Abstract |
This specially formulated tablet provide a gradual release of 1000 mg of vitamin C over a prolonged period of 12 hrs. This action prolongs benefits by maintaining a constant level of vitamin C in the blood.
This gradual and prolonged bioavailabilty of vitamin C makes it available
to your body whenever it is needed and as a powerful anti-oxidant it is often
needed. We take one in the morning and one at night for 24 hour
bioavailabilty.
Normally when you take a vitamin C tablet it quickly flows through the body
and is passed in urine. Mostly it is wasted and cannot do it duty when it
is not available. It makes a lot of sense to use a time (or sustained)
released product. We think that this product is the answer to that
problem.
C-1000 capsules are easier to swallow and assimilate. No tablet binders, coatings or colorings. They are free of the most common allergens such as corn, soy, yeast, barley, wheat, lactose, (milk sugar) and all milk, citrus, fish and egg products. No added flavorings, sugars, salt, artificial sweeteners, colorings, preservatives or salicylates

Blood levels and bioavailability of ascorbic acid (Vitamin C) after administration of a sustained-release formulation to humans.
Sacharin R, Taylor T, Chasseaud LF.
Plasma and whole blood concentrations of ascorbate (Vitamin C) have been measured after administration of 1000 mg of the vitamin as standard or sustained-release capsule formulations to human subjects. A peak of mean whole blood and plasma concentrations of 8.5 mug/ml and 5.7 mug/ml respectively (corrected for predose concentrations of "endogenous"
ascorbate (Vitamin C)) occurred at 12 hours and 6 hours respectively after administration of a sustained-release formulation. After administration of a standard formulation, the peak of mean whole blood and plasma concentrations of 9.4 mug/ml and 8.6 mug/ml respectively occurred at 4
hours. In whole blood, mean concentrations of ascorbate (Vitamin C) declined with a half-life of about 34 h.
The bioavailability of ascorbate (Vitamin C) from the sustained-release formulation was 149% and 180% of that from the standard formulation by calculation from whole blood and plasma concentration data respectively.
