Short-term effects of a dietary supplement on lower urinary tract symptoms.

ABSTRACT

Benign prostatic hyperplasia (BPH) is one of the most common conditions affecting men over 40 years of age, typically manifesting itself with lower urinary tract symptoms (LUTS). Recently, research interest has focused in discovering a viable nutraceutical alternative to the drugs that are currently the first line of treatment for BPH. The aim of this study was to investigate the efficacy and safety of a dietary supplement containing curcumin, beta-sitosterol and oligomeric proanthocyanidins in a group of BPH/LUTS patients. One-hundred men with LUTS caused by BPH were enrolled in this study and agreed to take one tablet a day of the test dietary supplement for three months. Several parameters, such as International Prostate Symptom Score (IPSS), degree of urinary obstruction and average urinary flow were evaluated at different time points. Significant improvement in LUTS was seen after one month of treatment and a significant decrease in mean IPSS index was evident after three months of treatment. Moreover, a comparison of the mean urinary flow and of the number of subjects with bladder obstruction at three months versus one month of treatment shows a significant improvement. The study results suggest that the dietary supplement is effective for almost all the symptoms investigated, including the reduction of IPSS score and the increase of urinary flow. Moreover, the dietary supplement proved to be safe and well tolerated by the great majority of the enrolled subjects. .
