Quick Summary

Zinc carnosine (also called polaprezinc) is a chelated compound of zinc and L-carnosine. It’s one of the most evidence-based supplements for gastric and intestinal health — yet most people have never heard of it.

DetailInfo
Best ForGastric ulcers, leaky gut, H. pylori, NSAID gut damage
Effective Dose75mg 2x/day (providing 16mg elemental zinc + 59mg L-carnosine)
Onset2-4 weeks for symptom relief
SafetyExcellent — used as a prescription drug in Japan since 1994
Unique FeatureAdheres to ulcerated tissue, delivering zinc directly to damaged areas

What Is Zinc Carnosine?

Zinc carnosine is a 1:1 chelate of zinc and L-carnosine. Unlike regular zinc supplements, zinc carnosine has a unique property: it adheres to ulcerated or inflamed tissue in the stomach and intestinal lining, delivering zinc directly where it’s needed most.

This is why it outperforms regular zinc supplements for gut health — it doesn’t just raise systemic zinc levels, it targets the damaged tissue specifically.

In Japan, zinc carnosine has been approved as a prescription drug (Promac®) for treating gastric ulcers since 1994. It’s available as a dietary supplement in the US and Europe.

How It Works

  1. Mucoadhesion: Zinc carnosine binds to ulcerated or inflamed GI tissue, creating a protective barrier
  2. Zinc release: Zinc is slowly released at the site of damage, supporting wound healing and cell proliferation
  3. Carnosine release: L-carnosine provides antioxidant protection and anti-inflammatory effects at the tissue level
  4. Tight junction support: Zinc carnosine strengthens tight junctions between intestinal cells, reducing intestinal permeability (“leaky gut”)
  5. COX-2 upregulation: Unlike NSAIDs (which inhibit COX-2), zinc carnosine upregulates COX-2, promoting mucosal defense and repair

Clinical Evidence

1. Gastric Ulcers

2. H. pylori

3. NSAID-Induced Gut Damage

4. Leaky Gut (Intestinal Permeability)

5. Oral Mucositis

Zinc Carnosine Dosage

ConditionDoseDurationTiming
Gastric ulcers75mg 2x/day8-12 weeksBefore meals
H. pylori adjunct75mg 2x/day7-14 days (with antibiotics)Before meals
Leaky gut75mg 2x/day6-12 weeksBefore meals
NSAID protection75mg 2x/dayWhile taking NSAIDsBefore meals

Important: Take zinc carnosine on an empty stomach (30 min before meals). Food reduces its mucoadhesive properties.

Zinc Carnosine vs Regular Zinc

Bottom line: If your primary goal is gut healing, zinc carnosine is far superior to regular zinc. If you need to correct systemic zinc deficiency, use zinc picolinate or glycinate.

Side Effects & Safety

Zinc carnosine is very well-tolerated:

Zinc intake: Each 75mg zinc carnosine provides ~16mg elemental zinc. At 75mg 2x/day, total zinc intake is ~32mg/day — well within the tolerable upper limit of 40mg/day.

Copper consideration: Zinc supplementation can reduce copper absorption. If taking zinc carnosine long-term (>3 months), consider adding 1-2mg copper daily.

The Bottom Line

Zinc carnosine is one of the most underrated supplements for gut health. It has 30+ years of clinical use in Japan, strong evidence for gastric ulcers, H. pylori, leaky gut, and NSAID protection — and it’s available without a prescription.

If you have any gut issues — from occasional heartburn to diagnosed ulcers to leaky gut — zinc carnosine deserves a place in your supplement stack.

Dose: 75mg twice daily on an empty stomach. Give it 4-8 weeks for full effects.
