Butyrate: The Gut Health Booster You’ve Probably Never Heard Of

What is Butyrate?

Butyrate is a type of short-chain fatty acid (SCFA) produced in your colon when gut bacteria ferment certain types of fibre, especially resistant starches. You can also find it in supplement form, but most people rely on their gut microbes to make it naturally.

Fun fact: butyrate is the main fuel source for your colon cells. In other words, it literally feeds the lining of your gut, helping to keep your digestive system strong and resilient.

Health Benefits of Butyrate

· Supports Gut Health: Butyrate keeps the gut lining healthy, reduces “leaky gut,” and helps maintain a balanced microbiome.

· Reduces Inflammation: Studies show butyrate can calm inflammation by promoting regulatory immune cells and lowering pro-inflammatory signals.

· Improves Metabolism: Early research suggests butyrate may improve insulin sensitivity, regulate blood sugar, and even support healthy cholesterol and triglyceride levels.

· Protects Against Colon Cancer: Lab studies show butyrate may help cancer cells self-destruct and reduce overall risk of colon cancer, though more human trials are needed.

· May Benefit the Brain: Through the gut-brain connection, butyrate might play a role in mood, memory, and even protection against neurological conditions.

How to Boost Butyrate Naturally.

1.Eat More Fibre-Rich Foods

Since butyrate is made from fibre fermentation, the best strategy is to feed your gut bacteria the right fuel:

— Resistant starches: cooked & cooled potatoes, green bananas, oats, barley

— Legumes: beans, lentils, chickpeas

— Vegetables: carrots, beetroot, sweet potato

— Whole grains: brown rice, barley

2. Go for Plant Variety

The more diverse your plant foods, the better for your microbiome. Aim for “30 different plants per week” as a fun challenge.

3. Add Prebiotics

Prebiotic fibres like inulin or fructooligosaccharides (FOS) specifically feed butyrate-producing bacteria. These include foods like garlic, onions, leeks, asparagus, green bananas, apples, and pears.

4. Limit Processed Foods

Highly processed foods and excess saturated fat can lower butyrate production, while antibiotics may wipe out butyrate-producing bacteria altogether.

Butyrate Supplements

For some people — especially those with gut health challenges — supplements can help top up butyrate levels.

Available on Nutrition Directory

On Nutrition Directory you’ll find:

1. CP Sodium Butyrate, a direct source of butyrate that can be taken alongside a fibre-rich diet for extra support. This can be especially helpful for people recovering from antibiotics, struggling with inflammatory gut issues, or wanting a targeted gut health boost.

2. Bettergut by Phytoceutics is a pre- and postbiotic supplement designed to support gut health more directly. It contains tributyrin (200 mg per capsule), a form of butyrate that helps deliver butyrate to the colon. In addition, it includes prebiotic fibres such as partially hydrolysed guar fibre and acacia fibre, which feed butyrate-producing bacteria. This creates a dual-action approach: direct butyrate delivery plus microbiome support. Helpful to support digestion, reduce bloating, strengthen the gut barrier, and promote immune, metabolic, and even skin and mood health. It is particularly useful for people with compromised microbiomes or those needing extra gut barrier support.

Butyrate may not be as well-known as probiotics, but it’s a gut superstar. By eating a fibre-rich, plant-diverse diet, you can naturally increase your body’s butyrate production — and if needed, supplements like sodium butyrate are available locally.

Healthy gut, happy you!
