Carnosine and Zinc: what the published research says

PubMed indexes 8 records that name Carnosine and Zinc together, either in the title or in an interaction, co-administration, or pharmacokinetic context. Each one is listed below with its study design and, where the abstract states one, the authors’ own conclusion, quoted and linked. This page reports that literature. It does not tell you whether to combine them.

Read this first

An evidence index, not guidance.

Every statement below is attributed to a named, dated, linked source.

This page lists published research relevant to Carnosine and Zinc. It deliberately does not state whether the combination is safe, whether it interacts, in which direction, at what dose, or how far apart to take them.

The research

8 studies naming Carnosine and Zinc.

Strongest relevance first: papers naming both substances in the title, then human trials and systematic reviews.

Zinc-L-Carnosine (Polaprezinc) in managing infant regurgitation: a two-center randomized controlled trial.

Frontiers in pediatrics · 2026 · PMID 42093671

Clinical Trial

“Zinc-L-carnosine is a safe and effective alternative to thickened formula in treating persistent infant regurgitation, after the failure of non-pharmacological measures. Its lower cost and promising clinical effect support further investigation in larger pediatric cohorts.”

Piccirillo et al. · Authors' conclusion

Names both Carnosine and Zinc in its title.

Improvement in Chronic Atrophic Gastritis After Treatment with Zinc L-Carnosine.

The American journal of case reports · 2025 · PMID 41264559

Case ReportsHuman subjects

“CONCLUSIONS These case reports suggest that zinc L-carnosine can improve both dyspeptic symptoms and histologic features of CAG, thereby potentially reducing progression to gastric cancer. Larger clinical studies are warranted to confirm these findings.”

De Bastiani et al. · From the abstract

Names both Carnosine and Zinc in its title.

Dissociative Identity Disorder Cotreated With Zinc and L-carnosine: A Case Report.

Cureus · 2024 · PMID 39737293

Case Reports

“The physical symptoms of zinc deficiency eventually resolved. Further investigation of cotreatment with zinc and L-carnosine for DID and related conditions, particularly the contribution of zinc deficiency to dissociation, is necessary.”

Sakae et al. · From the abstract

Names both Carnosine and Zinc in its title.

The Role of Zinc in the Development of Vascular Dementia and Parkinson's Disease and the Potential of Carnosine as Their Therapeutic Agent.

Biomedicines · 2024 · PMID 38927502

Review

“Carnosine may be a therapeutic drug for VD and PD. Furthermore, we reviewed the molecular mechanisms that involve the role of carnosine as an endogenous protector and its protective effect against Zn2+-induced cytotoxicity and discussed the prospects for the future therapeutic applications of this dipeptide for neurodegenerative diseases and dementia.”

Mizuno et al. · From the abstract

Names both Carnosine and Zinc in its title.

Carnosine, Zinc and Copper: A Menage a Trois in Bone and Cartilage Protection.

International journal of molecular sciences · 2023 · PMID 38003398

ReviewHuman subjects

“We hypothesize that polaprezinc could exchange Zn for Cu, present in the culture media, due to its higher sequestering ability towards Cu. However, future studies should unveil the potential contribution of Cu in the beneficial effects of polaprezinc.”

Ciaffaglione et al. · From the abstract

Names both Carnosine and Zinc in its title.

Limitations

What this evidence cannot tell you.

Search-based evidence indexes have real limits, and it is worth being explicit about them:

NutriStack

Track what you actually take.

NutriStack is a free iPhone app for organising a supplement routine: what you take, when, and what the published record says about it. Its exploratory interaction checker covers Carnosine, Zinc, and several hundred other substances.

The checker is a research and organisation tool, not a clinical decision aid, and its per-pair assessments are excluded from search until they pass claim-level review.
