IV Vitamin C (Sodium Ascorbate): 30g /day for 4 days;
equivalent to 50mg/kg every 6hrs on day 1 followed by 100mg/kg every 6hrs (4x day, 400mg/kg/day) for 4 days (average 28g/day; maximum dose of 50g/24hrs for those weighing more than 125kg).

Safety/efficacy
Statistical methods / analysis
Sample size calculation
The minimum sample size required is N=100 in each intervention arm in order to have 80% statistical power to detect a 30% relative risk reduction (RRR) in the proportion progressing to mechanical ventilation or death, assuming a standard-of-care risk of progression of 30%. Since participants will be hospitalized, we assumed minimal (<1%) loss to follow-up.

Statistical analysis methods
The primary analysis of efficacy will be conducted under the intention-to-treat principle; all randomized participants will be included in the analyses. All results will be analyzed with 2-sided level of significance of 0.05. Continuous variables will be analysed by Student-t test and repeated measures ANOVA, and categorical variables will be analysed by Chi-Square test. Subgroup analyses by gender, BMI, vaccination status, vitamin D levels will be explored.

Summary
Brief summary
Stage 2 of this study is linked to Stage 1 - ACTRN12620000557932

COVID-19 is a global pandemic.
So far encouraging results have been shown in different parts of the world with the utilisation of quercetin, zinc, and intravenous Vitamin C. Vitamin D levels have also been shown to be an important indicator to the severity of symptoms in COVID-19 patients. This study aims to find the optimal treatment protocol for hospitals to consider in their treatment of COVID-19 patients and their endeavours to save lives.
