Calcium and Esomeprazole: what the published research says

PubMed indexes 5 records that name Calcium and Esomeprazole 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 Calcium and Esomeprazole. 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

5 studies naming Calcium and Esomeprazole.

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

Co-administration of calcium carbonate or sodium bicarbonate prevents esomeprazole-induced osteoporosis.

Scientific reports · 2026 · PMID 42162236

“The co-administration of calcium carbonate and sodium bicarbonate effectively attenuated these deleterious effects. Notably, the comparable efficacy of sodium bicarbonate suggests that buffering systemic acidity may be a viable strategy for mitigating PPI-induced osteoporosis.”

Lim et al. · From the abstract

Names both Calcium and Esomeprazole in its title.

Different elemental infant formulas show equivalent phosphorus and calcium bioavailability in healthy volunteers.

Nutrition research (New York, N.Y.) · 2021 · PMID 33450668

Randomized Controlled Trial

“Serum calcium concentrations (GMR: AUC0-360 = 1.002 (0.996-1.009); Cpeak = 0.991 (0.983-0.999)) and urinary creatinine-corrected calcium excretion (GMR: AUC70-370 = 1.117 (1.023-1.219); Cpeak = 1.157 (1.073-1.247)) demonstrated bioequivalence of the products. In conclusion, both elemental infant formulas showed equivalent serum phosphorus and calcium bioavailability in healthy volunteers even if combined with treatment with acid-suppressive medication.”

Bergwitz et al. · From the abstract

Names Calcium and Esomeprazole together in an interaction, co-administration, or pharmacokinetic context.

Dexlansoprazole and Esomeprazole Do Not Affect Bone Homeostasis in Healthy Postmenopausal Women.

Gastroenterology · 2019 · PMID 30445008

Multicenter StudyRandomized Controlled Trial

“In a prospective study of postmenopausal women, we found significant increases in markers of bone turnover in women given PPI therapy compared with women given placebo, but levels remained within the normal reference range. We found no significant differences among groups in changes in BMD, PTH, serum or urine levels of minerals, or TFCA. Our findings indicate that 26 weeks of treatment with a PPI has no clinically meaningful effects on bone homeostasis.”

Hansen et al. · Authors' conclusion

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 Calcium, Esomeprazole, 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.
