USANA MagneCal D
A balanced magnesium and calcium supplement fortified with vitamin D to support bone health and more.


The entire skeletal structure constantly remodels itself, and in 10 years, you’ll have a completely new skeleton. This remodeling process requires sufficient amounts of magnesium, calcium, and vitamin D from the diet to form the bones properly.*

The body stores a significant amount of dietary magnesium and calcium in bones and can pull nutrients from them to support a multitude of physiological functions. But if our bodies consistently use more calcium and magnesium than is replaced, it may lead to bone loss.

Vitamin D also plays many important roles in the body, including supporting proper mineral absorption for bone health. In fact, all three of these nutrients work as co-factors, each playing a role in the proper utilization of the others.*

USANA’s MagneCal D can help you get sufficient amounts of magnesium, calcium, and vitamin D every day to help in the maintenance of your bones and teeth.*


The nutrients in MagneCal D support cell-signaling and help provide a nutritional foundation for the activities and pathways targeted by USANA® products made with InCelligence Technology™.*

Higher intakes of magnesium have been associated with higher levels of bone mineral density.* Additionally, magnesium is a co-factor in more than 300 enzyme systems that control various natural reactions in the body, including:

  • Protein, DNA, and RNA synthesis
  • Normal nerve transmission
  • Neuromuscular conduction and muscular contraction
  • Healthy glucose metabolism

Many of these benefits contribute to magnesium’s support for cardiovascular health. Research has also shown that magnesium can help support healthy or normal arterial elasticity.*

Adequate vitamin D and calcium, as part of a healthy diet, along with physical activity, may reduce the risk of osteoporosis in later life. Vitamin D aids calcium and phosphorus absorption and utilization. Without sufficient vitamin D, bones can become thin, brittle, or misshapen.*

In addition to supporting strong bones and teeth, the body uses calcium to support many processes, including healthy blood clotting, cell division, and more.*

MagneCal D also contains silicon and boron. Silicon gives stability to connective tissues and is essential for proper calcium utilization. Boron reduces calcium excretion and increases deposition of calcium in the bone.*


MagneCal D offers a balanced ratio of calcium to magnesium plus advanced amounts of vitamin D. It is carefully formulated for excellent absorption to give you the best support for healthy bones.*
