Brief Summary:
The purpose of this study is to investigate the therapeutic benefits of flavonoids nutritional supplements quercetin and curcumin for early mild symptoms of COVID-19.

Condition or disease Intervention/treatment Phase
COVID-19 Drug: Standard of care Dietary Supplement: Investigational treatment Not Applicable

Detailed Description:

Flavonoids nutritional supplements quercetin and curcumin have demonstrated strong antioxidant, broad-spectrum anti-viral and anti-inflammatory properties including against the respiratory tract infections. They are widely used to boost the immunity against infections and keeping healthy life-style. Results from recent published studies have shown positive results for quercetin and curcumin in patients with COVID-19.

In the present study the investigators aim to study the combined beneficial effects of quercetin and curcumin in addition to standard of care for managing early mild symptoms of COVID-19 in community-based patients.
