ButiShield™ - Butyrate for the Intestine and Beyond

ButiShield™ is an encapsulated low odor source of calcium butyrate safe for daily consumption that provides a targeted release of >35% butyric acid.  Butyrate is a short chain fatty acid with science-based health benefits for strength, health, and integrity of the intestinal wall, leading to extra-intestinal health benefits.

Butyrate works by serving as a primary energy source for healthy intestinal cells and supports intestinal barrier integrity1-5. Butyrate also works by helping shape a healthy microbiome and gastrointestinal environment6-9 and serves as a signaling molecule to regulate numerous metabolic processes at the cellular level10-15.

ButiShield may offer the following benefits*:

  • Helps shape a healthy microbiome and gastrointestinal environment7-9
  • Primary energy source for healthy intestinal cells2-5
  • Support of a healthy intestinal barrier integrity2-5
  • Promotes a healthy gastrointestinal environment6-9

Next Generation Encapsulation Technology

ButiShield is produced using MicroPEARLS®,  a proprietary spray-freezing technology which helps to mask the typical unpleasant odor of butyric acid and promote a targeted, slow release in the gastrointestinal (GI) tract to deliver butyric acid where it delivers maximum benefit. For over 60 years, Kemin has designed, finetuned, validated and mastered our encapsulation technologies. Our cutting edge MicroPEARLS technology with butyrate has serviced the animal health industry for years and today Kemin has elevated it to the next level in human health.
