Butyrate levels And hight and duration of puberty adolesents

[Satvik20]

Butyrate is a short-chain fatty acid that is produced by the bacteria in your gut. It's one of the biggest influencers of epigenetic expression, strongly influencing how your height genes are expressed.

Butyrate and your genetic height potential.

In one 2022 study, it was found that children suffering from idiopathic short stature (ISS) had butyrate levels that were on average 54% lower than in children of normal height, a huge statistical difference.

Then in 2025, an even more interesting study emerged. In this study, researchers tested what would happen if growth hormone was given to children with either idiopathic short stature or growth hormone deficiency.

These children that received growth hormone were divided into groups:

• Kids that grew a lot from growth hormone therapy
• Kids that grew a decent amount
• Kids that grew a more average amount

Trying to understand why some children responded extremely well to growth hormone therapy while others only grew a little, researchers started looking at the gut microbiome of these children.

What they found was interesting.

The children who responded the best to growth hormone therapy had significantly higher levels of butyrate in their gut compared to the children that did not respond as well.

Shorter children not only tend to have lower butyrate production on average, but lower butyrate production may also reduce how effectively the body responds to growth hormone.

So how does butyrate actually change how your height growth genes are expressed?

One proposed mechanism is through inhibition of histone deacetylases (HDACs). These are enzymes involved in suppressing gene expression. Butyrate may reduce this suppression and help activate genes associated with:

• Bone growth
• Osteogenesis
• Growth plate activity

Research suggests butyrate may upregulate expression of genes involved in skeletal development.

But that isn't the full story.

Butyrate may not only support height growth by influencing gene expression, it may also play a role in slowing down growth plate closure.

Butyrate and growth plate closure.

Butyrate does not simply upregulate every gene. It may also downregulate certain pathways, including some related to estrogen signaling.

Estrogen is one of the main hormones involved in ossification of the epiphyseal growth plates. This is the process where growth plate cartilage gradually turns into bone. Once the growth plates fully close, height growth largely stops.

Some researchers believe butyrate may help slow this process through its effects on estrogen receptor expression.

There are also interesting observations involving estrogen metabolism:

• Males with aromatase deficiency can experience delayed growth plate closure
• Excess estrogen activity is associated with earlier growth plate fusion
• Children with precocious puberty often experience earlier growth plate closure

Interestingly, lower butyrate levels have also been observed in some children with precocious puberty.

So to summarize:

1. Shorter children tend to have lower butyrate levels on average.
2. Growth hormone therapy response may be influenced by butyrate levels.
3. Butyrate may influence expression of genes related to height growth.
4. Butyrate may also influence growth plate closure pathways.

Increasing butyrate production in the gut may help support overall gut health and healthy development during puberty.

Some foods and compounds associated with increased butyrate production include:

• Royal jelly
• Propolis
• Milk and dairy products
• Certain probiotic strains such as Lactobacillus reuteri
• Sodium butyrate
• High-fiber foods that feed beneficial gut bacteria

That said, genetics still play the largest role in final adult height. Sleep quality, nutrition, exercise, hormone health, and overall health during puberty remain the most important evidence-based factors for reaching your full growth potential.

In conclution Height is all genetics is one of the most untrue and true statements there is. It lacks full nuance and can be misleading because it's not just about the genetics you get from your parents. It's also about how your genes are expressed and that's something you can take control of. You can basically influence how your height growth genes are expressed, and modern research only proves this further.
