Ultra Anti-Oxidant, provided by Douglas
Laboratories, is a potent antioxidant dietary
supplement that includes not only antioxidant
vitamins such as ascorbate and d-alpha tocopheryl
succinate, but also other nutrients that effectively
participate in our body’s antioxidant defense systems.
Body cells and tissues are threatened continuously by
damage caused by toxic free radicals and reactive
oxygen species (e.g., peroxides) which are produced
during normal oxygen metabolism, by other chemical
reactions, and by toxic agents in the environment. Free
radicals, once formed, are capable of disrupting
metabolic activity and cell structure. When this occurs,
additional free radicals are produced which, in turn, can
result in more extensive damage to cells and tissues.
The uncontrolled production of free radicals is thought
to be a major contributing factor to many degenerative
The body’s antioxidant defense system is more than the
sum of its parts. That’s because antioxidants depend on
each other for ongoing effectiveness. For example,
beta-carotene supports vitamin E, recognized as the
body’s most valuable fat soluble antioxidant. It
prevents oxidation of unsaturated fatty acids by
inactivating free radicals, thus stabilizing and
protecting cell membranes, e.g. in the lungs, eyes, and
arteries. Vitamin E can be regenerated by vitamin C.
Vitamin C is a potent water-soluble antioxidant
nutrient, also protecting cells from oxygen free radical
damage. It is essential for connective tissue and bone
metabolism, capillary health, and immune function.
Vitamin C works together with vitamin E. When
vitamin E is inactivated by neutralizing free radicals,
vitamin C regenerates it back to full activity. In this
process, however, vitamin C is oxidized and loses its
antioxidant activity. Glutathione reactivates vitamin C,
while selenium and B-vitamins are needed to keep
Glutathione is a naturally occurring tripeptide which is
a major component of two anti-free radical enzymes -
glutathione peroxidase and glutathione reductase. As
such, glutathione offers one mechanism for scavenging
toxic free radicals and inhibiting peroxidation thereby
slowing down free-radical catalyzed chain reactions.
Glutathione can also reactivate (reduce) oxidized
vitamin C. Glutathione per se is well absorbed in the
intestine, and enters the blood and other extracellular
compartments where it exerts much of its beneficial
antioxidant effects. However, it can not effectively
enter the cell.
N-Acetylcysteine is a precursor for the sulfur amino
acid cysteine which is used by the cells to synthesize
glutathione. In contrast to glutathione, N-acetylcysteine
is efficiently transported into the cell where it is readily
converted to cysteine for glutathione synthesis. Thus,
supplementation with N-acetylcysteine is recognized as
a safe, highly effective method of increasing
intracellular glutathione stores. Aside from providing
cysteine as a glutathione precursor, N-acetylcysteine
also appears to have antioxidant properties as such, and
is a valuable sulfur donor for various metabolic needs.
The bioflavonoids of Ultra Anti-Oxidant, i.e. rutin,
heseridin, and Pycnogenol?, provide additional
antioxidant power, while zinc is needed to maintain the
activity of the antioxidant enzyme superoxide dismutase.
Adults take 1 capsule 3 times daily with meals or as
directed by physician.
