Quick answer: the best saw palmetto supplement for most men is a softgel with 320 mg of standardized saw palmetto extract per day, such as NOW Saw Palmetto Extract 320 mg, because that is the form and dose used in clinical trials. Berry powder capsules are cheaper but are not the same thing as an extract. Be realistic, though: the largest reviews found saw palmetto works about as well as placebo for urinary symptoms.
Looking for the best saw palmetto supplement for prostate health? Saw palmetto (Serenoa repens) is the most popular herbal supplement for an enlarged prostate, and store shelves are full of bottles that look alike but contain very different things. Some hold a concentrated oil extract. Others hold ground berries.
This guide ranks five options, explains which form to buy and tells you plainly what the research says. Urinary symptoms can have serious causes, so see a doctor before you self-treat. Start with what causes enlarged prostate symptoms and BPH treatment options compared.

The 5 best saw palmetto supplements reviewed
1. NOW Saw Palmetto Extract 320 mg: best overall
NOW uses a concentrated saw palmetto oil extract in a softgel, the same form tested in most clinical trials. Each softgel supplies 320 mg, so one a day reaches the standard research dose. It also includes pumpkin seed oil.
The Amazon listing below is a multi-pack of three 90-softgel bottles, which is roughly a nine-month supply at one softgel a day.
Best for: men who want the form and dose used in studies. Skip if: you avoid gelatin softgels.
- 3 pack
- Supports Healthy Prostate Function*
- With Pumpkin Seed Oil
2. Life Extension Ultra Prostate Formula: best multi-ingredient formula
This formula pairs 320 mg of saw palmetto extract with other common prostate ingredients, including beta-sitosterol, pygeum, stinging nettle root, pumpkin seed and lycopene. The serving is two softgels a day.
The bottle holds 60 softgels, a one-month supply. The formula also includes Boswellia and a pollen extract.
Best for: men who want several prostate ingredients in one product. Skip if: you want to test saw palmetto on its own.

3. Nature’s Way Saw Palmetto Berries: best whole-berry option
This is ground saw palmetto berry, not an extract. Each vegan capsule holds 585 mg of berry powder, and the label suggests one capsule three times a day with food.
Berry powder contains far less of the fatty acids found in an oil extract, so 585 mg of powder is not equal to 320 mg of extract. Choose it if you prefer a traditional whole herb.
Best for: vegans and men who want the whole berry. Skip if: you want a standardized extract.

4. Nutricost Saw Palmetto: best budget organic pick
Nutricost supplies 1,000 mg of organic saw palmetto per two-capsule serving (500 mg per capsule), with 60 servings in a bottle. The capsules are vegetarian and the product is certified organic by CCOF.
The label does not state a fatty-acid percentage, so you cannot compare it directly with a standardized softgel.
Best for: low cost per serving and an organic label. Skip if: a stated standardization matters to you.
- 120 Capsules, 60 Servings of Organic Saw Palmetto Per Bottle
- Serving Size of 2 Easy-to-swallow Vegetarian Capsules
- 1,000mg of Organic Saw Palmetto Extract Per Serving (500mg Per Capsule)
5. Nature’s Bounty Saw Palmetto 450 mg: best value big bottle
Nature’s Bounty sells 250 capsules of 450 mg saw palmetto derived from the berry. The label suggests one capsule three to five times a day, so the bottle lasts about two to three months.
Like the Nature’s Way pick, this is not a concentrated oil extract.
Best for: the lowest price per capsule from a mainstream brand. Skip if: you dislike taking several capsules a day.
- Has been traditionally used to support urinary flow (1)
- Derived from the berry of the Saw Palmetto tree
- Adult men can take one capsule three to five times daily, preferably with meals, to help support prostate and urinary he…
NOW Foods vs Life Extension saw palmetto: which is better?
NOW Foods is the better choice if you want saw palmetto on its own, and Life Extension is better if you want a full prostate formula. Both supply 320 mg of saw palmetto extract a day, the dose used in most trials.
| NOW Saw Palmetto Extract | Life Extension Ultra Prostate Formula | |
|---|---|---|
| Saw palmetto per day | 320 mg extract (1 softgel) | 320 mg extract (2 softgels) |
| Other ingredients | Pumpkin seed oil | Beta-sitosterol, pygeum, stinging nettle root, pumpkin seed, lycopene |
| Softgels a day | 1 | 2 |
| Cost per day | Lower | Higher |
| Best for | Testing saw palmetto alone | One product with several prostate ingredients |
Choose NOW Foods if you want to find out whether saw palmetto helps you, at the lowest daily cost. Choose Life Extension if you prefer one product that also contains beta-sitosterol and pygeum, which have somewhat better trial results than saw palmetto alone. We compare those two ingredients in beta-sitosterol vs saw palmetto and pygeum vs saw palmetto.
Saw palmetto extract vs berry powder: which is better?
Extract is the better-studied form. A saw palmetto extract is an oil pulled from the berries and usually standardized to 85–95% fatty acids and sterols. Berry powder is just dried, ground fruit, with a much lower fatty-acid content.
Almost every clinical trial used an extract at 320 mg a day. No good trial shows that berry powder does the same job, so the best saw palmetto supplement for anyone following the research is an extract softgel.
Does saw palmetto actually work for an enlarged prostate?
Probably not much. A 2023 Cochrane review pooled 27 trials with 4,656 men and found that saw palmetto alone gave little to no improvement in urinary symptoms or quality of life compared with placebo.
Two large U.S. trials agree. The STEP trial tested 160 mg twice a day for a year. The CAMUS trial raised the dose to three times the standard amount. Neither beat placebo.
The good news is safety. Side effects in these trials were mild and about as common as with placebo. For options with stronger evidence, see BPH treatment options.
How much saw palmetto should you take per day?
The standard dose is 320 mg of extract a day, taken as one 320 mg softgel or 160 mg twice a day. Take it with food to limit stomach upset. For berry powder there is no research-backed dose, so follow the label.
Saw palmetto vs beta-sitosterol and pygeum
Beta-sitosterol and pygeum are the other common prostate ingredients. Small, older trials suggest both may modestly improve urinary flow, but the studies were short. Formulas such as Life Extension combine all three. Our guide to the best prostate supplements compares them.
How we chose the best saw palmetto supplement
We compared each product on four points:
- Form: oil extract or berry powder, stated clearly on the label.
- Dose: how easily it reaches 320 mg of extract a day.
- Quality: an established brand with GMP manufacturing.
- Value: cost per day, not per bottle.
We read the labels and Amazon listings for every pick. We did not run our own lab tests.
When should you see a doctor instead?
See a doctor before starting if you have urinary symptoms that are new or getting worse. Seek care quickly for blood in the urine, pain, fever or being unable to urinate. A supplement should never delay a check-up, because prostate cancer and BPH can cause similar symptoms. Read prostate cancer vs BPH and our PSA test guide.

Saw palmetto FAQ
What is the best saw palmetto supplement?
For most men it is a softgel with 320 mg of standardized saw palmetto extract, such as NOW Saw Palmetto Extract 320 mg. That is the form and dose used in clinical trials.
Which brand of saw palmetto is best?
NOW is our top pick for a plain standardized extract. Life Extension is best for a multi-ingredient formula, Nature’s Way for whole berry powder, and Nutricost or Nature’s Bounty for a low price.
Is saw palmetto extract better than berry powder?
Extract is better studied. It concentrates the fatty acids from the berry, and nearly all trials used 320 mg of extract a day. Berry powder has much less of these compounds and no research-backed dose.
Does saw palmetto actually work for BPH?
The evidence is weak. A 2023 Cochrane review of 27 trials with 4,656 men found little to no improvement in urinary symptoms compared with placebo. It is, however, well tolerated.
How much saw palmetto should I take?
The standard dose is 320 mg of extract a day, as one softgel or 160 mg twice a day, taken with food.
How long does saw palmetto take to work?
Trials usually ran for months. Give it two to three months before judging it, and see a doctor if symptoms do not improve.
Does saw palmetto lower testosterone or cause ED?
Trials have not shown that it lowers testosterone. Sexual side effects were rare and about as common as with placebo.
Is saw palmetto safe with prostate medications?
Ask your doctor first, especially if you take finasteride, dutasteride, tamsulosin or a blood thinner, or if you have surgery planned.
Does saw palmetto affect PSA results?
The large CAMUS trial found no meaningful change in PSA. Still, tell your doctor about any supplement you take before a PSA test. Read more in does saw palmetto lower PSA?
Softgels or capsules: which is better?
Softgels usually hold the oil extract and capsules usually hold berry powder. If you want the researched form, choose a softgel that lists 320 mg of extract.
Bottom line
The best saw palmetto supplement for most men is a 320 mg standardized extract softgel such as NOW, because it matches the research. Pick Life Extension for an all-in-one formula, or Nature’s Way if you want the whole berry. Keep expectations modest, give it two to three months and talk to your doctor about symptoms that persist.
