Corticosteroid Interactions: Calcium+D To Save Your Bones, Magnesium To Boost Effectiveness

Drug-Induced Nutrient Depletions

  • Calcium: Corticosteroids can reduce calcium absorption, increasing the risk of osteoporosis and bone fractures. Calcium supplementation may be recommended to counteract this effect. [PMID: 8899087, PMID: 3728366]
  • Vitamin D: These medications can alter vitamin D metabolism, further contributing to bone health issues. Supplementing with vitamin D can help maintain its optimal levels in the body. [PMID: 8967706]
  • Magnesium: Corticosteroids may lower magnesium levels. A recent analysis found that long‐term magnesium supplementation of 350 mg/day improves glucocorticoid metabolism. [PMC7821302]

Supplement-Drug Interactions:

  • Vitamin C: High doses of vitamin C might interact with the absorption or effectiveness of corticosteroids.
  • St. John’s Wort: This supplement may reduce the effectiveness of corticosteroids.
  • Potassium: Corticosteroids can cause potassium depletion. Supplementation or consuming potassium-rich foods may be necessary.
