Vitamin D for COVID-19
8th treatment shown to reduce risk in October 2020
 
*, now known with p < 0.00000000001 from 120 studies, recognized in 8 countries.
No treatment is 100% effective. Protocols combine complementary and synergistic treatments. * >10% efficacy in meta analysis with ≥3 clinical studies.

Retrospective 47 patients in Indonesia showing lower vitamin D levels associated with increased COVID-19 symptoms. Adjusted results are only provided for vitamin D levels as a continuous value.
This is the 170th of 196 COVID-19 sufficiency studies for vitamin D, which collectively show higher levels reduce risk with p<0.0000000001 (1 in 11,637 vigintillion).
risk of symptomatic case, 70.6% lower, RR 0.29, p < 0.001, high D levels (≥10ng/ml) 10 of 34 (29.4%), low D levels (<10ng/ml) 13 of 13 (100.0%), NNT 1.4.
risk of symptomatic case, 45.6% lower, RR 0.54, p = 0.42, high D levels (≥20ng/ml) 2 of 7 (28.6%), low D levels (<20ng/ml) 21 of 40 (52.5%), NNT 4.2.
Effect extraction follows pre-specified rules prioritizing more serious outcomes. Submit updates

Background: Recently, there have been studies reporting a relationship between vitamin D levels in the blood and the immune system. This study aimed to analyze the association between vitamin D levels and symptoms of coronavirus disease 2019 (COVID-19). Materials and methods: This study was an analytical survey study with a cross-sectional approach, with lecturers at Universitas Malahayati that have been infected with COVID-19 in 2022 as subjects. Total 47 subjects were included. Subjects were fasted overnight, then blood samples were taken from subjects in the next morning. The blood was centrifuged, then the serum was separated for examination by the direct competitive chemiluminescence immunoassay (CLIA) method using Architect 25-OH Vitamin D Reagent. Data was analyzed using logistic regression. Results: None of the subjects had normal blood levels of 25(OH)D 3 and almost half (48.9%) of the subjects had symptoms when infected with COVID-19. There was a significant relationship between the level of 25(OH)D 3 (p=0.001) and the status of the COVID-19 vaccine (p=0.013) with the presence of symptoms in COVID-19 patients. Conclusion: The lower the level of 25(OH)D 3 in the blood and the more incomplete the COVID-19 vaccine, the greater the onset potential of COVID-19 symptoms. It is necessary to maintain vitamin D intake and increase the coverage of the COVID-19 vaccine, especially at booster doses.
