Beyond the bacteria. Discover what makes them matter.

Probiotics introduce beneficial microbes. Prebiotic fibres help nourish them. But an important part of the story is what those microbes produce: short-chain fatty acids, including butyrate. These compounds help connect a thriving microbiome with a well-nourished gut lining.

Allergy Research Group ButyrEn® puts this valuable microbial metabolite centre stage. Featuring 200 mg of ButyraGen™ Tributyrin Complex per capsule with BioVXR acid-resistant capsule technology, it supplies a source of butyrate to complement your gut’s natural production.

Butyrate: a main event in colon health

Your colon lining is living, active tissue, constantly maintaining and renewing itself. Butyrate is a preferred fuel for colonocytes, the cells lining your colon. It helps supply the energy these cells need for normal function and renewal, supporting the tissue that separates the contents of your gut from the rest of your body.

This is why gut health is about more than adding bacteria. It is also about nourishing the environment those bacteria call home, including the lining itself.

Help create an environment where beneficial microbes can thrive

Butyrate does more than supply energy. When colonocytes metabolise it, they consume oxygen, helping maintain the naturally low-oxygen conditions within a healthy colon. Many beneficial gut microbes thrive in this environment, while excess oxygen can favour the expansion of certain potentially harmful bacteria.

Alongside other short-chain fatty acids, butyrate also contributes to the colon’s acidic environment. Together, these processes help shape an ecology that favours beneficial microbial communities and can make conditions less favourable for some unwanted organisms. It is support for the ecosystem, not simply another addition to it.

Focused support for your gut-health foundation

• Fuel for your colon lining: Provides a source of butyrate, an important energy substrate for colonocytes.
• Support for normal renewal and barrier integrity: Helps nourish the cells that maintain your intestinal lining.
• A healthier microbial environment: Butyrate metabolism helps sustain the low-oxygen conditions associated with a balanced colonic ecosystem.
• Tributyrin-based delivery: Digestive enzymes break down tributyrin to release butyrate, complementing the supply naturally produced through fibre fermentation.
• Acid-resistant capsule technology: BioVXR capsules are designed to resist stomach acid, adding a protective delivery feature to the formula.

Why tributyrin?

Tributyrin links three butyrate units to a glycerol backbone, creating a fat-based precursor from which butyrate is released during digestion. ButyrEn pairs this form with acid-resistant capsule technology in a convenient formula for everyday gut-health support. Each capsule contains 200 mg of the ButyraGen complex.

Think beyond replenishing your microbiome. Nourish the foundation that helps it flourish. ButyrEn complements a varied, fibre-rich diet and a considered approach to digestive wellbeing.
