Ester-C® 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-C® is the most patented Vitamin C brand in the world and,
since its benefits are supported by science, you know you are giving your
24-Hour Immune Support
body the advanced immune support it shouldn't be without.*
A recent clinical study showed that Ester-C® 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-C® 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-C® patented manufacturing process, vitamin C metabolites are
created. These naturally-occurring metabolites activate the vitamin C molecules
in Ester-C®, 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
In a recently published study, individuals sensitive to acidic foods were
given 1 gram of vitamin C as ascorbic acid or as Ester-C®. Subjects reported
heartburn “significantly more frequent and severe after intake of ascorbic acid”
and subjects rated Ester-C® 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-C® has been clinically shown to be
non-acidic and gentle on the stomach.
Why Take Ester-C®?
Ester-C® 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-C® offers so much more...quick absorption by the body and 24-hour
retention in the immune system.* Plus, since it is non-acidic, Ester-C® is
gentler on the digestive system, even when taken at high doses.*
