Contains soy.

Ultra-Cal Night is a scientifically advanced calcium formula, providing optimal forms of calcium and key co-nutrients to help support a healthy skeletal system.

Additional Information

Superior bioactivity

Krebs cycle calcium complex

Most of the minerals are bound to organic compounds of the Krebs cycle (cellular energy production system), allowing for optimal absorption and utilization.

Research indicates that food eaten during the day usually maintains adequate calcium levels in the blood. Taking calcium supplements at night offers added protection until breakfast.
