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.

Lower risk for mortality, ICU admission, hospitalization, progression, recovery, cases, and viral clearance.

No treatment is 100% effective. Protocols combine complementary and synergistic treatments. ^* >10% efficacy in meta analysis with ≥3 clinical studies.

4,100+ studies for 60+ treatments. c19early.org

RCT 72 moderate COVID-19 patients with vitamin D deficiency or insufficiency in Indonesia, showing faster viral clearance and improved recovery with 10,000IU vitamin D vs. 1,000IU vitamin D. Higher vitamin D levels were associated with shorter length of stay (p = 0.009).

10,000IU vs. 1,000IU cholecalciferol daily for 2 weeks.

Cholecalciferol was used in this study. Meta analysis shows that late stage treatment with calcitriol / calcifediol (or paricalcitol, alfacalcidol, etc.) is more effective than cholecalciferol: 65% [41‑79%] lower risk vs. 39% [26‑49%] lower risk. Cholecalciferol requires two hydroxylation steps to become activated - first in the liver to calcifediol, then in the kidney to calcitriol. Calcitriol, paricalcitol, and alfacalcidol are active vitamin D analogs that do not require conversion. This allows them to have more rapid onset of action compared to cholecalciferol. The time delay for cholecalciferol to increase serum calcifediol levels can be 2-3 days, and the delay for converting calcifediol to active calcitriol can be up to 7 days.

Background & aims: Vitamin D supplementation as an immunomodulator has been identified as a potential strategy to prevent and treat Coronavirus disease 2019 (COVID-19). We aimed to analyze the effect of 10,000 IU vitamin D3 supplementation on 25(OH)D levels on primary clinical outcomes (conversion length), inflammatory markers (Total Lymphocyte Count (TLC), Neutrophil-to-Lymphocyte Ratio (NLR), Platelet-to-Lymphocyte Ratio (PLR)) and coagulation marker (D-Dimer

CONCLUSION The effects of 10,000 IU Vitamin D3 supplementation in moderate COVID-19 patients whom have low vitamin D status showed improvements in LOC, LOS, clinical manifestations, functional capacity, and positive correlation on inflammatory and coagulation markers, such as PLR.
