Ester-C® is the brand name for Vitamin C in Calcium Ascorbate form along with small amounts of the vitamin C metabolites dehydroascorbic acid (oxidized ascorbic acid), calcium threonate, and trace levels of xylonate and lyxonate. Although the company that makes Ester-C® claims its Vitamin C is more bioavailable than other commercially available Vitamin C supplements, a claim based on an unpublished study, a small, published study found no differences between Ester-C® and commercially available ascorbic acid supplements with regard to absorption. However, the fact still remains that the source of Vitamin C in Ester-C® is synthetic and likely made using genetically modified organisms.
In view of the foregoing, the best form of Vitamin C may be one that is sourced from an organic, food source naturally rich in Vitamin C and bioflavanoids and without any of the risks inherent in genetically modified, synthetic forms of Vitamin C.
