The Active Ingredient Is: Zinc (Zinc Carnosine Complex, PepZinGI)

Zinc carnosine complex is basically a zinc-containing chelated compound that supports normal gastrointestinal function. This form combines zinc with the dipeptide carnosine to form a stable complex used for GI protection. L-glutamine is also included in the formulation to support intestinal cell function and mucosal integrity.

This combination aims to protect the stomach and small intestine lining and to support mucosal health through its constituent ingredients and evidence-based roles.

What Does Zinc (Zinc Carnosine Complex, PepZinGI) Do?

Zinc carnosine helps promote mucus secretion and provides antioxidant activity, which can contribute to protecting gastrointestinal tissues and supporting mucosal integrity. It may modulate inflammatory signals in line with GI health research, while the L-glutamine component supports enterocyte function and mucosal barrier maintenance as described in the evidence base.

Overall, the formulation focuses on maintaining normal GI function and tissue protection through the combined actions of zinc carnosine and L-glutamine.
