Cranberry fruit powder more effective than placebo at reducing urinary symptoms

This study evaluated the effectiveness of Flowens (a cranberry fruit powder) as an alternative treatment for benign prostatic hyperplasia (BPH). Researchers report preliminary evidence that Flowens can reduce BPH-related urinary symptoms.

BPH can lead to bothersome urinary symptoms that can impact quality of life. The occurrence of BPH-related urinary symptoms typically increases with age. Symptoms can include overactive and underactive bladders. Surgery or drug therapy is often required to help manage symptoms. However, not all men respond to, or tolerate, these treatments. Herbal therapies have been under investigation as a possible alternative. Early studies are suggesting that cranberry fruit powder, such as Flowens, can reduce urinary symptoms in men with BPH.

The aim of this study was to evaluate the effects of Flowens on BPH-related urinary symptoms.

A total of 124 men were included in this study. All men were aged 45 or older and had moderate to severe urinary symptoms due to BPH. Men were randomly allocated to receive treatment with either Flowens or placebo (control substance with no active effect on the body). Men receiving Flowens were further allocated to different dosages (250 or 500 mg). Treatment outcomes were followed for 6 months.

6-month daily intake of Flowens was effective at reducing urinary symptoms. Both dosages significantly improved urinary symptoms compared to placebo. However, the higher dosage was found to be even more effective. Urinary flow rate, complete bladder emptying, and bladder volume were all significantly improved with 500 mg of Flowens compared to placebo. No side effects were observed.

Researchers concluded that Flowens significantly reduced BPH-related urinary symptoms. 

This was a relatively small study. The researchers advised that larger clinical trials are needed before Flowens can be recommended as an alternative treatment for BPH.
