Rx Vitamins for Pets Bio C for Dogs and Cats
Pure Sodium Ascorbate with Bioflavonoids
Bio-C is a palatable, easy-to-administer powdered source of supplemental vitamin C combined with bioflavonoids. Sodium ascorbate has a saltier, less sour taste than ascorbic acid and is a potent, water soluble antioxidant. This form of vitamin C is naturally buffered and thus reduces gastric distress commonly associated with high doses of straight ascorbic acid. Bioflavonoids increase the absorption and utilization of vitamin C.
Formulated By Robert J. Silver, D.v.m., M.s.

To provide a palatable, easy to administer powdered source
of supplemental vitamin C combined with added bioflavonoids
to be used as a potent water-soluble anti-oxidant for all
species of animal.
THERAPEUTIC STRATEGY of this FORMULA:
1) Anti-oxidant properties protect from aqueous-base free
2) Immune system benefits
3) Address chronic diseases that are caused by or worsened
by conditions of oxidative stress (Diabetes, cataracts,
arthritis, cancer, allergies, asthma and other respiratory
diseases, immune system problems)
INGREDIENT LIST (1 level scoop [1/8th tsp] contains):
1. Vitamin C (as sodium ascorbate).................................................................500
2. Lemon bioflavonoid complex (24% flavones).....................................................20
Vitamin C as Sodium Ascorbate:
Sodium ascorbate is the sodium ester of ascorbic acid. Most
companion animals find it palatable when added to their
meals. It has a saltier, less sour taste than ascorbic acid,
and a less bitter taste than calcium ascorbate and other
mineral ascorbates. It is less likely to cause the bowel
distress commonly associated with high doses of ascorbic
Vitamin C was first isolated from bovine adrenal cortex
in 1928 by the Hungarian biochemist, Albert Szent-Gyorgyi,
and was later found, in 1932 in lemon juice. As a result
of this extract's ability to counteract the effects of scurvy,
which is the deficiency syndrome of vitamin C, it was initially
named the "antiscorbutic factor" or hexuronic
acid, based on the fact that chemically it is a hexose derivative.
Vitamin C deficiency results in the symptom-complex deficiency
disease called "scurvy", whose symptom picture
includes: Inflamed and bleeding gums, petechiae, ecchymoses,
follicular hyperkeratosis, perifollicular hemorrhages, impaired
wound healing, dry eyes and mouth (Sjogren's syndrome),
arthralgia, joint effusions, muscle weakness, myalgia, fatigue,
depression, frequent infections, anemia, anorexia, diarrhea,
and pulmonary and kidney problems than can lead to coma
and death. (17)
In the 73 years since its discovery, research into the effects
of vitamin C has discovered quite a number of biological
activities for this valuable vitamin: They include the following:
1. Co-factor in the carnitine biosynthetic pathway (13)
2. Modulates iron absorption, transport and storage (13)
3. Involved in the biosynthesis of corticosteroids, aldosterone,
the conversion of cholesterol to bile acids (13)
4. Functions as a reducing agent for mixed-function oxidases
(reactive oxygen and nitrogen species) (13)
5. Involved in the biosynthesis of collagen, elastin, fibronectin,
proteoglycans, bone matrix, and elastin-associated fibrillin
6. Plays a role in collagen gene expression and cellular
procollagen secretion (13)
7. Anti-oxidant properties: Ascorbate spares and regenerates
the major lipid anti-oxidant d alpha-tocopherol (vitamin
E) from the alpha tocopheroxyl radical form. Vitamin c also
preserves intracellular reduced glutathione concentrations.
8. Plays a role in the prevention of cancer by assisting
in the detoxification of carcinogens, as well as blocking
the carcinogenic process via its antioxidant properties
9. Anti-hypertensive activity and role in the prevention
of coronary heart disease, has been demonstrated by increasing
the synthesis of prostaglandin PGE1 and other eicosanoids
that also possess anti-thrombotic and vasodilatory activity,
also helps to maintain nitric oxide levels by preserving
intracellular glutathione levels, and spares nitric oxide
by its scavenging of superoxide radicals. Nitric oxide also
exerts a vasodilatory effect. (21)
10. Immunomodulatory activity due to enhancement of neutrophils
chemotaxis, and an anti-histaminic effect. It also can enhance
lymphocyte proliferation secondary to mitogen stimulation
and natural killer cell activity. (12)
11. Reduces age-related lens opacification or cataracts
due to oxidative stress. (20)
12. Benefits respiratory mucosa against irritants, allergens,
viral infection and asthma, due, in part to its anti-oxidant
13. Heavy metal toxicity and chemical toxicity effects are
reduced due to vitamin C's anti-oxidant and chelating activity.
Vitamin C is important in the formation and maintenance
of collagen and other tissues. It is needed for the fibrin
matrix formation and wound healing. Mature cartilage and
connective tissue cells do not contain significant amounts
of vitamin C, however, they are the first cells to be affected
by vitamin C deficiencies and disease. Dogs with hepatic
dysfunction have lowered plasma concentrations of ascorbic
Vitamin C is a part of the glutathione peroxidase pathway
for repairing oxidative damage to the lipid cell membrane.
Most animals (except the guinea pig and a few others) produce
their own vitamin C by synthesizing it form glucose in the
liver. However, when the immune system is in a weakened
state it will not produce enough vitamin C to maintain homeostasis.
Supplementation with exogenous vitamin C can help the animal
stay in balance.

Lemon Bioflavonoids (standardized to 24% flavones)
Bioflavonoids have anti-oxidant properties. (3) They are
found to be present along with vitamin C in citrus fruit,
localized in highest concentrations in the white portion
of the peel of the fruit.
These bioflavonoid preparations contain, rutin, hesperidin
In a controlled study, researchers found that 35% more vitamin
C was absorbed when it was given with a citrus bioflavonoid
extract than when vitamin C was given alone. (3)
The majority of studies into the effects of bioflavonoids
were carried out on a standardized mixture of rutin, known
as hydroxyethylrutosides (HER). Substantial clinical benefit
was observed in the treatment of capillary fragility, easy
bruising, hemorrhoids and varicose veins with HER. (2) Lemon
bioflavonoids posses similar but not as potent effects as
Increase absorption of vitamin C (3)
Help in the formation of collagen cross-linkages (14)
Anti-microbial effect due to influence on cell permeability
Lower cholesterol (11)
Anti-inflammatory activity (5)
Anti-cataract activity due to inhibition of cataract-forming
Anti-histaminic effect due to inhibition of mast cell histamine
Bioflavonoids work synergistically with vitamin C, based
upon the work of the discoverer of vitamin C, Albert Szent-Gyorgyi,
who isolated these compounds from citrus fruits and Hungarian
paprika. Szent-Gyorgyi believed that the bioflavonoids work
together with vitamin C to maintain blood capillary health,
and in the prevention of capillary fragility. (8) They have
been shown in studies to protect the vascular endothelium
from free radical damage. (4).
One in vitro study demonstrated the synergistic interaction
between vitamin C and the flavonoid quercitin in protecting
cutaneous skin cells from the oxidative damage induced by
a glutathione deficiency. (18)
