    ESC® Whole-Food Calcium

    ESC® is one of nature’s purest and most absorbable forms of calcium from eggshells. ESC® combines ultra-pure calcium carbonate with inherent transport proteins for maximum absorption and essential trace minerals to support normal bone mineral density.* ESC® is the whole-food choice for BONE HEALTH.

    ESC® Calcium is a unique, source of calcium. ESC®’s high elemental calcium (allowing for a smaller dose), and superior bioavailability provide distinct advantages for supporting bone health.*

    • Transporter proteins in eggshell calcium significantly enhance bioavailability.
    • Multiple human clinical trials have shown the effectiveness of eggshell calcium for bone mineral density support.*
    • High elemental calcium (minimum 35%) provides greater formulation flexibility.
    • Ultra-Pure ESC® is lower in Heavy Metals than other calcium sources.
    • Non-chemical, eco-friendly manufacturing process in an FDA regulated GMP facility.
    • Ultra-refined eggshell calcium avoids typical digestive discomfort.
    • Provides a pure source of calcium that appeals to the growing consumer demand.

    The Purity Difference - Key Co-Factors*

    Vitamin D - without Vitamin D, Calcium can’t be adequately metabolized. Vitamin D is an important regulator of calcium metabolism and supports bone health by maintaining calcium balance. Vitamin D is crucial for cellular differentiation and it maintains healthy cellular function throughout the body.*

    Magnesium – a cofactor for hundreds of essential metabolic processes in the body.*

    Vitamin K - is included in the formula to promote optimum delivery of calcium into bones and help maintain normal levels of calcium in soft tissues.*

    Ultra-Pure Calcium™ features an emerging super star ingredient spotlighted in the media called Vitamin K2. Vitamin K2’s function in the body is crucial in that it enhances calcium absorption into the bones and helps KEEP Calcium in the bones, where it belongs. By virtue of this, Vitamin K2 keeps Calcium out of other areas of the body, where we do not want it to accumulate.*

    Along with a well-balanced diet, Ultra-Pure Calcium helps maintain healthy bone mass over time.*
