Estar® products contain esterified butyric acid, eliminating many of the historic issues surrounding butyrate supplementation: corrosiveness, odors, extensive upper gut absorption, and dilution of active ingredients by coating materials.

Estar® TEB has a market-leading concentration of 54% butyrate, delivered as esterified tributyrins.  This ensures a gradual, targeted release of butyric acid and monobutyrins throughout the intestines and cecum – where it can do the most good.  It also offers greater intestinal anti-bacterial activity than calcium- and sodium-based products.  Estar® TEB is an easy-to-handle free-flowing powder with no odor and no volatilization loss, and is water-insoluble.
