1. Promotes Healthy Gut Microbiome: ButyrAid / ButyrEn contains butyric acid, a short-chain fatty acid that plays a crucial role in maintaining a healthy balance of bacteria in the gut. This can improve digestion and prevent various digestive issues such as bloating, gas, and constipation.
2. Supports Immune System Function: Butyric acid has been shown to have anti-inflammatory and immune-regulating properties. By promoting the growth of beneficial bacteria in the gut, ButyrAid / ButyrEn can help boost the body's immune response and protect against infections and diseases.

The Active Ingredient Is: Butyrate (Tributyrin Complex)

Butyrate is basically a short-chain fatty acid that acts as the main energy source for colonocytes, and helps keep the gut lining healthy.

This formula uses a tributyrin complex delivered in delayed-release vegetarian capsules to target the colon and improve delivery while minimising gas or bloating, compared with other delivery options.

What Does Butyrate Do?

Butyrate helps provide energy to colonocytes, aids the repair of the intestinal lining, and is involved in modulating gut immune signals, supporting a healthy gut environment.

Dr. Canani from the University of Naples Federico II found that butyrate supports the gut lining and reduces inflammation, which helps explain its role in colon health and digestive comfort.
