Summary This placebo-controlled double-blind study carried out by the Harvard Medical School investigated whether long-term multivitamin supplementation decreases the risk of cancer among men. 14,641 men aged 50 years or older, including 1312 men with a history of cancer, were included. In the study of 14 years, participants were given daily doses of a multivitamin…
Summary This randomized controlled double-blind study examined the effects of a polyphenol-rich nutritional supplement on prostate-specific antigen (PSA), an important tumor marker for prostate cancer. Towards this goal, over a period of 6 months, 199 prostate cancer patients with an average age of 74 years received either a capsule containing various micronutrients – pomegranate, green…
Summary In this research article the benefit of dietary supplementation with vitamin D3 in patients with prostate cancer was demonstrated. The researchers reported that daily supplementation with 4000 international units (IU) of vitamin D3 was effective in improving outcome patients with early prostate cancer. Furthermore, it was found that African-American men had lower overall vitamin…
Summary This US study examined the influence of the plant ingredient sulforaphane on prostate cancer. The investigation was carried out with various prostate cancer cell types and included an accurate analysis of gene expression, i.e. the process through which the genetic information was implemented and made available for cells. This kind of study enables, for…
Summary In this study the effectiveness of the carotenoid lutein against prostate cancer cells was examined. The study was conducted at the University of New Jersey (USA) and showed that lutein inhibits the growth of prostate cancer cells and promotes their death. Further details can be found in the study.

Summary The aim of this study was to determine vitamin D levels in prostate cancer patients and the influence of these on the severity and progression of the disease. 53 male patients with prostate cancer participated in the study. Various diagnostic tests, such as biopsy or immunochemical methods, provided evidence that lower vitamin D levels…
Summary In this study, the effect of a micronutrient combination containing lysine, proline, arginine, ascorbic acid and epigallocatechin gallate was tested on human prostate cancer cells. The study results show that the micronutrients effectively inhibited the growth and proliferation of cancer cells. Furthermore, the production of collagen-digesting enzymes – via which the cancer cells move…
Summary At the Dr. Rath Research Institute for Cellular Medicine, a specific combination of micronutrients – including vitamin C, lysine, proline and green tea extract – was examined for its ability to inhibit specific enzymes that help cancer cells spread through the body (metastasis). The analysis of prostate cancer cells proved that the micronutrient combination…
Summary This study was concerned with the effect of vitamin D (1,25 Dehydroxyvitamin D – the active form of the vitamin) on testicular cancer cells. For this purpose cells and tissue of testicular tumors were examined. It turned out that vitamin D has an inhibitory effect on the growth of testicular tumor cells. The authors…
