Vitamin D counteracts blood clottingVitamin D Inhibits IL-6 Pro-Atherothrombotic Effects in Human Endothelial Cells: A Potential Mechanism for Protection against COVID-19 Infection?
High relevance to blood clotting
Our research focused on understanding how Vitamin D (VitD) might influence blood clotting, especially in the context of COVID-19. We found that when human endothelial cells were exposed to IL-6—an inflammatory cytokine associated with severe COVID-19—it led to dysfunction in these cells. This dysfunction was marked by increased levels of Tissue Factor (TF) and cell adhesion molecules (CAMs), which promote blood clotting.
Remarkably, when we treated these endothelial cells with VitD, we observed a reversal of these harmful effects. VitD appeared to inhibit the expression of TF and CAMs and even modulated the levels of the ACE2 receptor, which is crucial for the entry of the virus into cells. Our findings suggest that VitD could play a protective role against the blood clotting complications associated with COVID-19 by counteracting IL-6's effects on endothelial cells.
Overall, this study paves the way for further research into VitD as a potential therapeutic option for mitigating thrombotic risks in COVID-19 patients.

Vitamin D linked to clot riskRelationship of Serum 25-Hydroxyvitamin D Concentrations, Diabetes, Vitamin D Receptor Gene Polymorphisms and Incident Venous Thromboembolism.
Study shows vitamin D relevance
We set out to understand how levels of vitamin D, specifically serum 25-hydroxyvitamin D (25OHD), influence the risk of developing venous thromboembolism (VTE), which includes serious conditions like deep vein thrombosis and pulmonary embolism. To do this, we examined a large cohort of nearly 378,000 participants, all free from VTE at the start of the study.
Our analysis focused on the relationship between vitamin D levels and VTE risk, particularly in individuals with diabetes compared to those without. Over a median follow-up period of 12.5 years, we recorded just over 10,600 new cases of VTE.
The findings were quite revealing: higher serum 25OHD concentrations were associated with a lower risk of VTE. This inverse relationship was especially pronounced in participants with diabetes. Interestingly, while we assessed various genetic factors that could influence VTE risk, they did not significantly change how vitamin D affected the likelihood of developing a blood clot.
However, we did find that specific genetic variations in the vitamin D receptor appeared to enhance the protective effects of vitamin D against VTE. Overall, we are encouraged by our findings, which suggest that maintaining sufficient levels of vitamin D may help reduce the risk of blood clots, particularly in those already managing diabetes.

Vitamin D mitigates platelet aggregation1,25-Dihydroxyvitamin D3 attenuates platelet aggregation potentiated by SARS-CoV-2 spike protein via inhibiting integrin αIIbβ3 outside-in signaling.
Relevant findings on COVID-19 impact.
We explored how 1,25-Dihydroxyvitamin D3, a form of vitamin D, can influence platelet aggregation, particularly in the context of COVID-19. Platelet hyperreactivity is a condition where platelets are overly reactive, contributing to blood clotting issues often seen in COVID-19 patients. Our investigation focused on how vitamin D might help mitigate these issues by examining its direct effects in the laboratory.
We found that vitamin D significantly reduced platelet aggregation, especially when this aggregation was heightened by the SARS-CoV-2 spike protein. This effect appears to be linked to vitamin D's ability to inhibit certain signaling pathways involved in platelet activation. Notably, the treatment reduced the activation of integrin αIIbβ3, which plays a key role in platelet spreading and clumping.
By utilizing a particular Src family kinase inhibitor, we confirmed that there are overlapping pathways being influenced, as both vitamin D and the inhibitor showed similar effects in lowering platelet responses. Our findings suggest that vitamin D could serve as a beneficial treatment to help manage clotting in COVID-19, though further exploration is necessary.

Vitamin D's role in blood clotsThe Association between Vitamin D Levels and Thrombus Burden in Patients with ST-Elevation Myocardial Infarction.
Essential link in thrombus burden
We sought to understand how vitamin D levels might impact thrombus burden—essentially the amount of blood clotting—specifically in patients suffering from ST-elevation myocardial infarction (STEMI) who are about to undergo primary percutaneous coronary intervention (PCI), a common procedure to restore blood flow to the heart.
Our research involved 257 STEMI patients who were observed in a hospital setting over a year. We divided these patients into two groups: those with high thrombus burden and those with low thrombus burden. After looking at various factors, one clear finding emerged: patients with high thrombus burden had significantly lower vitamin D levels compared to those with low thrombus burden. In fact, the average vitamin D levels in patients with high thrombus burden were only 8.0 ng/mL compared to 17.9 ng/mL in those with low thrombus burden.
We also discovered that patients with high thrombus burden and low vitamin D levels had poorer outcomes post-PCI, including decreased blood flow and lower heart performance. Through further analysis, we found vitamin D levels were an independent predictor of thrombus burden. Those with levels above 17.6 ng/mL showed an impressive 81.8% sensitivity for predicting low thrombus burden.
Overall, our study indicates that maintaining adequate vitamin D levels could play a significant role in reducing the risks associated with blood clotting in heart attack patients undergoing critical interventions.

Vitamin D linked to blood clotsRelationship between vitamin D deficiency and thrombus load in patients with ST-elevation myocardial infarction.
Significant correlation found
We explored the connection between vitamin D deficiency and the burden of blood clots in patients experiencing ST-elevation myocardial infarction (STEMI). In this study, we evaluated 77 patients, measuring their serum vitamin D levels alongside the amount of coronary thrombus they had, which was quantified using the Thrombolysis in Myocardial Infarction (TIMI) frame count.
Our findings revealed that a staggering 79% of the participants had low vitamin D levels, defined as less than 20 ng/mL. Interestingly, those with mild thrombus loads showed higher vitamin D levels compared to those with severe loads, suggesting some influence of vitamin D on thrombus formation. Additionally, we found a consistent negative correlation between lower vitamin D levels and higher thrombus burden.
Even though the study highlights a clear association between low vitamin D levels and increased thrombus load, it doesn't specifically test vitamin D treatment to see if it can reduce this risk. Essentially, while low vitamin D appears to predict higher thrombus formation, we do not have evidence from this study that boosting vitamin D levels directly helps prevent clots in this patient group.

Works well - my blood test numbers improved significantly within two months, indicating that it absorbs well. I recommend it to anyone seeking a good vitamin D supplement.
Best! It rapidly restored my blood vitamin D levels.
I had a severe increase in blood vitamin content after the course. The raw vitamins didn't seem effective.
NO. It raised my blood sugar levels.
