Kemin Industries Launches ButiShield™ Encapsulated Butyrate for Humans to Provide Next-Generation Support for Gut Health and Beyond
Microencapsulated calcium butyrate provides sustained and controlled release of butyric acid in the gastrointestinal tract with superior handling and low odor

DES MOINES, Iowa, U.S. (October 3, 2023) – Kemin Industries, a global ingredient manufacturer that strives to sustainably transform the quality of life every day for 80 percent of the world with its products and services, has launched ButiShield, an encapsulated form of calcium butyrate for humans that can help fortify overall gut health by supporting the strength and integrity of the intestinal wall.

Butyric acid is an extensively researched short-chain fatty acid (SCFA) that plays an important role in intestinal health, which also extends to overall health and well-being. Despite its benefits, products containing butyrate have many formulation and operational challenges due to its unpleasant odor and difficult handling.

Kemin is producing ButiShield using proprietary MicroPEARLS spray freezing technology to encapsulate the butyric acid, allowing for sustained and controlled release along the gastrointestinal tract—and with easier handling due to its low odor. The MicroPEARLS encapsulation technology neutralizes butyric acid’s typically off-putting odor and helps to ensure its benefits are being delivered to the gut, where they’re most beneficial for the gastrointestinal tract health.

ButiShield is a low-odor, non-GMO, allergen-free, gluten-free, kosher, halal and vegetarian ingredient solution providing greater than 35% butyric acid.1 Butyrate provides science-based health benefits for intestinal and digestive health and works by:

  • Helping to shape a healthy microbiome and gastrointestinal environment2-5
  • Serving as a signaling molecule to regulate numerous metabolic processes at the cellular level6-9
  • Serving as a primary energy source for healthy intestinal cells10-15
  • Supporting intestinal barrier integrity10-15

“ButiShield is an exciting new offering for brands that are looking to reformulate or expand into the digestive health category,” said Chris Sadewasser, Global Product Manager, Kemin Human Nutrition and Health. “Our latest innovation delivers well-known butyric acid in a novel way to support a healthy gut, improve the consumer experience and help formulators overcome manufacturing challenges. Kemin has mastered encapsulation technology with cutting-edge MicroPEARLS, originally developed to support gut health in animals. Now, we’re elevating the proprietary application to reach a new level in human health, providing a unique solution to the evolving gut health market.”

ButiShield is a microencapsulated calcium butyrate that provides sustained and controlled release of butyrate and masks the odor typically associated with butyric acid to provide a better experience for consumers. Butyrate has well-established benefits to help support the intestinal barrier and promote gut health.
