In the pygeum vs saw palmetto debate, pygeum has the slightly better evidence for easing urinary symptoms from an enlarged prostate, but that evidence is old, small and short-term. Saw palmetto has been studied far more rigorously, and the large, high-quality trials found it works no better than placebo on its own. That includes saw palmetto for frequent urination: the best trials found it does little or nothing to cut nighttime bathroom trips.
Neither is a substitute for a medical check-up. Urinary symptoms such as weak flow, urgency or waking at night to pee can come from benign prostatic hyperplasia (BPH), infection, bladder problems or, less often, prostate cancer, so get them looked at before you self-treat.
Key takeaways
- Saw palmetto alone: high-quality trials show little or no benefit
- Pygeum: small, short, older trials suggest modest relief
- Neither shrinks the prostate like prescription drugs
- Get urinary symptoms checked by a doctor first

What the research says about saw palmetto
Saw palmetto was once the go-to prostate supplement, and it is still the most common one on store shelves. The research has not been kind to it. We cover it in more depth in our saw palmetto for prostate symptoms article, but the key studies are:
- The STEP trial (2006). 225 men with moderate to severe BPH symptoms took 160 mg of saw palmetto twice daily or placebo for a year. Saw palmetto did not improve symptom scores or any secondary measure.
- The CAMUS trial (2011). 369 older men took escalating doses up to three times the standard 320 mg daily dose. Even at high doses, saw palmetto did not reduce urinary symptoms more than placebo.
- Cochrane review (2023). Pooling 27 randomized trials and 4,656 men, the reviewers concluded with high certainty that saw palmetto alone makes little or no difference to urinary symptoms or quality of life, in the short or long term. Combinations with other herbs may also make little or no difference, but that evidence is weaker.
There is one nuance. A 2020 meta-analysis of about 1,080 men found that 320 mg of saw palmetto daily produced similar symptom scores to the prescription drug tamsulosin over six months or more, while tamsulosin did better at reducing prostate volume. Head-to-head trials without a placebo arm are harder to interpret, though, so the placebo-controlled data carry more weight.
Saw palmetto and frequent urination: does it help?
Frequent urination, especially getting up at night to pee (nocturia), is the symptom most men hope saw palmetto will fix. The best evidence says it probably won’t. In the 2023 Cochrane review, saw palmetto made little or no difference to nighttime urination compared with placebo. The STEP and CAMUS trials also found no meaningful improvement in urinary symptom scores, which include how often men need to go during the day and night.
Pygeum looks somewhat better on this specific symptom. In its older trials, nighttime urination fell by about 19% compared with placebo, though those studies were small and short (see below).
It’s also worth knowing that frequent urination has many causes besides an enlarged prostate, including overactive bladder, type 2 diabetes, urinary or prostate infections, diuretic (“water pill”) medications, and evening caffeine or alcohol. Simple habits often help more than any herb:
- Stop drinking 2–3 hours before bed, but keep your total daily fluids up.
- Cut back on caffeine and alcohol, especially later in the day.
- Double void: after urinating, wait a few seconds and try again to empty your bladder more fully.
- Train your bladder and pelvic floor. Gradually stretch the time between bathroom trips, and try Kegel exercises for men.
See a doctor if you regularly get up more than twice a night, or if frequent urination comes with burning, blood in the urine, fever, a weak stream, or increased thirst and fatigue, which can be a sign of diabetes.
What the research says about pygeum
Pygeum comes from the bark of Prunus africana, a tree found in the mountain forests of Africa. Its extracts contain plant sterols and other compounds thought to reduce inflammation in prostate tissue, though the exact mechanism is not proven.
The main evidence is a 2002 Cochrane review of 18 randomized trials with 1,562 men. Most trials lasted about two months (range: one to four months). Compared with placebo:
- Men on pygeum were about twice as likely to report overall symptom improvement
- Nighttime urination fell by about 19%
- Leftover urine in the bladder after peeing dropped by about 24%
- Peak urine flow rose by about 23%
These are encouraging numbers, but the limitations are significant. The trials were small and short, used different doses and preparations, rarely used standard validated symptom scores, and only one clearly reported how participants were assigned to groups. No trial compared pygeum with standard BPH drugs. Later reviews have added little, and no large modern trial exists. The US National Center for Complementary and Integrative Health describes pygeum’s evidence as limited and of low quality.
So which is better?
On current evidence, pygeum has a modest edge, mainly because saw palmetto has been tested thoroughly and come up short, while pygeum has never been put through a large, long, modern trial. It is possible pygeum would also disappoint in that kind of study. Saw palmetto’s failure in well-run trials is the reason many urologists no longer recommend it.
A practical way to think about it:
- If your symptoms are mild and your doctor has ruled out other causes, a 2–3 month trial of a standardized pygeum extract (around 100 mg daily) is a low-risk experiment. Stop if you notice no change.
- If you already take saw palmetto and feel it helps, there is no urgent safety reason to stop, but be aware that the strongest trials found no benefit beyond placebo.
- If symptoms are moderate or worsening, prescription treatments such as alpha-blockers and 5-alpha reductase inhibitors have much stronger evidence.

Can you take pygeum and saw palmetto together?
Many prostate formulas combine the two, often with beta-sitosterol, zinc or nettle root. There is no strong evidence that combining them works better than either alone; the 2023 Cochrane review found combinations of saw palmetto with other herbs may make little or no difference, with low-certainty evidence. Combination products also make it harder to know which ingredient, if any, is helping you. If you try a combination, choose one that lists each ingredient’s dose rather than a proprietary blend; our guide to reading a supplement label shows what to look for.
Safety and interactions
Safety notes. Both herbs are generally well tolerated in studies. Pygeum can cause mild stomach upset, nausea, diarrhea, constipation or headache. Saw palmetto can cause mild stomach discomfort. Tell your doctor before starting either if you take blood thinners, hormone therapy or prescription BPH medication, or if you are due for a PSA test, so results can be interpreted correctly. See a doctor promptly for blood in the urine, painful urination, fever, or inability to pass urine.
There is also an environmental angle. Wild pygeum trees have been heavily overharvested for their bark, and the species is protected under international trade rules. If you buy pygeum, look for brands that state sustainable or certified sourcing.
The bottom line
Pygeum vs saw palmetto comes down to weak-but-positive evidence versus strong-but-negative evidence. Pygeum is the more reasonable herbal option to try for mild symptoms, with modest expectations and a doctor’s check-up first. For more on supporting health as you age, visit our healthy aging hub.

FAQ
Does saw palmetto help with frequent urination?
Probably not much. A 2023 Cochrane review of 27 trials found saw palmetto makes little or no difference to urinary symptoms, including how often men get up at night. Pygeum’s smaller, older trials showed about 19% fewer nighttime trips than placebo.
Is pygeum better than saw palmetto?
Pygeum has modestly positive results from small, short trials, while saw palmetto failed to beat placebo in large, high-quality trials. That gives pygeum a slight edge, but its evidence is low quality.
Can you take saw palmetto and pygeum together?
Many men do, and both are generally well tolerated, but there is no good evidence that the combination works better than either alone. Check with your doctor, especially if you take other medicines.
How long does it take for pygeum to work?
In the trials, effects were measured after about one to four months. If you notice no change after two to three months, it is unlikely to help.
What are the side effects of pygeum?
Side effects in studies were mild and similar to placebo, mainly stomach upset, nausea, diarrhea, constipation or headache.
