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.

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 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.

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.

Effects of vitamin D3 and vitamin E on prednisolone-induced alterations of phagocyte function.

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.”

Shymanskyy et al. · Authors' conclusion

Names both Prednisolone and Vitamin D3 in its title.

The ROS-generating and antioxidant systems in the liver of rats treated with prednisolone and vitamin D3

Ukrainian biochemical journal · 2014 · PMID 25816595

Animal study

“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.”

Shymans'kyĭ et al. · From the abstract

Names both Prednisolone and Vitamin D3 in its title.

Cholecalciferol hydroxylation in rat hepatocytes under the influence of prednisolone

Ukrains'kyi biokhimichnyi zhurnal (1999 ) · 2013 · PMID 23940873

Animal study

“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.”

Khomenko · From the abstract

Names both Prednisolone and Vitamin D3 in its title.

Importance of alfacalcidol in clinical conditions characterized by high rate of bone loss.

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.”

Reginster et al. · From the abstract

Names Prednisolone and Vitamin D3 together in an interaction, co-administration, or pharmacokinetic context.

Efficiency of calcium and vitamin D3 in the treatment of steroid osteoporosis in patients with hormone dependent bronchial asthma

Terapevticheskii arkhiv · 1999 · PMID 10626343

Comparative StudyHuman subjects20 participants

“High clinical efficiency and absence of side effects recommend calcium-D3 Nikomed for management of steroid osteoporosis in patients with hormone-dependent bronchial asthma.”

Ememl'ianov et al. · Authors' conclusion

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:

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 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.
