What prednisone can deplete.
Nutrients this medication is associated with lowering over time, with the mechanism, a suggested replacement where one applies, and the biomarker to monitor. Discuss any replacement with your prescriber first.
| Nutrient | Severity | How it happens | Replace with | Monitor |
|---|---|---|---|---|
| Calcium | Significant | Glucocorticoids reduce intestinal calcium absorption, increase urinary calcium loss, and accelerate bone resorption. | Calcium | Serum calcium or bone density trend |
| Vitamin D | Moderate | Glucocorticoids impair activation and signaling of vitamin D, reducing calcium absorption and bone support. | Vitamin D3 | 25-OH vitamin D |
| Potassium | Moderate | Systemic corticosteroids can promote potassium loss or shifts in susceptible patients, especially at higher doses or with other hypokalemia risks;... | Clinician-guided potassium repletion if serum potassium is low | Serum potassium + kidney function |
| Magnesium | Moderate | Chronic corticosteroid use can increase urinary magnesium losses and worsen low magnesium status. | Magnesium Glycinate | Serum magnesium or RBC magnesium |

Does Prednisone deplete any nutrients?
Prednisone is associated with lowering Calcium, Vitamin D, Potassium, and Magnesium with prolonged use. Useful biomarkers to monitor include Serum calcium or bone density trend, 25-OH vitamin D, and Serum potassium + kidney function. Ask your prescriber before adding any replacement supplement.
Is it safe to take Strontium with Prednisone?
NutriStack classifies the Strontium and Prednisone pairing as caution: Prednisone can cause clinically important bone loss when used chronically. Strontium supplements may make DXA bone density results look higher because strontium in bone... Do not use strontium as a substitute for guideline-based prednisone bone protection. Tell your clinician and imaging center if you use strontium,... Always confirm with your prescriber.
