The typical daily dosage recommendations for calcium magnesium zinc nutrients are:
- Calcium: 1,000 mg — 100% of the Daily Value (DV)
- Magnesium: 400–500 mg — 100–125% of the DV
- Zinc: 15–50 mg — 136–455% of the DV
To reach these amounts, you would need to take 2–3 calcium-magnesium-zinc supplements over the course of the day.
The variations in dosage — and that of zinc in particular — owes to the fact that these minerals come in numerous formulations.
For example, zinc is available in several forms, each of which contains different amounts of elemental zinc — the kind that your body can use. Thus, calcium magnesium zinc supplements that list a high dose of this mineral tend to contain forms that provide less elemental zinc.

Because of concerns for long-term adverse side effects, including calcification of arteries and kidney stones, both the U.S. Institute of Medicine (IOM) and the European Food Safety Authority (EFSA) set Tolerable Upper Intake Levels (ULs) for combined dietary and supplemental calcium.
From the IOM, people of ages 9–18 years are not to exceed 3 g/day combined intake; for ages 19–50, not to exceed 2.5 g/day; for ages 51 and older, not to exceed 2 g/day. EFSA set the UL for all adults at 2.5 g/day but decided the information for children and adolescents was not sufficient to determine ULs.
Calcium is a common constituent of multivitamin dietary supplements, but the composition of calcium complexes in supplements may affect its bioavailability which varies by the solubility of the salt involved: calcium citrate, malate, and lactate are highly bioavailable, while the oxalate is less.
Other calcium preparations include calcium carbonate, calcium citrate malate, and calcium gluconate. The intestine absorbs about one-third of calcium eaten as the free ion, and the plasma calcium level is then regulated by the kidneys.
An adult body has 22–26 grams of magnesium, with 60% in the skeleton, 39% intracellular (20% in skeletal muscle), and 1% extracellular. Serum levels are typically 0.7–1.0 mmol/L or 1.8–2.4 mEq/L. Serum magnesium levels may be normal even when intracellular magnesium is deficient.
The mechanisms for maintaining the magnesium level in the serum are varying gastrointestinal absorption and renal excretion. Intracellular magnesium is correlated with intracellular potassium. Increased magnesium lowers calcium and can either prevent hypercalcemia or cause hypocalcemia depending on the initial level.
