Your bones might receive help from an unexpected source: the trillions of bacteria living in your gut.
An interesting new study published in npj Metabolic Health and Disease found that certain gut bacteria can actually help maintain bone density and protect against age-related bone loss and osteoporosis.
Because there are so many of them, gut bacteria influence many aspects of human health.
But their relationship with osteoporosis and bone strength is still mostly unexplored.
The research team decided to investigate this connection by studying 684 adults.
First, they used advanced CT scans to measure the bone density in each participant’s lower spine.
Then, they analyzed stool samples to identify all the different types of bacteria living in each person’s gut using a technique called shotgun metagenomic sequencing.
This method doesn’t just identify which bacteria are present, but also what they’re doing.
The researchers also collected detailed information about each participant’s age, diet, and lifestyle habits to understand how these factors might influence the relationship between gut bacteria and bone health.
Here are the study’s key findings:
-
1. People with higher bone density had more of certain gut bacteria — especially from the Lachnospiraceae family, including species like Lachnospira eligens, Blautia wexlerae, and Roseburia hominis.
2. These bacteria are known to produce butyrate, a compound that reduces inflammation and helps balance bone breakdown and formation.
3. They also found more microbial activity in the L-arginine biosynthesis pathway, which produces an amino acid linked to improved bone health.
4. Participants with a Bacteroides-dominant microbiome (called enterotype B) experienced faster bone loss with age compared to those with a Prevotella-dominant microbiome (enterotype P).
5. These patterns held true across both men and women and were confirmed in a second group of participants.
If it’s true that butyrate- and L-arginine–producing species are strongly linked to better bone density, there’s a very direct way to support them: simply eat plenty of oats, barley, brown rice, legumes, bananas, apples, berries, onions, garlic, leeks, broccoli, kale, and other fiber-rich foods.
Their fiber feeds these beneficial bacteria.
This comes as no surprise to me. I’ve helped thousands of men and women to reverse their Osteoarthritis naturally.
And one of the key elements to achieve this is boosting your gut health with the right food choices.
But gut health is only one piece of the puzzle.
