Ester-CŪ is a patented form of Vitamin C. It provides 24-hour immune support, is non-acidic, and contains naturally-occurring metabolites for quick absorption.* Ester-CŪ is the most patented Vitamin C brand in the world and, since its benefits are supported by science, you know you are giving your body the advanced immune support it shouldn't be without.*

24-Hour Immune Support

A recent clinical study showed that Ester-CŪ increased vitamin C levels in the body for up to 24 hours.1 White blood cell levels of Vitamin C were elevated in subjects receiving Ester-CŪ when measured 24 hours after initial dose. The presence of key metabolites such as threonate have been shown to be responsible for this increased level and retention of Vitamin C by the cells. No other patented vitamin C brand can make this claim!

Naturally-Occurring Metabolites For Quick Absorption *

During the Ester-CŪ patented manufacturing process, vitamin C metabolites are created. These naturally-occurring metabolites activate the vitamin C molecules in Ester-CŪ, making it easier and quicker for the body to transport them from cell to cell for numerous health benefits.*

Non-Acidic and Gentle on the Stomach

n a recently published study, individuals sensitive to acidic foods were given 1 gram of vitamin C as ascorbic acid or as Ester-CŪ. Subjects reported heartburn “significantly more frequent and severe after intake of ascorbic acid” and subjects rated Ester-CŪ as tolerated “very good” significantly more than ascorbic acid.2 So for anyone who has difficulty tolerating vitamin C, it is comforting to know that Ester-CŪ has been clinically shown to be non-acidic and gentle on the stomach.

Ester-CŪ functions biologically like other forms of Vitamin C, providing strong antioxidant support against free radical damage, healthy skin, joint and vision support, cardiovascular wellness and maintenance of the immune system.* However, Ester-CŪ offers so much more...quick absorption by the body and 24-hour retention in the immune system.* Plus, since it is non-acidic, Ester-CŪ is gentler on the digestive system, even when taken at high doses.*
