The association between B vitamins and the risk of COVID-19

This study was undertaken on 9189 adult participants of the Yazd Health Study (YaHS) and Taghzieh Mardom-e-Yazd (TAMIZ) study aged 20 to 69 years. Data on dietary intakes were obtained using a validated food frequency questionnaire (FFQ). Multivariable logistic regression analysis was used to evaluate the association between B vitamins and COVID-19. Our findings indicated that participants in the fourth quartile of vitamin B5 intake compared to the first quartile had a protective effect against COVID-19 (OR: 0. 53 CI: 0.28- 0.99, p- trend =0.02) after adjustment for all possible confounds in model 3. In addition, participants in the third quartile of vitamin B12 intake compared to the first quartile (OR: 0.63, 95% CI 0.40-0.98, P-trend= 0.11) had fewer odds of COVID-19 after full adjustments for confounders. Our findings indicated no significant relationship between dietary intake of vitamin B1, B2, B3, B9, and B-complex and COVID-19. A higher intake of vitamin B5 could reduce the odds of COVID-19 by 47%, and a moderate intake of vitamin B12 had a protective effect on COVID-19. Although our study has promising results, stronger clinical studies are needed.PMID:36348570 | DOI:10.1017/S0007114522003075
