Product overview

Doctor’s Best PepZin GI® is an exclusive, patented complex of zinc and L-carnosine that was first developed in Japan and has been in use since 1994. This special chelated form of the mineral zinc has a unique ability to exert its effects directly on the cells of the stomach lining. When the zinc is complexed to L-carnosine, it dissociates in the stomach at a slower rate. This prolonged existence allows it to maintain its gastric support effect over a longer period of time. The proprietary chelation process along with excellent research make PepZin GI® your best choice for supporting gastric health!

  • Supports occasional gastric discomfort.
  • Helps support a healthy GI environment.
  • Offers support healthy mucosal lining.
What is zinc-carnosine?

Zinc is an essential trace element and a component in more than 300 biochemical reactions. It plays a role in DNA and RNA synthesis, which is significant for tissue repair. Carnosine is a naturally occurring protein composed of the amino acids, L-histidine and B-alanine, which can form stable complexes with minerals such as zinc.

Zinc-carnosine is produced when zinc and carnosine are bound together to create a chelate compound. This compound has been found to be three times more effective than supplementing with either zinc or L-carnosine individually.

Why zinc-carnosine?

Carnosine and zinc both have tissue integrity supportive properties, therefore the two combined can significantly support the gastric lining. Zinc-carnosine is insoluble in water, heat stable, does not quickly lose its potency and temperature changes do not affect its ability.
