ESC® is one of nature’s purest and most absorbable forms of calcium and comes from a natural, sustainable source – eggshells. ESC naturally combines ultra-pure calcium with inherent transport proteins for maximum absorption and essential trace minerals for increased bone building support. ESC’s high elemental calcium (allowing for a smaller dose), and superior bioavailability provide distinct advantages over other bone health ingredients. Multiple clinical trials on eggshell calcium show effectiveness in supporting bone mineral density, some in as little as 4-8 months.

ESC® provides many trace minerals, such as strontium, zinc, phosphorus and boron further supporting bone mineral density. ESC naturally has extremely low levels of heavy metals – 50-100 times lower than Prop 65 and USP limits when tested at 100% DV.

ESC® is a whole-food source of calcium ideal for use in bone health supplements and any product desiring to increase calcium levels. ESC is manufactured by Stratum Nutrition’s joint venture partner, ESM Technologies, LLC in FDA-inspected cGMP facilities with an eco-friendly patented process in  FDA inspected cGMP facilities. It’s 100% natural, renewable and sustainable, which appeals to the growing consumer demand for natural products. US-domestic – Kosher and Halal Certified.
