bifidobacteria genus. B. infantis is commonly seen in an infant’s digestive tract, particularly those who are breast fed. Unlike some other Bifidobacteria species, B. infantis does not tolerate oxygen very well, therefore B. infantis takes up its main residence in the colon.

B. infantis is a beneficial microbe and can exert many positive effects supporting human health, thus making it of particular interest in the probiotic industry.

"Watching my numbers move over the years — instead of forgetting last time's results — completely changed how I manage my health."

"Living across several countries made keeping my lab results organized a real challenge. Healthmatters brought my results from the USA, Spain, and Germany together — 20 years of history, with long-term trends instead of scattered reports."

"Standard lab ranges are too wide for how I practice — 'normal' isn't optimal. I set my own bands, so a client sees yellow before a marker goes officially out of range. That's the conversation I want to be having."
