Free · No account · based on published sources including NIH ODS, FDA drug labels, and peer-reviewed literature
Consider supplementing with 500–1000 mg of Vitamin C daily during corticosteroid therapy. Eat vitamin C-rich foods such as citrus fruits, bell peppers, and broccoli regularly.
Why this interaction occurs
Corticosteroids increase oxidative stress and accelerate ascorbic acid turnover and urinary excretion. Vitamin C depletion reduces collagen synthesis, impairs wound healing, and weakens antioxidant defense — effects that compound the immunosuppressive and tissue-thinning effects of methylprednisolone.
Evidence
Evidence level: moderate.
