Could Getting More Sunshine Vitamin Be a Secret to Beating Bladder Cancer?

Bladder cancer may not frequently make headlines, but it’s a deadly disease that claims more American lives annually than car accidents. The good news is that researchers in Spain have discovered a vitamin that can significantly reduce your risk of developing bladder cancer – vitamin D.

After analyzing blood tests from over 2,000 people, the scientists found that having high levels of vitamin D in your body considerably diminishes your chances of getting bladder cancer.

Vitamin D and Bladder Cancer

According to researcher Núria Malats, “those subjects with the highest levels of 25(OH)D3, a stable form of vitamin D in the blood, are those who showed the lowest risk of suffering bladder cancer. These results indicate that high levels of this vitamin are associated with protection from the illness or, similarly, that low levels are associated with a higher risk of suffering from it.”

The study demonstrates that vitamin D aids the body in limiting the production of certain proteins that would otherwise promote cancer. Researcher Francisco X. Real explains, “we have also shown, using in vitro molecular analysis, that vitamin D regulates the expression of a protein — FGFR3 — that takes part in the development of bladder cancer.”

How Vitamin D Helps Prevent Cancer

Vitamin D is essential for maintaining a healthy body, as it helps the body absorb calcium, which in turn builds and maintains strong bones. Many people get this vitamin from natural sunlight, while others acquire it through their diet or supplements.

But vitamin D also plays other roles in our bodies. It has anti-inflammatory properties, helps maintain a strong immune system, and works to regulate cell growth and function. These attributes help combat the development and progression of cancer, particularly bladder cancer. In fact, several studies have indicated a link between higher vitamin D levels and lower risk of various types of cancer, such as breast, prostate, and colon cancer.

How to Increase Your Vitamin D Levels

Although some might think the best way to increase vitamin D levels is through sun exposure, this isn’t always the case. Experts recommend that people limit their exposure to sunlight to reduce the risk of skin cancer. That said, there are alternatives that can help boost your vitamin D levels.


Certain foods are rich sources of vitamin D. These include:

  • Fatty fish such as salmon, mackerel, tuna, and sardines
  • Cod liver oil
  • Beef liver
  • Cheese
  • Egg yolks
  • Fortified milk, orange juice, and cereals


The recommended daily allowance (RDA) of vitamin D differs depending on your age. According to the National Institutes of Health Office of Dietary Supplements, the RDA for vitamin D is:

  • 0-12 months: 400 IU (10 mcg)
  • 1-70 years: 600 IU (15 mcg)
  • 71 years and older: 800 IU (20 mcg)

It’s important to consult with your doctor before taking vitamin D supplements, as taking too much can lead to toxicity or other adverse health effects.


Regular physical activity has been shown to increase vitamin D levels in the body. Make sure to incorporate moderate-to-vigorous exercise for at least 30 minutes daily to potentially boost your vitamin D levels.

The Importance of Regular Screening

It’s crucial to regularly monitor your vitamin D levels, especially if you’re at a heightened risk of developing bladder cancer or other forms of the disease. This can easily be done through a simple blood test. Regular screenings can also help detect cancer in its early stages, increasing the chances of successful treatment and recovery.

Bladder cancer affects millions of people worldwide and can be a deadly disease if not detected and treated early. By maintaining optimal levels of vitamin D and staying informed of the latest research and prevention methods, you can significantly reduce your risk of developing this life-threatening illness.
