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.

We investigated the potential of vitamin D3, also known as cholecalciferol, in combating cancer while addressing concerns about its toxicity at higher doses. This study focused on enhancing the effectiveness of vitamin D3 through a clever method called liposomal encapsulation, which helps minimize side effects.
We prepared liposomal vitamin D3 (VD-LP) and conducted various tests to understand its capabilities. We found that this encapsulated form not only maintained high efficiency but also demonstrated improved stability. Our analyses showed that VD-LP had strong effects against cancer cells from colorectal, breast, and prostate cancers. Remarkably, it affected gene expression in immune cells, boosting elements that help fight infections and support the body's defenses.
Notably, VD-LP did a great job slowing tumor growth in mice and improved their survival rates without causing adverse effects like hypercalcemia, which is often a concern with regular vitamin D3 use. This evidence indicates that liposomal encapsulation of vitamin D3 could offer an effective cancer treatment strategy while minimizing unwanted side effects.
We believe this may pave the way for further research and clinical applications, showcasing vitamin D3 as a valuable addition to cancer therapy.

Best D-3 out there. The picture shows Melatonin not D-3, which is a mistake from either Life Extension or Amazon, but the product I received was correct: Vitamin D-3. Buying through Amazon incurs no tax and free shipping with Prime. This brand is recommended by a world-renowned cancer specialist as a supplement in the treatment of prostate cancer.

We explored how Vitamin D3 impacts autoimmune thyroiditis, a specific autoimmune disorder. In this study, researchers established a mouse model of experimental autoimmune thyroiditis (EAT) to see how Vitamin D3 could influence this condition. After eight weeks of treatment, they assessed thyroid health and immune response through various methods, including staining tissues and measuring hormone levels.
Our observations revealed that administering Vitamin D3 helped reduce damage to the thyroid and decreased the presence of inflammatory cells within the thyroid. This treatment also led to lower levels of thyroid hormones and autoimmune antibodies in the blood, highlighting its positive effect on thyroid function. Additionally, Vitamin D3 appeared to promote the regulatory T cell (Treg) subset while decreasing the levels of Th17 cells, which are often involved in autoimmune processes.
Mechanistically, the study found that Vitamin D3 triggered specific pathways that influence Treg cell activity and survival. Notably, it activated a signaling pathway involving YAP and JAK/STAT, which are crucial for immune cell regulation. These findings suggest that Vitamin D3 could play a significant role in balancing immune responses in autoimmune thyroiditis, making it a promising candidate for further research and potential treatment strategies.

This is my first order with iHerb, but I've been using these vitamins for two years, and they have proven effective for me. I'm now keen to order more since it's so easy (I previously lived in the Philippines, now residing in KSA). Thank you!

Since taking Vitamin D3 for two years, I no longer experience coughs, colds, or sniffles. Vitamin D3 aids the innate immune system and is distinct from Vitamin D (calcium).

We explored the impact of vitamin D3 levels on bone pain that patients experience after undergoing unicompartmental knee arthroplasty (UKA). The study involved 240 participants who were divided into three groups based on their vitamin D status—some received treatment before surgery, some after, and others had normal levels to begin with.
By administering vitamin D3 in three doses, we aimed to see if correcting deficiencies could alleviate post-operative bone pain. Throughout the recovery period, we measured pain levels using the visual analog scale at various intervals after the surgery.
Our findings clearly demonstrated that patients who corrected their vitamin D3 deficiency before surgery reported significantly better pain control after the operation compared to those who were treated afterwards or those who started with adequate levels. This highlights the importance of testing and addressing vitamin D status prior to orthopedic procedures, showing that it is a modifiable risk factor affecting recovery.

Truly AMAZING!!! I have been using this product and it has proven effective. My daughter had a breast cyst causing her bone pain for a few months, and her doctor advised surgery to remove it. Instead, I gave her 2 soft gels with each meal (totaling 6 soft gels a day). After 4 weeks, the pain was gone, and another 2 weeks later, the cyst had completely disappeared. A million thanks to Life Extension Vitamin D3. Now, my daughter is well.

We aimed to understand how vitamin D influences bone health and helps combat osteoporosis, a condition that weakens bones. In our study, we used various mouse models, including those that mimic a deficiency in active vitamin D. Through a range of advanced methods, we assessed how changes in vitamin D levels affected bone structure and metabolism.
The research revealed that insufficient vitamin D led to a drop in Sirt1, a gene that plays a crucial role in maintaining bone density. This lack of Sirt1 resulted in increased bone loss. However, when we boosted Sirt1 levels in bone stem cells, we observed a reversal in bone loss. This improvement happened because higher Sirt1 levels reduced oxidative stress, slowed down aging processes in bone cells, and enhanced new bone formation while curbing bone resorption.
Additionally, our findings indicated that vitamin D directly stimulates Sirt1 expression in these stem cells, which is vital for bone health. We also explored the effects of resveratrol, a natural compound known for activating Sirt1, and found it helped alleviate osteoporosis symptoms linked to vitamin D deficiency by enhancing the relationship between Sirt1 and another protein called PGC1α, which supports bone formation and energy metabolism.
This research underscores the importance of the vitamin D-Sirt1/PGC1α axis in bone metabolism, providing insight into how vitamin D can serve as a target for osteoporosis prevention and treatment.

I have been taking Vitamin D3 for a long time on my doctor's advice, to aid calcium absorption for Osteoporosis. I never exceed 1000IU and have tried many brands. This product is very good, with small capsules that have no aftertaste, indicating excellent quality.
