The Importance of Butyrate in Gut Health

The human gut microbiome is an essential and complex ecosystem that is crucial to our overall health and well-being. Recent research has shed light on the critical role of butyrate, a short-chain fatty acid produced by gut bacteria, in promoting gut health. Kiran Krishnan, a research microbiologist, has been at the forefront of this research and has significantly contributed to our understanding of the importance of butyrate.

What is Butyrate?

Butyrate is a short-chain fatty acid produced by certain gut bacteria, specifically those that ferment dietary fibers. Butyrate is an essential source of energy for the cells that line the colon and has been shown to have anti-inflammatory properties and promote gut barrier function.

Butyrate and Gut Health

The importance of butyrate in promoting gut health has been a significant focus of current research. Studies have shown that butyrate helps to maintain the integrity of the gut lining, preventing the leakage of harmful toxins and pathogens into the bloodstream. Butyrate also regulates the immune system, promotes the growth of beneficial gut bacteria, and reduces inflammation in the gut.

Kiran Krishnan is a research microbiologist who dedicated his career to studying the human gut microbiome and its impact on human health. He is the Chief Scientific Officer at Microbiome Labs, who has conducted clinical studies on the effects of probiotics and prebiotics. One study by Krishnan and his team examined the effects of a butyrate-producing probiotic on gut health in healthy volunteers. The study found that the spore-based probiotic increased butyrate levels in the gut, leading to improved gut barrier function and reduced inflammation.

Another study looked at the effects of butyrate on inflammatory bowel disease (IBD), a group of chronic inflammatory conditions that affect the gut. The study found that butyrate had anti-inflammatory effects and helped to reduce gut inflammation in patients with IBD.

Butyrate and Other Health Benefits

In addition to promoting gut health, butyrate has also been shown to have other health benefits. Studies have found that butyrate may help to reduce the risk of colon cancer, improve insulin sensitivity, and even improve brain function.

How to Increase Butyrate Levels

There are several ways to increase butyrate levels in the gut. One of the most effective ways is to consume a fibre-rich diet, as this provides the substrate for butyrate-producing bacteria to ferment. Fermented foods, such as sauerkraut and kefir, are good butyrate-producing bacteria sources.

Supplementation with butyrate-producing probiotics is another option. Krishnan’s research has shown that spore-based strains of probiotics are effective at producing butyrate and can help to increase butyrate levels in the gut.


Recent research has shed light on the critical role of butyrate in promoting gut health by maintaining gut barrier function, regulating the immune system, and reducing inflammation.

Moreover, spore-based probiotics have emerged as a valuable tool for promoting gut health and increasing butyrate levels. Spore-based probiotics are unique in their capacity to target harmful bacteria in the gut, functioning as the police of the gut. In addition, they have been found to increase bifidum, acromencia, and other key components of gut health, optimising the host’s well-being.

Our clinic offers highly science-reviewed spore-based probiotics with 99.99% survivability through the digestive tract. By incorporating a diet rich in fibre and supplementing with butyrate-producing and spore-based probiotics, individuals can take adequate steps to support their gut health and overall well-being.
