Low Heavy Metal Calcium

ESC® obliterates California Prop 65 and USP requirements for heavy metal levels.

Overview

ESC® brand calcium from eggshells is a naturally pure calcium source compliant with FDA, USP, and California Proposition 65 limits for heavy metals at the full 1,000 mg dose of elemental calcium per day. ESC is highly absorbable – its matrix consists of an ultra-pure form of calcium carbonate with high elemental calcium content, inherent transport proteins to help facilitate calcium absorption, and many trace minerals which the body needs to maintain healthy bone health.* This translates into a superior source of calcium over other bone health ingredients.

Quality

ESC® is ultra pure and is 50-times lower than California Prop 65 heavy metal limits for lead at 100% of the daily value for calcium.  ESC is manufactured in the USA within FDA-inspected, NSF-certified GMP facilities using an environmentally friendly patented manufacturing process. Every lot of ESC undergoes "release" testing which includes; verifying it is low in toxic heavy metals and ensuring it is free from pathogenic bacteria. Our attention to detail and passion for assisting our finished product partners in creating high quality, effective products can be seen within every step of our commercialization process.

ESC® brand eggshell calcium is one of nature’s purest forms of calcium. ESC® naturally combines ultra-pure calcium carbonate with inherent transport proteins for maximum absorption and essential trace minerals for supporting bone health.* The high elemental calcium (minimum 35%) allows for a smaller dose and greater formulation flexibility.  ESC® is sustainably sourced from a renewable supply of US-domestic eggshells. This remarkable form of calcium is available in original ESC® and ESC® ORGANIC!
