Magnesium citrate helps the body absorb calcium and supports healthy bone density, while vitamin D3 helps the body absorb calcium and phosphorus and supports healthy immune function. Vitamin K2 helps transport calcium to the appropriate areas in the body, such as the bones and teeth, and may also support cardiovascular health.
