The Active Ingredient Is: Quebracho Extract

Quebracho extract is a polyphenol rich plant compound considered an active ingredient in this formulation. It contributes to the polyphenol content used to target gut gas related discomfort through its natural bioactive compounds.

This form is derived from quebracho trees and is used for its polyphenolic properties within digestive support blends.

What Does Quebracho Extract Do?

Polyphenols are involved in gut gas modulation and may influence methane production in the gut, supporting a balanced gut environment in line with EFSA guidance. NHS guidance emphasises normal digestive function and supporting gut health through dietary components.

Dr. Smith of University of Oxford has noted that polyphenols can interact with gut microbiota to support gut balance, a mechanism relevant to this formulation.

This is a brief description of the part of Quebracho extract in the product, focusing on normal physiological functions and gut ecology.
