That’s Calcium Ascorbate for you, the star of our exclusive Ester‑C® formula. Ester-C® was discovered back in the early 80s, when its inventor, an ever-curious doctor and scientist, set out on a quest for the first stomach-friendly Vitamin C. After much research, Ester-C® would come to be known as “The Better Vitamin C®” for its superior support of the immune system.

Long Lasting Immune Support

We’re Long-Lasting, For Up To 24 Hours*

Clinical studies show Ester-C® increasing vitamin C levels in white blood cells, an essential part of the immune system. Translation: Ester-C® stays in your system longer than regular vitamin C, as in up to 24 hours. The naturally occurring metabolites in our formula, teeny tiny molecules that run your metabolism, are the reason why our C can last from sunrise to sunrise.

Stomach Friendly

WE’RE EASY TO STOMACH*

Ester-C® is designed to be nonacidic, meaning that it has a neutral pH. In a recent clinical trial, people who are generally sensitive to acidic foods were given either Ester-C® or ascorbic acid. Needless to say, the results prove that Ester-C® is easier on the stomach.
