Alendronate and Vitamin D3: what the published research says

PubMed indexes 8 records that name Alendronate and Vitamin D3 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.

An evidence index, not guidance.

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

This page lists published research relevant to Alendronate and Vitamin D3. 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 Alendronate and Vitamin D3.

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

Oral administration of alendronate and vitamin D3 for the treatment of chronic non-bacterial osteomyelitis of the jaw.

International journal of oral and maxillofacial surgery · 2020 · PMID 32680809

Case ReportsHuman subjects

“The patient exhibited a favourable response to oral alendronate sodium plus vitamin D3 combination treatment. We believe that alendronate sodium is an effective second-line drug for CNO.”

Yang et al. · From the abstract

Names both Alendronate and Vitamin D3 in its title.

Effects of alendronate and calcifediol compared to alendronate and cholecalciferol in osteoporotic patients.

Minerva endocrinologica · 2019 · PMID 31971357

Multicenter StudyHuman subjects362 participants

“Alendronate 70 mg with calcifediol gives a better outcome in the treatment of osteoporosis according to lumbar T-score and vitamin D serum level observed at one-year follow-up compared to alendronate 70 mg with cholecalciferol. Both vitamin D formulations did not show to cause hypercalcemia in this study. Alendronate 70 mg in drinkable solution form is also associated with lowest incidence of gastrointestinal adverse reactions.”

GiampĂ  et al. · Authors' conclusion

Names both Alendronate and Vitamin D3 in its title.

Alendronate sodium/vitamin D3 combination tablet versus calcitriol for osteoporosis in Chinese postmenopausal women: a 6-month, randomized, open-label, active-comparator-controlled study with a 6-month extension.

Osteoporosis international : a journal established as result of cooperation between the European Foundation for Osteoporosis and the National Osteoporosis Foundation of the USA · 2015 · PMID 25929192

Comparative StudyMulticenter StudyRandomized Controlled Trial219 participants

“ALN/D5600 produced greater increases in lumbar spine BMD and greater decreases in bone turnover markers versus calcitriol in osteoporotic Chinese women. It is not known whether the greater increase in BMD results in fewer fractures. ALN/D5600 was generally well tolerated in Chinese patients.”

Zhang et al. · Authors' conclusion

Names both Alendronate and Vitamin D3 in its title.

Alendronate with and without cholecalciferol for osteoporosis: results of a 15-week randomized controlled trial.

Current medical research and opinion · 2006 · PMID 16968578

Clinical TrialMulticenter StudyRandomized Controlled Trial

“In osteoporosis patients who avoided sunlight and vitamin D supplements, this once-weekly tablet containing alendronate and cholecalciferol provided equivalent antiresorptive efficacy, reduced the risk of low serum 25OHD, improved vitamin D status over 15 weeks, and was not associated with hypercalcemia, hypercalciuria or other adverse findings, versus alendronate alone.”

Recker et al. · Authors' conclusion

Names both Alendronate and Vitamin D3 in its title.

Safety and effects of calcifediol 0.266 milligrams soft capsules monthly and cholecalciferol 25000 international units monthly in osteoporotic women undergoing therapy with alendronate: a cross-sectional study.

Minerva endocrinology · 2024 · PMID 38576377

Human subjects

“In our study calcifediol showed to be as safe as cholecalciferol and more effective than cholecalciferol in order to increase vitamin D serum level after four and 12 months of supplementation when supplementation is combined with alendronate 70 mg in osteoporotic women.”

GiampĂ  et al. · Authors' conclusion

Names both Alendronate and Vitamin D3 in its title.

Efficacy of the systemic co-administration of vitamin D3 in reversing the inhibitory effects of sodium alendronate on orthodontic tooth movement: A preliminary experimental animal study.

American journal of orthodontics and dentofacial orthopedics : official publication of the American Association of Orthodontists, its constituent societies, and the American Board of Orthodontics · 2022 · PMID 35501223

Animal study

“Systemic vitamin D3 may accelerate OTM and increase histologic biomarkers of bone turnover. ALN reduces OTM and its histologic biomarkers. Systemic vitamin D3 can reverse this inhibitory effect of ALN on OTM back to normal.”

Moradinejad et al. · Authors' conclusion

Names both Alendronate and Vitamin D3 in its title.

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 Alendronate, Vitamin D3, 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.
