The prostate gland — a walnut-sized structure at the base of the bladder — affects the quality of life of millions of UK men as they age. By age 60, more than half of men have some degree of benign prostatic hyperplasia (BPH); by 85, this rises to over 90%. Understanding BPH, distinguishing it from prostate cancer, and knowing the evidence for available treatments helps men make informed choices.
What Is BPH and What Causes It?
Benign prostatic hyperplasia is a non-cancerous enlargement of the prostate gland, driven by DHT (dihydrotestosterone) stimulation of stromal and glandular cell proliferation within the prostate. It is almost universally age-related and is not the same as, or a precursor to, prostate cancer — though both can coexist. As the prostate enlarges, it compresses the urethra (which passes through its centre), producing lower urinary tract symptoms (LUTS).
Symptoms of BPH
Voiding symptoms: poor urine stream, difficulty starting urination (hesitancy), intermittent stream, straining, sensation of incomplete emptying. Storage symptoms: urgency, frequency (particularly nocturia — needing to wake to urinate at night, which disrupts sleep significantly), and urge incontinence. These symptoms significantly impair quality of life and should be assessed by a GP, who can use validated questionnaires (International Prostate Symptom Score — IPSS) to quantify severity and guide management.
Important: Always See a GP First
Before self-treating with supplements, a GP assessment is essential for several reasons. Prostate cancer can coexist with BPH and presents with similar symptoms — a PSA test and digital rectal examination provide important baseline information. Other conditions (overactive bladder, urethral stricture, urinary tract infection) also cause LUTS. A PSA test at symptom onset provides a baseline for future monitoring. This is not a condition to self-diagnose and treat without medical assessment.
Evidence-Based Supplements for BPH
Saw palmetto (320mg standardised extract daily) — inhibits 5-alpha-reductase and has anti-androgenic effects on prostate tissue. Widely used; clinical trial results are mixed — the largest trial (NEJM 2006) found no difference from placebo, but smaller studies have shown modest improvements in urinary flow and symptom scores. Well tolerated. May be more effective in specific BPH subtypes. Beta-sitosterol (60–130mg daily) — a phytosterol with the most consistent evidence among OTC prostate supplements. Multiple RCTs show improved urinary flow rate and reduced symptom scores, with a Cochrane review confirming modest but significant benefit. Pygeum africanum extract — African plum tree bark extract. A Cochrane review of 18 trials found significant improvements in urinary flow and symptom scores. Lycopene (10–15mg daily) — abundant in tomatoes, particularly cooked tomatoes and tomato paste. Epidemiological association with reduced prostate cancer risk and some evidence for reduced PSA progression.
Frequently Asked Questions About Prostate Health
What is the difference between BPH and prostate cancer?
BPH is a benign, non-cancerous enlargement. Prostate cancer is a malignant growth originating in prostate cells. Both can cause urinary symptoms; both can coexist. BPH does not cause prostate cancer. Prostate cancer may or may not cause urinary symptoms — it is often asymptomatic until advanced. PSA testing (with acknowledgment of its limitations) provides screening information but is not diagnostic on its own. Prostate cancer diagnosis requires biopsy.
Should all men over 50 have a PSA test?
PSA testing for prostate cancer in asymptomatic men is not offered by the NHS as a screening programme because the evidence for reducing mortality while avoiding harms from over-diagnosis and overtreatment is complex. Men who have concerns or risk factors (Black ethnicity, family history) can request a PSA test from their GP after a full informed discussion of its limitations. The Prostate Cancer UK “Prostate Health Check” website provides excellent decision-support resources.
Do prostate supplements prevent prostate cancer?
No supplement has been proven to prevent prostate cancer. Lycopene, selenium and Vitamin E have been investigated — the SELECT trial found Vitamin E supplementation modestly increased prostate cancer incidence. Lycopene’s association with lower prostate cancer risk in observational studies has not been confirmed in trials. A healthy diet (high vegetables, low processed meat and high-fat dairy) and healthy weight are the most evidence-based prostate cancer risk-reduction strategies.
What lifestyle changes help BPH symptoms?
Reduce evening fluid intake, limit caffeine and alcohol (bladder irritants), double voiding (urinate, wait 30 seconds, try again), avoid medications that worsen urinary symptoms where possible (decongestants, antihistamines, antidepressants). Pelvic floor exercises — yes, men have pelvic floors — can improve bladder control in BPH-associated overactive bladder.
