Ester-C® is different from ordinary or buffered vitamin C because it is processed in purified water instead of solvents which makes it a purer form of vitamin C. It contains calcium threonate, making this form of vitamin C four times more bioavailable than other forms of vitamin C.

Vitamin C is an important antioxidant and free radical scavenger. Free radicals are incomplete atoms or molecules that are the natural by-products of everyday metabolic, detoxification, and immune system processes. These unstable compounds attack nearby molecules in an attempt to become complete. Antioxidants like vitamin C are the body’s natural defense system against free radicals. Antioxidants are molecules that can safely neutralize these harmful substances helping to promote cell health and support against cellular damage that could lead to disease.
