The Active Ingredient Is: Amylase (Digestive Enzyme)

Amylase is a digestive enzyme that helps break down starches in the gut, supporting normal digestion of carbohydrates. This form is sourced from a microbial source and works alongside other enzymes to help digestion and nutrient absorption.

This ingredient is part of a wider vegetarian enzyme blend that includes extra enzymes to support the breakdown of different macronutrients and fibres, helping the body process meals more efficiently.

What Does Amylase Do?

Amylase helps with carbohydrate digestion by breaking down starches into smaller sugar units, supporting normal energy utilisation and nutrient absorption. This function aligns with EFSA guidance on digestive enzyme activity and routines in the gut.

Dr. Azpiroz of the University of Barcelona found that enzymes in this type of digestive blend show activity across the whole pH range of the digestive tract, which helps explain their role in supporting meal processing.
