Purpose
This comprehensive study examines the multifaceted relationship between vitamin D and cancer, synthesizing key scientific advancements and global research trends to guide future investigations and address critical gaps in the field.
Methods
Publications on vitamin D and cancer were retrieved from Scopus up to November 2024. English-language original and review articles were analyzed using Excel, VOSviewer, and Scimago Graphica, focusing on publication trends, citation impacts, and research themes.
Results
A total of 11,442 publications (80.01% original articles, 19.98% reviews; 51.24% open access) were analyzed. The United States of America led in publications (38.3%) and citations (56.2%), followed by China (7.7%) and the United Kingdom (7.2%) in output, and the United Kingdom (10.6%) and Germany (6.4%) in citations. Countries with the highest citations per document were Belgium (103.4), Slovenia (87.9), and Puerto Rico (76.6).
The most frequently studied cancers in relation to vitamin D were
breast,
colorectal,
prostate,
skin,
lung,
ovarian,
pancreatic,
gastric,
hepatocellular,
thyroid,
leukemia,
multiple myeloma,
bladder,
lymphoma,
osteosarcoma,
cervical,
endometrial, and
glioblastoma, respectively.
Cluster analysis revealed key patterns related to vitamin D:
Calcitriol’s chemopreventive role in breast, prostate, and colorectal cancers,
dietary vitamin D for its involvement in ovarian cancer,
vitamin D for regulation of cancer-related hypercalcemia,
vitamin D deficiency links to inflammation-obesity-cancer risk,
VDR polymorphisms affecting outcomes in lung and colorectal cancers, and
vitamin D’s photoprotective effects on skin malignancies, and
vitamin D in ulcerative colitis-related cancer.
The most cited articles emphasized optimal vitamin D levels and cancer prevention.
Conclusion
This study highlights the extensive research on vitamin D and its complex links to cancer, emphasizing future prospects with a focus on precision medicine approaches, including targeted supplementation and genomic analyses, to better address individual variability in cancer prevention and treatment.

Vitamin D Cancer trials often fail due to any of 5 reasons
Gave too small of dose
Gave same size dose to everyone
- more is needed by obese, dark skinned, elderly, poor health, poor gut, etc.
Got most participants above 30 ng level of vitamin D
- but some Cancers, like Breast, are known to need >80 ng
Trial lasted only months instead of years - Cancers take many years to develop
Trial only measured blood levels - 6 genes restrict how much Vitamin D gets to the Cancer cells
Trial only used Vitamin D monotherapy
often need co-factors, such as Omega-3 or Magnesium to boost the reponse to Vitamin D
while also fighting inflammation
