ReuteriBiotic™

Lactobacillus reuteri LRDR™ Probiotic

Lactobacillus reuteri

 

ReuteriBiotic is a source of the all-important microbe, Lactobacillus reuteri, a bacterial species that provides a long list of health benefits.

 

Lactobacillus reuteri is ubiquitous among mammals such as squirrels, raccoons, deer, and other species unexposed to antibiotics. Likewise, hunter-gatherer humans, also unexposed to antibiotics and other microbiome disruptive factors, all have L. reuteri. It’s therefore modern people who are the exception with nearly all of us having lost this important microbe due to repeated courses of antibiotics and other factors.

 

Dr. Gerhard Reuter, a German microbiologist, discovered L. reuteri (as it was subsequently named) in 1962, isolated from the breastmilk of a breastfeeding mother. Over his 40-year academic career, Dr. Reuter found it increasingly difficult to find this microbe in human secretions. More recent analyses have confirmed Dr. Reuter’s observations: L. reuteri has nearly disappeared from the human microbiome.

Revolutionary Science Discovered by Dr. William Davis

 
 
Hi, I’m Dr. William Davis, a cardiologist, author, and passionate advocate of the power of the gut microbiome. My deep research into the science has reinforced how gut health certainly starts from within.

I advocate the restoration of genuine health, by starting with the foundation, addressing deficiencies, and supporting what our bodies used to produce.
 
ReuteriBiotic™ is a supplement that I personally formulated. With the benefits of our LRDR L. Reuteri super microbe, it’s combined with FOS (fructooligosaccharides) to feed the microbes. ReuteriBiotic™ provides a full 20 billion CFU of L. reuteri in each tiny capsule. ReuteriBiotic™ can be taken in addition to adiponexin™.

You can use a single ReuteriBiotic™ capsule to make my authentic Lactobacillus reuteri cultured dairy “yogurt” superfood. My extended fermentation process results in high-count of L. reuteri gut-friendly microbes, and tastes great, too.

Skin wound healing (as a surrogate for youthfulness) is accelerated by L reuteri, an effect mediate by oxytocin. Dermal collagen increased substantially.
