Vitamin D Could Prevent 30,000 Cancer Deaths Per Year in Germany Alone
Modern cancer policy is dominated by expensive drugs, marginal survival gains, and soaring end-of-life costs. Yet quietly, a low-cost and widely accessible intervention has been sitting in plain sight.
A peer-reviewed analysis published in Molecular Oncology examined what would happen if adults aged 50 and older received routine vitamin D supplementation at modest daily doses. The results are deeply inconvenient for a system built around high-cost treatment rather than prevention.
Using national mortality data and randomized controlled trial meta-analyses, researchers estimated that daily vitamin D supplementation could:
- Prevent ~30,000 cancer deaths per year in Germany alone
- Save ~322,000 life-years annually
- Reduce overall cancer mortality by ~13%, consistent across multiple RCT meta-analyses
- Lower total healthcare spending, even after accounting for the cost of supplementation
Annual supplementation costs (~$1.0 billion per year) were outweighed by reductions in end-of-life cancer care, producing net savings of ~$280 million annually.
For context, many modern oncology drugs cost tens of thousands of dollars per patient while extending survival by weeks or months. By contrast, vitamin D supplementation:
- Costs ~$11–$55 per person per year
- Demonstrates actual mortality reduction
- Remains highly cost-effective even under worst-case assumptions
Even when researchers ignored all cancer-care cost savings, the cost per life-year saved was approximately $3,100 — far below standard cost-effectiveness thresholds used to justify new cancer drugs.
Yet despite widespread deficiency, routine vitamin D supplementation remains absent from most cancer-prevention strategies — while healthcare systems continue to pour resources into late-stage treatment with diminishing returns.
Cancers Vitamin D Has Shown Benefit Against
Beyond population-level mortality reductions, a large and growing body of mechanistic, clinical, and translational evidence shows vitamin D activity across multiple cancer types. A 2023 peer-reviewed synthesis of over 900 recent studies highlights consistent anti-cancer effects mediated through vitamin D receptor (VDR) signaling, immune modulation, and tumor microenvironment control.
.Vitamin D has demonstrated protective or therapeutic effects in:
- Breast cancer (including triple-negative subtypes)
- Prostate cancer
- Colorectal cancer
- Ovarian cancer
- Glioblastoma (brain cancer)
- Melanoma
- Squamous cell carcinoma (skin and head & neck)
- Head and neck cancers
- Bladder cancer
- Non-small cell lung cancer
- Multiple myeloma
- Osteosarcoma (bone cancer)
Across these cancers, vitamin D has been shown to:
- Suppress tumor growth and proliferation
- Induce apoptosis and ferroptosis
- Inhibit metastasis and epithelial-to-mesenchymal transition (EMT)
- Improve response to chemotherapy and immunotherapy
- Reduce treatment resistance
- Improve survival in deficient patients
Importantly, low vitamin D status is repeatedly associated with worse prognosis, more aggressive disease, and reduced survival — while adequate levels or supplementation are linked to improved outcomes.
Some of the most powerful cancer-prevention tools are neither novel nor profitable.
Vitamin D is inexpensive. It is biologically active across immune, inflammatory, and cellular regulatory pathways. And according to randomized trial evidence, it saves lives — at scale.
The only real question left is why public health policy continues to ignore it.

I don’t think you need supplementation either.
– Get out in the sun with as much skin exposed as possible.
– Eat foods rich in Vitamin D (cod liver oil, mushrooms exposed to the sun, etc).
– Fasting can help too.

Sun? It’s January, what’s that?
The sun is great, for half the year, but for those of us in northern latitudes, that provides nothing during the other half of the year. Suppliments are required.
