NutriStack
Calcium and Zoledronic Acid, a synergy.
Zoledronic acid rapidly suppresses bone resorption and can drive serum calcium down within days of infusion, especially in patients with low calcium intake, vitamin D deficiency, or impaired renal function. Adequate calcium intake is required by major osteoporosis guidelines before and during zoledronate therapy.

Synergy
What is happening. Zoledronic acid rapidly suppresses bone resorption and can drive serum calcium down within days of infusion, especially in patients with low calcium intake, vitamin D deficiency, or impaired renal function. Adequate calcium intake is required by major osteoporosis guidelines before and during zoledronate therapy.
Mechanism. Zoledronate inhibits osteoclast FPPS, halting bone resorption and the calcium efflux from bone that normally helps maintain serum calcium. Adequate dietary calcium supplies the system from the gut instead, preventing hypocalcemia.
Recommendation. Take elemental calcium 1000-1200 mg/day from diet plus supplements (split 500 mg per dose) throughout zoledronate therapy. Ensure intake is adequate in the days immediately after each infusion. Because zoledronate is given intravenously, there is no oral-dose timing concern.
