Butyric Acid – A Foundation For A Healthy Gut

ButiPEARL™ is an encapsulated source of butyric acid manufactured using a proprietary spray freezing process. MicroPEARLS® spray freezing technology allows for the slow release in the GI tract promoting an efficient use of butyric acid in swine and poultry. The encapsulation process greatly reduces the odor typically associated with butyric acid.    

Role of Butyric Acid in Digestion

Butyric acid is one of the short-chain fatty acids (SCFA) most efficiently used by the epithelial cells of the gastrointestinal (GI) tract. Butyric acid promotes the growth of tissues lining the GI tract and development of the intestinal epithelium in monogastric animals.1,2

Benefits of Butyric Acid

  • Cellular signaling to enterocytes1

  • Improves tight junctions in the intestines2

  • Increases antioxidant levels to promote healing in the GI tract2

  • Improves intestinal development3

  • Modulates immune response4

  • Reduces inflammation4

Delivering butyric acid at the right place, right time

A fat matrix surrounds the butyric acid ensuring the MicroPEARLS is not digested immediately; it is the delivery system for the active material.

  • Particles of butyric acid salt are embedded in the MicroPEARLS matrix during the manufacturing process. Particles are released in the presence of an aqueous environment, leaving holes to new unexposed particles.

  • Liquid enters through exterior holes into the pearls and contacts the other particles of butyric acid. These particles are then released leaving new holes, as liquid contacts them. In the end, pearls look like empty shells.

  • The released material disassociates into butyric acid and calcium. The butyric acid can be absorbed by the epithelial cells of the intestinal tract. The calcium is also absorbed while the fat matrix is excreted.
