Saw Palmetto vs Beta-Sitosterol: Two Prostate Ingredients
Saw palmetto vs beta sitosterol is a comparison with one well-tested side and one we cannot judge here. Saw palmetto did no better than placebo for urinary symptoms in large BPH trials. Our source library holds no beta-sitosterol trial, so we make no claim about it. Prostadine names saw palmetto, not beta-sitosterol, and prints no amount.

What is the difference between saw palmetto and beta-sitosterol?
Saw palmetto is an extract of a palm berry. Beta-sitosterol is a plant sterol found in many plants, and it is sold as its own supplement.
They are different substances, so one trial result never carries over to the other. The table shows what we can and cannot document.
| Question | Saw palmetto | Beta-sitosterol |
|---|---|---|
| What it is | Palm berry extract | Plant sterol |
| Large trials in our sources | Yes, three cited below | None held |
| Named by Prostadine | Yes, no amount printed | No |
| Our verdict | No benefit over placebo in BPH trials | Cannot judge here |
What did the large saw palmetto trials find?
The large saw palmetto trials found no benefit over placebo for BPH urinary symptoms.
One year of 160 mg twice a day in 225 men did no better than placebo (Bent et al., NEJM 2006). A later trial used 320 mg up to 960 mg a day in 369 men over 72 weeks, with the same result (Barry et al. (CAMUS), JAMA 2011). A Cochrane review of 32 trials and 5,666 men agreed (Tacklind et al., Cochrane 2012). NCCIH adds that saw palmetto does not appear to change PSA (NCCIH, Saw Palmetto).
None of these tested Prostadine, and its amounts are not printed. See the saw palmetto page for the full picture.

Neither dose beat placebo for BPH symptoms.
Bars compare study doses or official limits with each other, not with Prostadine: its amounts are not printed, so its bar stays empty. No trial has tested Prostadine itself.
Is beta-sitosterol better than saw palmetto for the prostate?
We cannot say that beta-sitosterol is better. Our sources hold no trial that compares the two, and none that tests beta-sitosterol alone.
Be careful with any page that ranks them with a confident score. A ranking needs head-to-head data, and a vendor page is not that.
Ask your doctor whether any plant ingredient fits your symptoms, and what a urine flow test or PSA discussion would add. New urinary symptoms deserve an exam.
We make no claim that either ingredient helps BPH, and nothing here replaces care for it.

See packsShould you check medicines before taking either one?
Yes, check with a professional first, because herbs and sterols can interact with medicines (NCCIH, Herb-Drug Interactions). You know your medicines. We do not.
- Ask your doctor or pharmacist about tamsulosin, finasteride and dutasteride. Finasteride and dutasteride also lower PSA, which matters for screening (NCI, PSA Test).
- Ask about warfarin and other blood thinners, and before any surgery.
- Saw palmetto may be unsafe in pregnancy (NCCIH, Saw Palmetto).
Blood in urine, fever with painful urination, severe belly, back or side pain, or no urine at all needs same-day care. If you cannot urinate, go to the emergency room.
Prostadine is one example of a product that names saw palmetto among nine ingredients with no amounts; read the medicines guide before using it.

FAQ01
Quick answers on these two ingredients
Does beta-sitosterol appear in Prostadine?
No. The sales page names nine ingredients: nori, wakame, kelp, bladderwrack, saw palmetto, pomegranate, iodine, shilajit and neem. Beta-sitosterol is not among them. No amounts are printed for any of the nine.
Can I take saw palmetto and beta-sitosterol together?
We cannot say it is safe. We hold no source on combining them, and you may take medicines we do not know about. Ask your doctor or pharmacist before combining two supplements, especially with a blood thinner or prostate medicine.
Why do the saw palmetto trials still get mentioned if they failed?
They are the largest controlled tests, so they set the bar. They found no benefit over placebo for BPH urinary symptoms, but they tested specific extracts and doses. They do not prove harm and they do not test other products.
