Sodium butyrate is a supplement form of butyric acid, a short chain fatty acid your gut naturally produces when breaking down fibre. More people are exploring it for gut health support, but what exactly is it used for?
This guide explains the main uses of sodium butyrate, how it works in your body and why it's become popular in digestive wellness.
Supporting colon health
One of the primary uses of sodium butyrate is to support the cells that line your colon. These cells, known as colonocytes, rely on butyrate as their main source of fuel. When butyrate levels are sufficient, these cells function properly, maintaining the integrity of your gut lining.1
This is particularly important for people whose natural butyrate production may be compromised due to low fibre intake, digestive imbalances or antibiotic use. Supplementing with sodium butyrate helps provide this essential fuel directly to where it's needed.
Maintaining a healthy gut lining
Sodium butyrate is used to help maintain the mucosal barrier in your intestines. This barrier acts as a selective filter, allowing nutrients to pass through whilst keeping harmful substances out.1
When the gut lining is functioning as it should, it supports overall digestive comfort and helps maintain balance in your gut environment. Butyrate plays an active role in supporting this protective barrier.2
Supporting a balanced inflammatory response
Sodium butyrate is recognised for its role in supporting a balanced immune response in the gut. The gut is home to a large portion of your immune system, and butyrate helps regulate immune activity in the intestinal lining.
By supporting this balance, sodium butyrate contributes to overall digestive wellness, particularly for those looking to maintain gut comfort and function.
Encouraging beneficial bacteria
Taking sodium butyrate may help create a more favourable environment for beneficial gut bacteria. Whilst butyrate is typically produced by these bacteria, supplementing with it can support their activity and help maintain microbial diversity.
This is especially relevant for individuals who are working to rebalance their gut microbiome after disruption from antibiotics, illness or dietary changes.
Supporting regularity and digestive comfort
Some people use sodium butyrate to support healthy bowel movements and overall digestive comfort. By nourishing colon cells and supporting gut motility, butyrate can contribute to more regular and comfortable digestion.
It's worth noting that sodium butyrate is not a laxative. Rather, it works by supporting the underlying health of your digestive system.
Helping with gut repair and recovery
Sodium butyrate is sometimes used as part of a gut repair protocol, particularly by people recovering from digestive disruption. Its role in nourishing colon cells and supporting the gut barrier makes it a useful addition when working to restore gut health.
It's often combined with other gut supporting strategies such as increasing fibre intake, reducing inflammatory foods and working with a qualified practitioner.
Who might use sodium butyrate?
People explore sodium butyrate for different reasons. Common scenarios include:
- Low fibre diets where natural butyrate production is reduced
- Post antibiotic recovery to support gut rebalancing
- Digestive wellness protocols focused on gut lining support
- Supporting overall microbiome health
- Addressing occasional digestive discomfort

How is sodium butyrate typically taken?
Sodium butyrate is most commonly taken in capsule form, usually with meals. Dosing varies depending on the product and individual needs, but many formulations contain between 300mg and 600mg per capsule.
Enteric coated or microencapsulated formulations are preferred as they protect the butyrate from being broken down too early, ensuring it reaches the colon where it's needed most.
Is sodium butyrate the same as eating fibre?
Not quite. Eating fibre encourages your gut bacteria to produce butyrate naturally, which is the ideal scenario. However, if your microbiome is imbalanced or you're not consuming enough fibre, your butyrate levels may be lower than optimal.
Sodium butyrate supplements provide a direct source of this compound, bypassing the need for bacterial fermentation. Think of it as a way to support your gut whilst you're working on improving your diet and microbiome health.
Sodium butyrate is used primarily to support colon health, maintain the gut lining and encourage a balanced digestive environment. It's a tool that can be particularly useful when natural butyrate production is compromised.
Whether you're exploring it as part of a gut repair protocol or simply looking to support your microbiome, understanding how sodium butyrate works can help you make informed decisions about your digestive wellness. Always choose high quality, enteric coated formulations and consult a knowledgeable practitioner if you're unsure where to start.
Frequently asked questions
What conditions can sodium butyrate help with?
Sodium butyrate is not a treatment for specific medical conditions. It's used to support general digestive wellness, particularly for people with compromised gut function, low fibre intake or an imbalanced microbiome. If you have a diagnosed condition, always work with a healthcare professional.1
How quickly does sodium butyrate work?
Results vary between individuals. Some people notice improvements in digestive comfort within a few days, whilst others may need several weeks of consistent use. Sodium butyrate works gradually to support gut cell health rather than providing instant symptom relief.2
Can I take sodium butyrate alongside probiotics?
Yes, sodium butyrate is often combined with probiotics as part of a comprehensive gut health strategy. Probiotics help populate your gut with beneficial bacteria, whilst butyrate provides fuel for your colon cells. They work well together.3
Is sodium butyrate better than increasing dietary fibre?
They serve different purposes. Dietary fibre feeds your gut bacteria, which then produce butyrate naturally. Sodium butyrate supplements provide the compound directly. Ideally, you'd do both: eat plenty of fibre and supplement with sodium butyrate if your natural production is low.4
Are there any side effects of taking sodium butyrate?
Sodium butyrate is generally well tolerated. Some people may experience mild digestive changes when first starting, particularly if they begin with a higher dose. These effects usually settle within a few days. If you experience persistent discomfort, reduce your dose or consult a healthcare professional.5
