Grape seed extract slows the progression of prostate cancer.
Grape seed extract, which is commonly used as a dietary supplement to lower cholesterol and blood pressure, may slow the progression of prostate cancer after treatment. This conclusion was reached by researchers from the University of Colorado, whose work was published in the journal Cancer Research (CR).
The study involved 41 men who had experienced a rise in prostate-specific antigen (PSA) levels after surgery or radiation therapy, indicating a possible recurrence of the disease. Patients took 150 milligrams of grape seed extract twice a day for 12 months. In 78 percent of them, the increase in PSA levels slowed, and in 37 percent, the improvement was significant: the doubling time of PSA increased by more than 30 percent.
The scientists noted that the effect was most pronounced in men with higher initial levels of testosterone and PSA. The supplement was well tolerated, causing no serious side effects. According to the lead author, Professor Paul Maroni, such supplements may help delay the need for hormone therapy, which is often accompanied by fatigue, weight gain, and decreased bone density.
The researchers emphasize that it is too early to speak of a complete therapeutic effect — larger clinical trials are needed to confirm the results.
