International and national official surveys and publications have documented dietary deficiencies that may have deleterious repercussions to immunomodulation. Brazilian population that sought spontaneously for D Vitamin pre and post the since the Covid 19 pandemia was specially studied using databases collected throughout Brazil. The number of people that sought for their D vitamin levels were three times bigger during the pandemia. The mean D vitamin levels were significantly lower in the pandemic period as compared to the pre pandemic. Of the total of 1,421 tests performed in the observed period, 25.2% were performed in 2019 (prepandemic) and 74.8% were performed in 2020 or 2021 (pandemic). Most of the individuals tested were women over 20 years of age. The proportion of individuals over 60 years was higher in 2020-2021, compared to 2019 (12% vs. 39.5%). There was no significant difference in D vitamin mean between cohorts by gender, age or region. These results point to the awareness of having to live a healthy nutritional lifestyle and even follow guidance for supplementation.
