Avaliação laboratorial da Vitamina D antes e durante a pandemia de COVID-19 em indivíduos na Amazônia Brasileira

During the pandemic, vitamin D was widely consumed as a prevention strategy against COVID-19 due to its role in immunity. However, this practice has increased cases of hypervitaminosis D and toxicity, especially in the elderly, who are more likelyto use supplements to strengthen the immune system. This study analyzes vitamin D levels in individuals in the Brazilian Amazon before and during the COVID-19 pandemic, observing variation in levels due to increased supplementation or reduction by the recommended isolation aimed at reducing transmission of SARS-COV2. A retrospective study was carried out, based on a database from a laboratory medicine unit in Belém-PA, in two periods: before the pandemic, data recorded until 2019, and during the pandemic, data from 2020-2023. The research compared vitamin D levels between different age groups and gender, observing a significant increase in values above the safe limit in people aged 60 and over, a group that showed a greater tendency to toxicity. The resultshighlight the need for strict monitoring and medical guidance when using supplements, highlighting the potential adverse impact of prolonged self-medication.
