ESC® (EggShell Calcium) featured in Membrell’s BONEhealth, is one of nature’s purest and most absorbable forms of calcium and has been clinically proven to increase bone density.  ESC® naturally combines calcium carbonate with inherent transport proteins for maximum absorption and essential trace minerals for increasing bone mineral density.

Heavy metals in dietary supplements have been highly regulated by the government due to their detrimental impact on human health.  ESC® was tested down to parts per billion levels for lead, mercury, arsenic and cadmium. 

Results:  Findings concluded that ESC® is California Prop 65 compliant in all four heavy metals tested at the full daily value for calcium of 1,000 mg per day.  Lead levels in ESC® were more than 50 times lower than the California Prop 65 standard and more than 1,000 times lower than USP (United States Pharmacopeia) limit for Nutritional Supplements. The remaining metals of mercury, arsenic and cadmium were 50 to 450 times lower than the California Prop 65 standard levels.  Given ESC®’s enhanced bioavailability and clinical support with California Proposition 65 compliance, the result is the ideal natural calcium source.
