Adjunctive Nutraceutical Therapies for COVID-19

Area of Science:

• * Nutritional Science and Immunology
• * Infectious Diseases and Public Health

Background:

• * The severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) pandemic poses a global health threat, affecting all age groups.
• * While many experience mild symptoms, older adults, immunocompromised individuals, and those with comorbidities face severe risks.
• * Historically, nutraceuticals have served as adjunct therapies for various conditions, including viral infections.

Purpose of the Study:

• * To comprehensively review the potential therapeutic and prophylactic roles of nutraceuticals against SARS-CoV-2/COVID-19.
• * To explore the efficacy of specific vitamins, minerals, and phytochemicals as adjunct treatments.

Main Methods:

• * Literature review of existing studies on nutraceuticals and viral infections.
• * Analysis of scientific evidence regarding the antiviral properties of selected supplements.
• * Synthesis of data on vitamins C, D, E, zinc, melatonin, and other phytochemicals.

Main Results:

• * Evidence suggests certain nutraceuticals possess antiviral, anti-inflammatory, and immunomodulatory properties.
• * Vitamins C, D, E, zinc, and melatonin show promise in potentially mitigating SARS-CoV-2 infection severity.
• * Phytochemicals and functional foods are also highlighted for their potential contributions.

Conclusions:

• * Nutraceuticals may offer beneficial adjunct therapeutic and prophylactic strategies for COVID-19.
• * Further research is warranted to establish optimal dosages and clinical efficacy.
• * These natural compounds represent a potential avenue for supporting public health initiatives against the pandemic.
