When you want to avoid prostate cancer, you need to take vitaminD. A study published May 2014 in Clinical Cancer Research found that low vitamin D blood levels were associated with a high risk of developing prostate cancer. Researchers under Rick Kittles from the Department of Medicine, University of Illinois at Chicago examined data from 667 men with elevated PSA levels. They were aged 40 to 79. While normal vitamin D levels are usually between 30 and 80 ng/ml, these patients’ levels were typically under 20 ng/ml.
Patients with prostate biopsies that were positive for cancer (44% of the men in this study) were found to have low vitamin D levels in their blood. Among this group of prostate cancer patients some had vitamin D levels less than 12 ng/ml; their prostate cancers were more aggressive and advanced than in men with normal vitamin D levels. The study suggests that vitamin D levels (which is determined as 25-hydroxyvitamin D) can be a marker for advanced prostate tumor progression. Men should be screened for vitamin D levels and if levels are found to be low, higher vitamin D3 supplements should be given until they reach normal levels.
