Prednisolone and Vitamin D3: what the published research says
PubMed indexes 6 records that name Prednisolone 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.
Every statement below is attributed to a named, dated, linked source.
This page lists published research relevant to Prednisolone 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.
A study appearing here is not proof that an interaction exists. Two substances can be named together in a paper that never tested them in combination, and a source listed as background may cover only one of them.
Findings are quoted from each abstract as the authors wrote them. NutriStack has not re-analysed, pooled, or reconciled them, and they may disagree with each other.
NutriStack’s own interaction assessment for this pair is not published here. It has not completed qualified-human clinical review, so it is withheld from search. See the publication gate.
Nothing here is medical advice. Decisions about prescription medication and supplements belong with your prescriber or pharmacist, who can see your full regimen.
The research
6 studies naming Prednisolone and Vitamin D3.
Strongest relevance first: papers naming both substances in the title, then human trials and systematic reviews.
European review for medical and pharmacological sciences · 2016 · PMID 27097962
Animal study
“These data suggest that vitamin D3 and α-tocopherol can prevent immunosuppressive effects of prednisolone through elevating the efficacy of oxygen-dependent mechanisms of phagocytosis and increasing the functional activity of phagocytic cells.”
Names both Prednisolone and Vitamin D3 in its title.
“Vitamin D3 (and to greater extent in combination with α-tocopherol) administration (100 IU) on the background of glucocorticoid therapy caused normalizing effects on the level of ROS formation, oxidative modification of biomolecules and activity of antioxidant enzymes resulting in better survival of hepatocytes. These data suggest a potential role of vitamin D3 in the regulation of oxidative metabolism alterations related to hepatotoxic action of glucocorticoids.”
Names both Prednisolone and Vitamin D3 in its title.
“Prednisolone administration resulted in the lowering of both mitochondrial and microsomal isoenzymes of vitamin D3 25-hydroxylase. The inhibition of vitamin D3 25-hydroxylating system in hepatocytes contributed to a significant reduction in blood serum 25OHD3.”
Names both Prednisolone and Vitamin D3 in its title.
The Journal of rheumatology. Supplement · 2005 · PMID 16142847
Comparative StudyHuman subjects
“In conclusion, improvement in bone turnover, increase in BMD, and reduction in fracture rates have been described during alfacalcidol treatment in situations characterized by a high rate of bone loss, including CS-induced osteoporosis, early postmenopausal bone loss, and organ transplant. Compared to plain vitamin D, alfacalcidol exerts higher bone-protective effects, thus allowing the doses to be minimized and lowering the risk of adverse effects, including hypercalcemia.”
Names Prednisolone and Vitamin D3 together in an interaction, co-administration, or pharmacokinetic context.
“High clinical efficiency and absence of side effects recommend calcium-D3 Nikomed for management of steroid osteoporosis in patients with hormone-dependent bronchial asthma.”
Names Prednisolone and Vitamin D3 together in an interaction, co-administration, or pharmacokinetic context.
The Journal of steroid biochemistry and molecular biology · 1998 · PMID 9569012
Comparative StudyAnimal study
Names Prednisolone and Vitamin D3 together in an interaction, co-administration, or pharmacokinetic context.
Limitations
What this evidence cannot tell you.
Search-based evidence indexes have real limits, and it is worth being explicit about them:
Selection. These records were found by searching PubMed titles and abstracts for both substance names alongside interaction and pharmacokinetic terms. Relevant work that phrases things differently, or is not indexed in PubMed, will be missing.
No effect size. The quoted conclusions are the authors’ words about their own study. We have not extracted effect direction or magnitude, and a single study’s conclusion is not a consensus.
Population mismatch. Findings in healthy volunteers, animals, or a specific patient group may not transfer to you, your dose, or your formulation.
Absence is not safety. Few published studies means the combination is under-studied, which is not the same as established as safe.

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 Prednisolone, 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.
