Vitamin D for COVID-19
8th treatment shown to reduce risk in October 2020, now with p < 0.00000000001 from 125 studies, recognized in 9 countries.
No treatment is 100% effective. Protocols combine treatments.
5,300+ studies for 116 treatments. c19early.org
In Vitro study showing that calcitriol minimizes platelet aggregation mediated by SARS-CoV-2 spike protein via inhibiting integrin αIIbβ3 outside-in signaling. Authors find that calcitriol reduces platelet aggregation and Src-mediated signaling induced by the spike protein. Specifically, calcitriol attenuated spike protein-enhanced platelet spreading and the phosphorylation of β3, c-Src, and Syk. Using the Src family kinase inhibitor PP2, authors confirmed that the combination with calcitriol did not show additive inhibitory effects, suggesting that calcitriol operates through the same pathway.
25 preclinical studies support the efficacy of vitamin D for COVID-19:
Vitamin D has been identified by the European Food Safety Authority (EFSA) as having sufficient evidence for a causal relationship between intake and optimal immune system function24-27. Vitamin D inhibits SARS-CoV-2 replication in vitro14,21, mitigates lung inflammation, damage, and lethality in mice with an MHV-3 model for β-CoV respiratory infections14,21, reduces SARS-CoV-2 replication in nasal epithelial cells via increased type I interferon expression17, downregulates proinflammatory cytokines IL-1β and TNF-α in SARS-CoV-2 spike protein-stimulated cells13, attenuates nucleocapsid protein-induced hyperinflammation by inactivating the NLRP3 inflammasome through the VDR-BRCC3 signaling pathway18, may be neuroprotective by protecting the blood-brain barrier, reducing neuroinflammation, and via immunomodulatory effects28, may mitigate hyperinflammation and cytokine storm by upregulating TLR10 expression which downregulates proinflammatory cytokines10, downregulates ACE2 and TMPRSS2 in human trophoblasts and minimizes spike protein-induced inflammation16, may minimize cytokine storm by dampening excessive cytokine production1, minimizes platelet aggregation mediated by SARS-CoV-2 spike protein via inhibiting integrin αIIbβ3 outside-in signaling12, and improves regulatory immune cell levels and control of proinflammatory cytokines in severe COVID-1929. Calcifediol inhibits SARS-CoV-2 papain-like protease (PLpro), a critical enzyme for viral replication11. Symptomatic COVID-19 is associated with a lower frequency of natural killer (NK) cells and vitamin D has been shown to improve NK cell activity30,31.

It has been demonstrated that Vitamin D deficiency is associated with the severity of COVID‐19 infection.

In this study, we investigated the direct effects and underlying mechanisms of 1,25(OH)<jats:sub>2</jats:sub>D<jats:sub>3</jats:sub> on platelet hyperreactivity induced by SRAS‐CoV‐2 spike protein via Western blot and platelet functional studies in vitro.

We further observed that 1,25(OH)<jats:sub>2</jats:sub>D<jats:sub>3</jats:sub> attenuated spike protein‐potentiated platelet aggregation in vitro.
