Ester-C Calcium Ascorbate
Ester-C® is a unique and patented form of Calcium Ascorbate-Threonate. It is made using a proprietary, water-based manufacturing process which results in a pH neutral product that contains naturally occurring vitamin C metabolites.
Ester-C Calcium Ascorbate-Threonate is the only form of vitamin C, with research validating retention in white blood cells. A clinical study (available on request) showed that Ester-C® increased vitamin C levels in the body for up to 24 hours.
The main benefits of Ester-C® are its quick absorption, 24-hour retention in the immune system, and neutral pH which makes the product gentle to the stomach.
Ester-C® is listed on the Annex 2 list of 1924/2006 Food Supplements Directive (EFSA Journal 2009; 7 (9): 1226). All the EFSA Claims on Vitamin C can be used for Ester-C, alongside the other benefits and advantages of this patented product.
Ester-C® Calcium Ascorbate-Threonate is produced in USA exclusively by The Ester C Company, part of the NBTY Inc family of companies, and distributed exclusively in Europe by Gee Lawson Ltd (with the exception of Germany and Scandinavia).
