Design outcomes

Primary

MeasureTime frame
To assess the comparative bioavailability of Investigational products (Liposomal Vitamin C and Normal Vitamin C) and to understand the effect of the manufacturing process on the bioavailability of Vitamin C in normal healthy adult human subjects under fasting conditions.Timepoint: -01.00, -00.50 and 00.00 (within15 minutes) hours prior to dosing and the post dose blood samples will be collected at 00.50, 01.00, 01.50, 02.00, 02.50, 03.00, 03.50, 04.00, 04.50, 05.00, 05.50, 06.00, 07.00, 08.00, 10.00, 12.00 and 24.00 hours.

Secondary

MeasureTime frame
To monitor the safety and tolerability of a single oral dose administered in Healthy, Adult, Human Subjects Under Fasting Conditions.Timepoint: Medical Examination will be done during screening, at the time of check-in and check-out. Vitals monitoring will be done at screening, check-in, check-out, drug administration and at 01.00, 03.00, 06.00 and 12.00 hours post dose. Post Study safety sample will collected to assess the safety of subjects at the end of the study.
