Revolutionizing Gut Health: Introducing ButiShield™ – Kemin's Breakthrough in Microencapsulated Calcium Butyrate

Posted December 19, 2023

At Kemin Industries, our commitment to sustainably transforming lives drives us to constantly innovate and overcome challenges in the nutraceutical industry. We are thrilled to introduce our latest breakthrough – ButiShield™, an encapsulated form of calcium butyrate designed specifically for humans, designed to fortify overall gut health. In this blog post, we'll delve into the details of ButiShield™ and explore how it addresses common challenges faced by supplement manufacturers.

The Butyric Acid Advantage:

Butyric acid, an extensively researched short-chain fatty acid (SCFA), is a key player in intestinal health, influencing overall well-being. Despite its remarkable benefits, the incorporation of butyrate into products has been hindered by formulation and operational challenges, primarily due to its unpleasant odor.

The Innovation: ButiShield™ with MicroPEARLS™ Technology

To overcome these challenges, Kemin is proud to present ButiShield™, crafted using our patented MicroPEARLS spray freezing technology. This innovative approach involves encapsulating butyric acid which ensures a sustained and controlled release along the gastrointestinal tract . Notably, MicroPEARLS™ technology also addresses the handling issue by significantly reducing the odor associated with butyric acid.

Key Features of ButiShield™:

Low Odor: MicroPEARLS™ encapsulation technology neutralizes the typically off-putting odor of butyric acid, providing a more pleasant experience for consumers.

Versatile Solution: ButiShield™ is a low-odor, non-GMO, allergen-free, gluten-free, kosher, halal, and vegetarian ingredient solution, offering greater than 35% butyric acid.

Science-Backed Benefits:

ButiShield™, with its microencapsulated butyrate delivers a vital metabolite of fiber fermentation with robust scientific validation. It works by:*1-8

  1. Shaping a Healthy Microbiome: Contributing to the creation of a healthy gastrointestinal environment.
  2. Cellular Regulation: Serving as a signaling molecule to regulate numerous metabolic processes at the cellular level.
  3. Energy Source: Serving as a primary energy source for healthy intestinal cells.
  4. Intestinal Barrier Support: Supporting intestinal barrier integrity.


As a leading global ingredient manufacturer, Kemin is proud to present ButiShield™ as a game-changer in the digestive health category. This microencapsulated calcium butyrate opens new possibilities for supplement manufacturers, providing a unique solution to the evolving gut health market. With ButiShield™, we're not just addressing challenges; we're revolutionizing gut health and offering a novel approach to incorporating butyrate into formulations.
