**Zinc-L-Carnosine** at 75mg per serving — right at the top of the clinically studied dose range for gut lining support. This is the patented PepZin GI form, a chelate that sticks to your stomach wall and delivers zinc and carnosine directly where they're needed. It's been used as a prescription gastroprotective in Japan since 1994, and the research supports its role in protecting your gut lining from stress- and NSAID-related damage.

You're also getting 16mg of elemental **zinc** per serving, which falls within the supplemental range and contributes to immune function and skin health. The zinc here isn't free-floating — it's bound to **L-carnosine** as part of the chelate, so it behaves differently than a standard zinc supplement and targets the GI tract specifically.

The 59mg of **L-carnosine** in this complex is far below standalone carnosine doses used for anti-aging or cognitive research (500–1,500mg), so don't expect those benefits here. This product is built for one job — stomach and gut lining support — and the dosing matches the clinical evidence for that purpose.
