Amni® Ester-C® Complex capsules, provided by Douglas
Laboratories®, contain a non-acidic, calcium ascorbate form
of vitamin C combined with a potent citrus bioflavonoid
Ester-C® is a unique form of vitamin C that is created
through a patented, water-based process that combines
vitamin C and calcium. Ester-C® is non-acidic and should be
well-tolerated by those who are sensitive to the acidic nature
of ascorbic acid.
Vitamin C: Vitamin C (ascorbic acid) has numerous
biological functions. It is essential for the synthesis of
collagen and glycosaminoglycans, which are the building
materials of all connective tissues, such as skin, blood
vessels, tendons, joint cartilage and bone. Vitamin C is the
required coenzyme for two groups of enzymes that catalyze
the crosslinking of collagen fibers - lysyl hydroxylases and
prolyl hydroxylases. As such, vitamin C is essential for
normal wound healing and capillary health.
Vitamin C participates in the biosynthesis of carnitine,
serotonin, and certain neurotransmitters, including
Vitamin C is among the most powerful antioxidants in
humans and animals. It is a water-soluble, chain-breaking
antioxidant that reacts directly with superoxide, hydroxyl
radicals, and singlet oxygen. Laboratory studies show that
vitamin C completely protects lipids in plasma and lowdensity
lipoprotein (LDL) against atherogenic peroxidative
damage. In addition, vitamin C interacts with glutathione
and alpha-lipoic acid, and regenerates vitamin E.
The antioxidant functions of vitamin C appear to have
clinical significance in providing protection from free radical
damage to the eyes, lungs, blood and the immune system.
Vitamin C is absorbed in the small intestine by a sodiumdependent
transport process that is intake dependent. At
normal dietary intakes of 60 to 100 mg, up to 80 or 90% of
the vitamin C is absorbed. At higher intakes, absorption
becomes less efficient. Absorption efficiency and vitamin C
utilization may be greatly enhanced during conditions of
physiological stress, such as trauma or infection. Maximal
absorption is attained by the ingestion of several doses
spaced throughout the day rather than in one, larger dose.
Citrus Bioflavonoids. The white layer of citrus peels is
especially rich in the bitter tasting flavanones hesperidin and
naringin. Citrus juices, however, are low in bioflavonoids.
Like most flavonoids, those from citrus are free radical
scavenging antioxidants that work in synergy with vitamin
C. Ester-C® Complex provides 100 mg of a concentrated
bioflavonoid complex containing 35 mg hesperidin and 14
mg naringin. This extract is essentially free of citric acid to
which some people may be sensitive.
Gelatin, cellulose, water, and magnesium stearate.
1 to 2 capsules daily or as directed by physician.
The ingredients in Ester-C® Complex are well-tolerated and
do not generally cause side effects.
