The prostate is an important male gland that secretes a fluid found in semen.1 In addition, the urethra (the tube through which urine flows) runs through the prostate, so changes in prostate structure, such as prostate enlargement, can profoundly and negatively affect urinary function. The most common issue that impacts prostate health for most men is benign prostatic hyperplasia. A more serious, common issue is prostate cancer. This article will review these problems, and consider some key nutraceuticals that may help.

Benign prostatic hyperplasia (BPH)

Benign prostatic hyperplasia (BPH) is a common enlargement of the prostate gland as a man ages. Though the prostate continues to grow during most of a man’s life, the enlargement doesn’t usually cause symptoms before age 40, but more than half of men in their sixties, and as many as 90 percent in their seventies and eighties have some symptoms of BPH. These symptoms stem from obstruction of the urethra and gradual loss of bladder function, which results in incomplete emptying of the bladder. Imagine the prostate as a donut shaped gland, and as the prostate swells up and enlarges, the internal diameter of the donut hole gets smaller, squeezing the urethra. The symptoms of BPH vary, but the most common ones involve changes or problems with urination, such as:

a hesitant, interrupted or weak stream

urgency and leaking or dribbling

more frequent urination, especially at night

The size of the prostate does not always determine how severe the obstruction or the symptoms will be. Some men with greatly enlarged glands have little obstruction and few symptoms while others, whose glands are less enlarged, have more blockage and greater problems.

Prostate cancer

Prostate cancer is the third most common cause of death from cancer in men of all ages and is the most common cause of death from cancer in men over age 75. Prostate cancer is rarely found in men younger than 40. Men who are at higher risk include those who are older than 60, have a family history of prostate cancer, abuse alcohol, eat a diet high in fat (especially animal fat), have been exposed to cadmium, and are African- American. The symptoms listed below can occur with prostate cancer, usually at a late stage (although they may also be caused by BPH):

Delayed or slowed start of urinary stream

Dribbling or leakage of urine, most often after urinating

Slow urinary stream

Straining when urinating, or not being able to empty out the bladder

Blood in urine or semen

Nutraceuticals for prostate health

There are a several nutraceuticals with research that support their use in promoting healthy prostate function. Five of these include beta-sitosterol, zinc, selenium, vitamin D and boron.


Beta-sitosterol, a natural plant sterol commonly found in some foods, has shown in research to effectively treat symptoms of BPH. For example, in a 6-month, multi-center, doubleblind, placebo-controlled trial published in the British Journal of Urology2 177 patients with BPH were treated using 130 mg beta-sitosterol daily, or placebo. Results showed significant (P < 0.01)a improvements over placebo in those treated with beta-sitosterol, as measured by the International Prostate Symptom Scoreb (IPSS) and the quality-of-life index. There were also significant improvements in peak urinary flow rate and bladder emptying. A similar 3-month study3 in a Japan using 180 mg of beta-sitosterol daily also found significant (p < 0.05) improvements in BPH symptoms.

In a 6-month, randomized, double-blind, placebo-controlled multi-center study in the Lancet,4 200 patients with BPH were treated with 60 mg beta-sitosterol daily or placebo. Results showed significant improvements in the modified Boyarsky score (a measurement of BPH symptoms) as well as a significant decrease in IPSS. Furthermore, there were improvements in peak urine flow bladder emptying, which remained unchanged in the placebo group (p < 0.01). In an 18-month follow-up study,5 38 patients of the patients who continued beta-sitosterol treatment had stable values for all outcome variables. Of the former placebo group, 27 patients who started beta-sitosterol after the double-blind trial improved to the same extent as the treated group for all outcome variables.

Perhaps most significantly, a review6 and a meta-analysis7 examined the results of several randomized, placebo-controlled, double-blind trials in which beta-sitosterol was used in treating BPH in 519 men. As with the aforementioned studies, these also demonstrated significant improvements in BPH symptoms. It should be noted that one of the studies8 reviewed in the metaanalysis found that beta-sitosterol decreased the number of times each night that men with BPH had to get up to urinate.


Zinc plays important roles in the immune response, neurological function, and reproduction.9 This mineral’s importance to prostate health is easily demonstrated by the fact that the prostate has a higher concentration of zinc than any other organ of the body.10 Furthermore, there are higher concentrations of zinc in seminal fluid (much of which is secreted by the prostate) than in other body fluids.11 This means that each time a man ejaculates he loses some zinc?which needs to be replaced. In addition, zinc levels have been found to decrease in the prostate tissue and prostatic fluid in men with prostatic carcinoma.12,13


Epidemiologic studies14 have shown that: 1) higher levels of the mineral selenium may slow prostate cancer tumor progression, 2) selenium seems to accumulate in the prostate, and 3) selenium protects against DNA damage and increases apoptosis (programmed cell death) in cancer cells.

Other research15 reported that selenium levels were significantly lower in those with prostate cancer. Furthermore, in a case-control study,16 181 men with advanced prostate cancer and 181 matched controls were examined. The results were that individuals whose average dietary intake of selenium was 159 mcg/day had a 65 percent lower risk of advanced prostate cancer compared to those with an average intake of 86 mcg/day. Other research17 has found that the risk of developing prostate cancer was 50 percent less in men with higher serum selenium levels compared to those with the lowest intake. Similarly, a case-control study18 found that men with the lowest selenium intake were four to five times more likely to develop prostate cancer than those with the highest selenium intake.

Vitamin D

Epidemiological studies19 show correlations between the risk factors for prostate cancer and conditions that can result in decreased vitamin D levels. Furthermore, the active metabolite of vitamin D inhibits the growth of human prostate cancer cells. Other research20 with prostate cells further support the idea that increasing vitamin D levels may be useful in preventing prostate cancer. In addition, a study21 of Finnish men found that low serum vitamin D levels were associated with earlier and more aggressive prostate cancer development.


Research22 has found that groundwater boron levels correlated with a decrease in prostate cancer incidence and mortality, and that a common form of boron in-vitro improves the antiproliferative effectiveness of chemo-preventative agents. Furthermore, analyzed data23 from the third National Health and Nutrition Examination Survey (NHANES III) compared boron intake of 95 prostate cancer cases with that of 8,720 male controls. After controlling for age, race, education, smoking, body mass index, dietary caloric intake, and alcohol consumption, increased dietary boron intake was associated with a decreased risk of prostate cancer with a dose-response pattern.


There is no single magic bullet for guaranteeing a healthy prostate. However, the use of one or more of the nutraceuticals discussed in this article may help support healthy prostate function.
