Superior Bioactivity

with Vitamin K Krebs Cycle Calcium complex

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

Ultra-Cal Night is specifically designed to be taken at night. 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.

Ultra-Cal Night contains a 1:1 ratio of calcium and magnesium, along with other bone minerals such as copper, manganese and zinc, and soy isoflavones to provide support for bones.

Contains: No yeast, dairy, egg, sugar, starch, salt, preservatives, or artificial color, flavor or fragrance.
