1 Improving Vitamin D Status in the Management of COVID-19

A novel coronavirus disease 2019 (COVID-19) outbreak is a global dramatic pandemic that is immeasurably impacting the communities. Due to lack of data, symptomatic management is used for COVID-19 infection including oxygen therapy and mechanical ventilation for those with severe infection. Considering immunomodulatory, anti-inflammatory anti-fibrotic and anti-oxidant actions of vitamin D, it's safety and ease of administration, as well as direct effects of vitamin D on immune cell proliferation and activity, pulmonary ACE2 expression and reducing surface tension, evaluation of vitamin D supplementation as an adjuvant therapeutic intervention could be of substantial clinical and economic significance. High prevalence of vitamin D deficiency in elderly, smokers, patients with chronic diseases and excess uptake by adipose tissue in obesity make investigations of its role as a secondary therapeutic agent in COVID-19 conceivable. It should be necessary to monitor serum 25(OH)D levels in all inpatient and outpatient populations with COVID-19 to identify the importance of maintaining or promptly increasing circulating levels of 25(OH)D into the optimal range of 100-150 nmol/L. The aim of this study is to conduct a double blind, randomized, controlled three weeks clinical trial on the efficacy of vitamin D (daily low dose versus weekly high dose) in COVID-19 patients in order to determine the relationship between baseline vitamin D deficiency and clinical characteristics and to asses patients' response to vitamin D supplementation in week three and determine its association with disease progression and recovery. Subjects who are randomized to high-dose will be asked to take 50,000 IU for two times during the first week and one dose over second and third weeks to quickly raise their serum levels. Subjects in the low-dose arm will take vitamin D 1000 IU daily for three weeks.

2 Therapies to Prevent Progression of COVID-19, Including Hydroxychloroquine, Azithromycin, Zinc, Vitamin D, Vitamin B12 With or Without Vitamin C, a Multi-centre, International, Randomized Trial: The International ALLIANCE Study

COVID-19 is a global pandemic. So far encouraging results have been shown in different parts of the world with the utilisation of hydroxycloroquine, zinc, and azithromycin, and early studies into some of these, plus some with Vitamin C, have also proven beneficial. Vitamin D levels have also been shown to be an important indicator to the severity of symptoms in COVID-19 patients.

3 Randomized Double-Blind Placebo-Controlled Proof-of-Concept Trial of Resveratrol for the Outpatient Treatment of Mild Coronavirus Disease (COVID-19)

There is evidence that resveratrol might help fight coronavirus as well as help protect the body from the effects of disease (COVID-19) caused by the infection. In this proof-of-concept pilot study we will compare the effects of resveratrol to placebo to assess the safety of resveratrol and explore effectiveness.

4 Vitamin D Testing and Treatment for Adults With COVID 19

This study will measure vitamin D levels in adults with COVID 19. Participants with low levels of vitamin D will be entered into an open label trial of supplementation with vitamin D.
