Vitamin D Supplementation and Cancer

 

This article will focus on Vitamin D supplementation and cancer.

For decades, vitamin D has been considered an essential vitamin for supporting the immune system, general well-being, and also mental health.

This information developed over time when patients with low vitmain D presented with a wide array of health concerns. To mention a few, usually patients with low vitamin D are prone to repeated infections such as colds/flu. They usually describe these flu episodes as being  not only frequent but also longer-lasting, and they are usually resistant to the supportive care.

Low vitamin D is linked to lower energy, and those affected struggle with daily tasks and often feel physically and mentally exhausted.

 

It wasn't until a few decades ago that many scientists and medical oncologists discovered the link between Low Vitamin D and cancer prognosis, and they found that there is a correlation between Low Vitamin D and advanced cancer presentations and even cancer mortality.

 

In 2022, a group of scientists studied the impact of vitamin D supplementation/optimization and the activation of vitamin D receptors in the body (called VDR), which leads to gene activation. These genes control various bodily functions such as energy regulation, immune system support, and bone formation. One of the interesting gene pathways modulated by vitamin D receptors (VDR) is those linked to cellular differentiation, which means that they are essential to help cell differentiation and growth.

In cancer biology, one of the most important observations is the lack of cellular differentiation that signals the initiation of cancer cells and/or propagation or spread.

So, these scientists concluded that vitamin D optimization is an important factor in the battle against cancer that helps with the differentiation of cancer cells. The link to this article is here https://pubmed.ncbi.nlm.nih.gov/34411566/
