Can This Probiotic Fix Your Gut and Hair?

•, By Dr. Joseph Mercola

However, as noted in a 2016 paper,1 gut bacteria also "exert effects beyond the local boundaries of the gastrointestinal tract to include distant tissues and overall health."

For example, the probiotic bacteria Lactobacillus reuteri help upregulate the hormone oxytocin, a chemical messenger that plays important roles in the male and female reproductive systems and influences aspects of human behavior, including sexual arousal, recognition, trust and interpersonal bonding.2

L. reuteri also upregulate systemic immune responses, thereby promoting wound healing, mental health, metabolism and myoskeletal maintenance.3 Some of these effects are achieved through competitive inhibition, which is when beneficial bacteria crowd out harmful ones.

Beneficial bacteria like L. reuteri also serve important signaling functions, and as a whole, your gut microbiome interacts with various systems of your body via immune-endocrine-brain signaling networks.

As such, probiotics "provide novel therapeutic strategies to stimulate powerful homeostatic pathways and genetic programs, stemming from the coevolution of mammals and their microbiome," the 2016 paper4 concludes.

An earlier study, published in 2013,5 found that aged mice fed a commercially-available vanilla-flavored L. reuteri-containing probiotic yogurt experienced skin and fur changes that mimic the "peak health and reproductive fitness characteristic of much younger animals," including a thicker dermis, and thicker, shinier, more lustrous coats.
