The Active Ingredient Is: Glucoamylase

Glucoamylase is basically an enzyme that helps out in the final stages of carbohydrate digestion inside the small intestine. It helps with the breakdown of starches into smaller sugars, supporting the digestive process linked to carbohydrate metabolism.

This formula includes microbial-derived enzymes chosen for vegetarian capsules, with the broader blend designed to work beside other enzymatic activities to support digestive comfort and nutrient absorption.

What Does Glucoamylase Do?

Glucoamylase takes part in carbohydrate digestion by aiding the breakdown of complex carbohydrates at the brush border of the small intestine, contributing to the efficiency of starch conversion to simpler sugars.

This product's enzyme blend also contains proteases and disaccharidases which together support the digestion of proteins and sugars, aiming to promote normal digestive function and nutrient utilisation.

This supplement is not intended to diagnose, treat, cure, or prevent any disease.
