Outcome Measures
Primary Outcomes (6)
vitamin c detection
vitamin c was assessed by Ascorbic Acid Colorimetric Assay Kit II
at 8 hours after taking test sample
The change of Triglyceride
Venous blood was sampled to measure concentrations of Triglyceride
at 8 hours after taking test sample
The change of body mass index (BMI)
BMI is a measurement of a person's leanness or corpulence based on their height and weight, and is intended to quantify tissue mass.The body mass index (BMI, kg/m\^2) and body mass (kg) were assessed by InBody770.
Time 0, 0.5, 1, 2, 3, 4, and 8 hours after taking test sample
The change of aspartate aminotransferase
Venous blood was sampled to measure concentrations of aspartate aminotransferase
at 8 hours after taking test sample
The change of alanine aminotransferase
Venous blood was sampled to measure concentrations of alanine aminotransferase
at 8 hours after taking test sample
The change of creatine
Venous blood was sampled to measure concentrations of creatine
at 8 hours after taking test sample
