We conducted a study to understand how vitamin D3 influences lung cancer, particularly focusing on a protein known as histidine-rich calcium-binding protein (HRC). Our research explored whether vitamin D3 could help lower HRC levels, given its crucial role in calcium balance, which is significant in cancer development.
We measured the expression of HRC and the vitamin D receptor (VDR) in lung cancer tissues compared to normal and adjacent non-cancerous tissues. Using various lab techniques, we assessed how vitamin D3 affects lung cancer cells, including their growth, spread, and ability to undergo programmed cell death, known as apoptosis.
Our findings revealed that vitamin D3 does inhibit the expression of HRC, which in turn decreased the migration and proliferation of lung cancer cells. Additionally, we noted an increase in the number of cells undergoing apoptosis in response to vitamin D3 treatment. In our animal model, mice treated with a vitamin D3 formulation exhibited smaller tumors and fewer cancerous cells than those treated with a combination of vitamin D3 and HRC.
Overall, our study indicates that vitamin D3 plays a protective role against lung cancer by downregulating HRC, thus slowing tumor growth and promoting cancer cell death.

Vitamin D helped me survive Stage 4 metastatic melanoma cancer. I’ve been taking this product for over nine years, and I owe my survival in part to raising my vitamin D levels to 180. At 75 years old, I appreciate the strength it has given me, as shown in the photos of before and after.
