Lactobacillus reuteri: The Gut Microbe Linked to Love Hormone, Better Sleep, and More - Henlus - 07-10-2026

Want to hear something wild? There's a specific microbe called Lactobacillus reuteri that's missing in 95-96% of the population, and its absence could be linked to a host of modern health issues.

This microbe, when restored, has been shown in studies to increase oxytocin, the "love hormone," which can improve social behavior and even impact physical attributes like skin thickness and muscle mass.

The original discoverer found this microbe everywhere in the 1960s, even in breast milk, but over time, it's virtually disappeared from the human microbiome, likely due to antibiotics and modern living. It makes you wonder how much of our current health crises, from gut issues to social isolation, could be tied to losing these fundamental microbes.

It's truly astounding how replacing something our bodies were meant to have can have such widespread beneficial effects, from better sleep to improved body composition and even potentially reversing chronic conditions.

This is very interesting. I never knew one tiny microbe could affect so many things.

I wonder if eating fermented foods can help bring this microbe back.
Modern life has changed our bodies in many ways. Maybe this is one of them.

@Ekene. Yes fermented foods can help. But without lab tests you won't know if they contain it.

If this is true, then gut health is even more important than many people think.

It is amazing how our gut bacteria can affect our brain and emotions.
Antibiotics save lives, but we should also think about how they affect our gut microbes

Better sleep, better mood, and stronger muscles from one microbe? That sounds worth studying.
The human body is more connected than we realize. The gut and brain work together.

This reminds me that good health is not only about vitamins and exercise
