*BEST BEFORE 08/19* Vitamin C - Crystal C 400mg 90 Tablets *DISCONTINUED*

The Benefits of Crystal C™ - Why is it the better Vitamin C.
Fully Reacted - non-acidic, neutral pH

Sodium molecule used for reaction has been shown to enhance entry into the cells

Sodium molecule binds to the ascorbate molecule stronger than any other cations including calcium

Contains our special Riboperine™ Metabolites which have been shown to enhance the uptake of Vitamin C. Unlike Ester type products which only contain 1% metabolite, Crystal C™ contains 5% metabolites

Completely, 100% water soluble as a powder

Reduces/eliminates intestinal upset

A powerful Vitamin C that "enters" the body and cells, the EnterCell™ Technology, through multiple pathways, MULTI-PATH™

Crystal C™ with Riboperine™ Metabolites goes beyond Vitamin C, goes beyond an Ester and does more than either one could ever do!

Each 400mg coated tablet of Crystal C™ contains 334mg of Vitamin C (555% RDA*). 

Oral Absorption Study Of Vitamin C Supplements
( A Preliminary Report )

1. Purpose:
To determine the plasma total ascorbate levels after oral gavage of Ascorbic acid, Ester C and Crystal C at a dose of 8 mgs/kg body weight as equivalent ascorbate activity.

2. Results:
The mean Total Ascobate plasma concentrations ( micrograms/ml ) are given below:

The data are graphically presented in the shown chart.

3. Discussion of results:
The data shows, at equal ascorbate activity, administered as Ascorbic acid, Ester C or Crystal C, Crystal C attained the highest plasma level at 30 minutes post dose. Compared to Ester C, Crystal C attained a 41% higher plasma level at 30 minutes. Crystal C plasma levels were 414% higher than Ascorbic acid at 30 minutes while Ester C was only 260% higher. At 60 minutes Crystal C was 71%, and at 90 minutes, 160 % higher than the corresponding plasma levels attained with Ester C. At 60 and 90 minutes the plasma ascorbate concentrations from Ester C fell below both Crystal C and Ascorbic acid.

The fourth point on each respective curve represents the result of regression analysis. Ester C plasma levels return to baseline ( control ) levels approximately 105 minutes post dose. Extrapolation predicts that Ascorbic acid plasma levels return to baseline at 120 minutes and Crystal C approximately 180 minutes post dose.

The AUC ( area under the curve ) for Crystal C is in the range of 175% greater than Ester C and 200% greater than Ascorbic acid plasma levels.

The AUC is a measure of Total Ascorbate activity delivered and thereby absorbed over the test period.

4. Conclusions:
At equal ascobate activity doses Crystal C attains higher ascorbate plasma levels than Ester C or Ascorbic acid. These higher levels are maintained for the entire test period. Crystal C delivers 175% more ascorbate activity than maintained by an equal ascorbate activity dose of Ester C. The maintenance of plasma levels by Crystal C is due to a more rapid and sustained oral uptake than Ester C or Ascorbic acid. This is based on the fact that the down slopes of of the plasma levels are at the same rate until return to baseline.
