Men improve flow with cranberries

Cranberry juice isn’t just for women anymore. A new study finds that cranberries also help men improve their prostate and urinary function.

For the study, Czech researchers recruited 42 men with lower urinary tract symptoms (LUTS). LUTS is a common problem that affects about 40 percent of older men. Symptoms include slow flow, dribbling, hesitancy, and incomplete voiding.

The men in the study also had benign prostatic hyperplasia (or BPH), elevated PSA levels, and non-bacterial prostatitis. The researchers wanted to see if taking a cranberry extract would improve urinary function in men with these pre-existing conditions. So they gave half of the men 1,500 mg per day of dried cranberry extract for six months. The other men received a placebo during the same timeframe.

According to published research, the men taking the cranberry supplement showed significant improvements in six different areas:

  • Healthier scores on the International Prostate Symptom test
  • Increased urinary flow
  • Decrease in the amount of urine left in bladder after voiding
  • Increase in total volume of urine
  • Reduced PSA levels
  • Overall improvement in quality of life

In addition, the men taking the cranberry extract reported zero side effects. (That’s an important factor, when you consider the serious side effects associated with most prescription drugs used to treat BPH.) On the other hand, the men taking the placebo experienced no improvements in urinary or prostate function.

Seven steps to a healthier prostate

Last May, I talked about six steps to follow for a healthier prostate. And based on the results of the Czech research, you may want to consider adding a seventh step and take some cranberry extract every day…especially if you’re over 50 and suffer from BPH or urinary problems.

Dried cranberry extract is pretty easy to find. It comes in capsule form. Just make sure to give it some time before you expect to see any results. It may even take six months of steady supplementation before you experience any improvements in urinary flow.

    This is a very good article. I wonder if men would get the same benefit from eating cranberries as opposed to a supplement.

  2. says

    I believe because of it’s anti-adhesive properties, cranberry is also beneficial for men as it washes away bacteria and other harmful objects from the urinary tract.

    reducing PSA number is only masking possible PCA
    this is no big benefit to men
    Saw P does the same
    We want pomegranite lycopene etc to stop/apoptosis the PCA
