While public health measures, vaccine development, and new therapeutics have made great strides in understanding and managing the pandemic, there has been an increasing focus on the potential roles of diet and supplementation in disease prevention and adjuvant treatment. In the literature, the impact of nutrition on other respiratory illnesses, including the common cold, pneumonia, and influenza, has been widely demonstrated in both animal and human models. However, there is much less research on the impact related to COVID-19. The present study discusses the potential uses of diets, vitamins, and supplements, including the Mediterranean diet, glutathione, zinc, and traditional Chinese medicine, in the prevention of infection and severe illness. The evidence demonstrating the efficacy of diet supplementation on infection risk, disease duration, severity, and recovery is mixed and inconsistent. More clinical trials are necessary in order to clearly demonstrate the contribution of nutrition and to guide potential therapeutic protocols.<\/jats:p>","DOI":"10.3390\/nu14091909","type":"journal-article","created":{"date-parts":[[2022,5,2]],"date-time":"2022-05-02T07:08:58Z","timestamp":1651475338000},"page":"1909","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":17,"title":["Do Diet and Dietary Supplements Mitigate Clinical Outcomes in COVID-19?"],"prefix":"10.3390","volume":"14","author":[{"given":"Bhavdeep","family":"Singh","sequence":"first","affiliation":[{"name":"Department of Basic Medical Sciences, College of Osteopathic Medicine, Western University of Health Sciences, Pomona, CA 91766, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Eli","family":"Eshaghian","sequence":"additional","affiliation":[{"name":"Department of Basic Medical Sciences, College of Osteopathic Medicine, Western University of Health Sciences, Pomona, CA 91766, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-6108-7304","authenticated-orcid":false,"given":"Judith","family":"Chuang","sequence":"additional","affiliation":[{"name":"Department of Basic Medical Sciences, College of Osteopathic Medicine, Western University of Health Sciences, Pomona, CA 91766, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Mihai","family":"Covasa","sequence":"additional","affiliation":[{"name":"Department of Basic Medical Sciences, College of Osteopathic Medicine, Western University of Health Sciences, Pomona, CA 91766, USA"},{"name":"Department of Biomedical Sciences, College of Medicine and Biological Sciences, University of Suceava, 7200229 Suceava, Romania"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2022,5,2]]},"reference":[{"key":"ref_1","unstructured":"Cascella, M., Rajnik, M., Aleem, A., Dulebohn, S.C., and Di Napoli, R.
