A 68-year-old man, who recently had his prostate removed and completed radiation therapy, is facing a critical health decision. After years of taking a daily multivitamin, he learned that some ingredients might actually heighten his risk of prostate cancer.

This health-conscious individual takes Centrum Silver, fish oil, calcium, and vitamin D, but recent research has raised alarms about the safety of certain vitamins like selenium and vitamin E in patients with a history of prostate cancer. With conflicting information swirling around the benefits and risks associated with fish oil, he’s left wondering if his long-time vitamin regimen might have worsened his condition.

In a response filled with important insights, Dr. Roach highlighted the growing evidence linking vitamin E to an increased risk of prostate cancer, citing a major study that had to be halted due to safety concerns. The findings suggested a significant 17% rise in cancer risk among those taking vitamin E.

While fish oil's effects remain controversial, Dr. Roach advised that men at risk of prostate cancer should steer clear of vitamin E, and unless there is a clinical reason for taking fish oil, it may be best to avoid it as well.

The multivitamin in question contains both vitamin E and selenium—two components potentially dangerous for prostate cancer survivors. Dr. Roach recommended a straightforward stop rather than a gradual tapering process.

When it comes to diet, he emphasized the benefits of a plant-based approach, rich in fruits, vegetables, and whole grains, while limiting red meat and refined carbs. Incorporating healthy fats is also beneficial, and while green tea may offer unproven advantages, it has not been ruled out for its potential benefits.

In a related letter, an older gentleman sought clarification on whether to fast before a metabolic blood test, as instructed by his nephrologist. Despite his instinct to follow traditional guidelines of fasting for accurate results, Dr. Roach reassured him that adhering to the doctor’s non-fasting direction would provide a valid snapshot of his body’s chemistry.

Overall, if you’re taking supplements while dealing with health concerns, consulting a healthcare professional is essential. It might be time to reevaluate the vitamins you’re depending on—your health could be at stake!
