An Ultra-pure Calcium Ingredient

Bone strength is a crucial aspect of our pets' health throughout their life.
Overview

ESC® brand calcium from eggshells is a naturally pure calcium source (with extremely low heavy metals) that 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 are beneficial in maintaining healthy bone mineral density.* This translates into a superior source of calcium over other bone health ingredients.
Quality

ESC® is an ultra-refined, food-sourced eggshell calcium nearly 20% more absorbable than other forms of calcium carbonate that helps support bone health.* ESC® is also 50-times lower than California Prop 65 heavy metal limits for lead at 100% DV calcium (human DV). ESC offers high elemental calcium (35%) allowing for smaller dose size and greater formulation flexibility than many calcium sources. It is sustainably sourced from a renewable supply of US-domestic eggshells. ESC® is manufactured in the USA within FDA-inspected, NSF-certified GMP facilities using an environmentally friendly patented manufacturing process.

  • Sustainably sourced from US-domestic eggshells
  • Safe (GRAS), Non-GMO
  • Made in the USA
  • Certified Kosher and Halal

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!
