HelloPharmacist Scorecard of Saw Palmetto Berry Extract by Solgar

Our pharmacy team’s full take, with four database checks built into the cards below — a summary of what is known, not a grade of the product itself.

What’s inside

Full disclosure
Ingredient Transparency · database check
Full

Every active ingredient lists its own amount on the label.

Why this rating?
  • The label discloses an exact amount for 2 of its 2 active ingredients.
  • No proprietary blends here — you can verify the dose of every single component.

This product contains 2 active ingredients, both forms of saw palmetto: a powder and a standardized extract. Both deliver the same herb — the berries of the saw palmetto plant — in slightly different preparation forms to give you consistent potency.

The capsule itself is made from vegetable cellulose and includes several inactive ingredients like silica, microcrystalline cellulose, vegetable magnesium stearate, and a PhytO2X Antioxidant Blend to preserve freshness.

Does it work?

Moderate evidence
Evidence for Intended Use · database check
By FDA rules, dietary supplements can’t claim to treat, cure, or prevent disease — so labels speak in careful marketing language. We discern each product’s intended use from its name, label claims, and label statements, then grade the clinical evidence for that use. How these ratings are computed

This product doesn't appear to be marketed for a specific use, so we graded Saw Palmetto's overall clinical evidence instead.

Moderate

Some clinical evidence supports Saw Palmetto for:

Why this rating?
  • We looked at the product name, claims, and label statements and couldn't find a stated purpose to grade.
  • Since the label doesn't commit to one use, we graded the ingredient's overall clinical evidence instead.
  • On file: Transurethral resection of the prostate (TURP) — rated "Possibly Effective" (Natural Medicines).

The evidence for saw palmetto is mixed and often limited. For people recovering from transurethral resection of the prostate (TURP), a urological procedure, saw palmetto is possibly effective.

However, for benign prostatic hyperplasia (BPH) — enlarged prostate — the evidence suggests it's possibly ineffective. For other uses listed here — chronic bronchitis, male pattern baldness (androgenic alopecia), and lower urinary tract symptoms (LUTS) — we don't have enough reliable evidence to rate whether it works.

The evidence, ingredient by ingredient Saw Palmetto

How safe is it?

Well-documented data
Safety Information · database check
Well characterized

Adverse-effect, pregnancy, and general safety data are on file for most of these ingredients.

Why this rating?
  • We hold adverse-effect (side-effect) data for 1 of the 1 matched ingredient.
  • Pregnancy & breastfeeding safety ratings cover 1 of 1.
  • General safety write-ups exist for 1 of 1.
  • Remember: this measures how much safety information exists. Thin data is not the same as being safe.

Saw palmetto is generally well tolerated, and most people who take it experience only mild, infrequent, and reversible side effects. The most common ones are abdominal pain, constipation, diarrhea, dizziness, fatigue, headache, nausea, and rhinitis.

Rarely, people have reported a skin rash with blisters or changes in heart rhythm, though these are uncommon. Don't use this product during pregnancy or while breastfeeding.

The safety data advises against both because of possible effects on hormones and insufficient safety information. If you're considering saw palmetto for a prostate or urinary issue, use it only under guidance from your doctor or pharmacist.

Moderate interaction found
Known Interaction Concern · database check
Moderate identified

The most serious documented interaction for these ingredients is Moderate. Check your medications for a personalized result.

Why this rating?
  • 1 of the 1 matched ingredient can interact with medications — Saw Palmetto.
  • The most serious interaction on file is rated Moderate.
  • Some involve high-stakes drug classes: anticoagulant / antiplatelet drugs.
  • For scale: 174 individual medications appear in the full list. A big number alone doesn't make a product dangerous — what matters is whether YOUR medication is on it, so run yours through the interaction checker on this page.

Before taking this product, double-check with your doctor or pharmacist if you're on blood thinners or antiplatelet drugs (such as warfarin, dabigatran, or aspirin) — saw palmetto may increase bleeding risk. Also flag it if you take birth control pills or estrogen therapy, since saw palmetto might reduce their effectiveness.

These are the main medication types to watch.

The bottom line

Scorecard at a glanceFully disclosed formula with some supporting evidence behind its ingredients' uses. Moderate medication interactions have been identified, and safety information is well characterized.

Solgar's Saw Palmetto Berry Extract is worth a conversation with your doctor or pharmacist if you have prostate concerns — especially after certain urological procedures — but the evidence for most other uses is thin or absent. If you take blood thinners, birth control pills, or any estrogen medication, you'll need to clear this with your healthcare provider first.

Avoid it entirely if you're pregnant or nursing. Talk it over with your own doctor or pharmacist to make sure it's right for you.

Saw Palmetto Berry Extract by Solgar: Common Questions

Does Saw Palmetto Berry Extract by Solgar interact with any medications?
Yes. Based on its ingredients, Saw Palmetto Berry Extract has a known interaction with 174 medications. Use the checker to see how it interacts with a specific drug.
How can one product interact with so many drugs?
Saw Palmetto Berry Extract contains 2 active ingredients, and an interaction can come from any of them. We check every ingredient, combine the results into one list per medication, and show which ingredient and mechanism is responsible.
Where does this information come from?
The product label data comes from the NIH Dietary Supplement Label Database (DSLD); the interaction data is built on the Natural Medicines database and reviewed by HelloPharmacist pharmacists.
Can I take this if I'm on blood thinners?
No — not without checking with your doctor first. Saw palmetto is reported to prolong bleeding time, and combining it with blood thinners or antiplatelet drugs could increase your risk of bleeding. Your doctor needs to know before you start.
Will this reduce how well my birth control works?
It might. Saw palmetto appears to have antiestrogenic effects, which means it could theoretically interfere with how contraceptive drugs work. Talk with your doctor or pharmacist before adding this to your routine if you rely on birth control.
Is it safe during pregnancy or breastfeeding?
No. The safety data advises against using saw palmetto during pregnancy because of possible effects on hormones and lack of safety data. It's also not recommended while breastfeeding due to insufficient safety information. If you're pregnant or nursing and interested in this, speak with your doctor or pharmacist.
What are the most common side effects?
Most side effects are mild and infrequent. They include abdominal pain, constipation, diarrhea, dizziness, fatigue, headache, nausea, and rhinitis. These are typically reversible and go away when you stop taking it.
Does this actually work for an enlarged prostate?
The evidence is mixed. For benign prostatic hyperplasia (BPH), saw palmetto is rated possibly ineffective based on the data we hold. For recovery after prostate surgery (TURP), it's possibly effective. Talk with your doctor about whether it makes sense for your specific situation.
Can I take this for male pattern baldness?
We don't have enough reliable evidence to say whether saw palmetto works for male pattern baldness. If that's why you're interested, your doctor can discuss what the current evidence supports.
