A quiet routine many people barely think about—getting enough vitamins—might hold more influence over serious illness than expected.
For those navigating cancer treatment, even small daily habits can feel like they carry enormous weight.
According to research from São Paulo State University, funded by Fundação de Amparo à Pesquisa do Estado de São Paulo (FAPESP), scientists are now looking closely at something surprisingly simple, reports Science Daily.
A simple addition
In a clinical study involving 80 women over 45, researchers tested whether adding vitamin D to chemotherapy could make a measurable difference.

Participants were divided into two groups, with one receiving a daily supplement while the other took a placebo.
All patients underwent chemotherapy before surgery, a standard approach aimed at shrinking tumors.
After six months, the group receiving vitamin D showed notably stronger outcomes. A significantly higher proportion experienced complete disappearance of detectable cancer compared to those without supplementation.
Why it matters
Vitamin D is commonly associated with bone strength, but its role in immune defense is gaining attention.

Many cancer patients begin treatment with low levels of the vitamin, which may influence how the body responds to therapy.
Researchers highlighted several possible advantages:
- Supports immune system activity
- May enhance response to treatment
- Widely available and low-cost
This positions vitamin D as a potentially accessible support tool, especially compared to more expensive medical interventions.
Still early days
Despite promising results, scientists emphasize that the study was relatively small. Larger trials are needed to confirm how much impact vitamin D truly has on chemotherapy effectiveness and whether results apply broadly.

The findings suggest potential—but not certainty. For now, experts see this as a starting point rather than a finished solution.
