What the latest study suggests
Rising skin cancer rates have prompted researchers to look beyond sunscreen and shade into how lifestyle and nutrition might influence risk. A September 2025 study published in JAMA Dermatology analyzed health data from more than 33,800 veterans to examine whether a specific supplement could reduce the incidence of skin cancer. Participants were divided into two groups: one received the supplement at a dose of 500 mg twice daily, and a control group did not receive the supplement. The researchers focused on the two most common forms of skin cancer: basal cell carcinoma (BCC) and cutaneous squamous cell carcinoma (cSCC).
Study at a glance
The analysis looked for associations between supplement use and cancer occurrence over time. In this large, real-world dataset, the group taking the supplement showed a lower incidence of both BCC and cSCC compared with the control group. While the direction of the association is encouraging, the authors stress that the study design does not prove causation. Residual confounding factors—such as sun exposure, skin type, smoking status, and other health conditions—could still influence the results.
Key findings
– Lower observed rates of basal cell carcinoma and cutaneous squamous cell carcinoma in the supplement group compared with controls.
– No definitive conclusions about dose-response or long-term safety can be drawn from this study alone.
– The authors call for further randomized trials to confirm whether the supplement actively reduces risk and to establish optimal dosing guidance.
Implications for prevention
These findings are intriguing but should be interpreted with caution. If future research confirms a protective effect, the supplement could become part of a broader prevention strategy. However, until randomized controlled trials verify efficacy and safety, current skin cancer prevention still hinges on proven measures: daily sun protection, sun-smart behavior, and regular skin examinations.
What to consider before starting a supplement
For readers, it is important to consult a healthcare professional before starting any new supplement, especially at higher doses such as 500 mg twice daily. Supplements can interact with medications and may have side effects that vary by individual health status. Relying on a single nutrient to prevent cancer is not a substitute for established prevention practices.
Early detection matters
Alongside prevention, early detection remains a lifesaving priority. The awareness resource and checklists on skin changes can help you recognize suspicious lesions early. The PDF checklist “Hautkrebs erkennen” features a clear, illustrated ABCDE rule to help assess moles and new skin changes. This resource is available for free download.
Practical takeaways for readers
• Continue proven prevention strategies: sunscreen, protective clothing, shade, and avoidance of peak sun hours.
• If you are considering a supplement, discuss it with your clinician to weigh benefits and risks in the context of your health.
• Stay informed about new research. For the full details of the study and its context, read the complete article on 24vita.de and consult healthcare guidance before making changes to your routine.
