Methylprednisolone and Vitamin D2, a synergy.
Chronic methylprednisolone exposure can reduce bone density and raise fracture risk. Vitamin D2 can help maintain vitamin D status and calcium absorption, which are core parts of glucocorticoid-induced osteoporosis prevention.

Synergy
What is happening. Chronic methylprednisolone exposure can reduce bone density and raise fracture risk. Vitamin D2 can help maintain vitamin D status and calcium absorption, which are core parts of glucocorticoid-induced osteoporosis prevention.
Mechanism. Systemic glucocorticoids suppress bone formation, increase bone resorption, and impair calcium balance. Vitamin D2 increases 25-OH vitamin D availability and supports calcium absorption.
Recommendation. If methylprednisolone is used beyond a short course, maintain vitamin D status and ask whether bone density testing or prescription osteoporosis prevention is appropriate. Vitamin D2 should complement calcium intake and risk-based treatment decisions, not replace them.
