Abstract

|
|
The purpose of this study was to compare the relative bioavailability of synthetic Vitamin C and Nutra-C¢ç (calcium ascorbate) using a randomized parallel pharmacokinetics study design. Under fasting conditions, 20 healthy volunteers were randomly allocated to receive a single oral dose (500 mg of ascorbic acid) of either synthetic Vitamin C or Nutra-C¢ç. Fasting blood was collected pre-dose and 1, 2, 3, 4, 7 and 10 hr post-dose. The ascorbic acid content of human serum was determined using HPLC with ultraviolet detection. The fasting serum ascorbic acid concentrations of synthetic Vitamin C and Nutra-C¢ç were 6.734 ¡¾ 2.09 ng/mL (n = 10) and 7.542 ¡¾ 2.96 ng/mL (n = 10), respectively. The bioavailability of Nutra-C¢ç was significantly greater (128 %, p < 0.05) than that of the synthetic Vitamin C.
