HelloPharmacist Scorecard of Saw Palmetto Extract 320 mg by NOW
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
This softgel contains two active ingredients: pumpkin seed oil and saw palmetto berry extract at 320 mg total. The pumpkin seed oil is included for its potential benefit to urinary and prostate health, while saw palmetto is the primary active traditionally used for prostate and urinary tract concerns.
The capsule itself is a vegetarian softgel (an inactive ingredient that holds the oils).
Does it work?
Moderate evidence
The evidence for this product is mixed. Saw palmetto shows possibly ineffective evidence specifically for benign prostatic hyperplasia (BPH) — the most common reason people use it — though it shows possibly effective results for one related condition (TURP).
Pumpkin seed oil rates as possibly effective for BPH, so there's some support for that ingredient. For other uses like hair loss, UTIs, and cystitis, the evidence we hold is insufficient to rate either ingredient.
Talk with your doctor about what the research actually supports for your particular concern.
How safe is it?
Well-documented data
Pumpkin seed oil is generally well tolerated in adults, though the most common side effects in trials are mild abdominal discomfort, diarrhea, nausea, and vomiting. Saw palmetto is also well tolerated with mild, reversible side effects — most commonly abdominal pain, constipation, diarrhea, dizziness, fatigue, headache, nausea, and vomiting.
A rare case of anaphylaxis with pumpkin and occasional heart rhythm issues with saw palmetto have been reported. Pregnancy and breastfeeding: saw palmetto is rated Likely Unsafe in pregnancy because of possible hormone effects and lack of safety data — the safety data advises against use.
Saw palmetto is also unsafe while breastfeeding. For pumpkin seed oil, there isn't enough data on concentrated supplements during pregnancy or breastfeeding to know either way.
Talk with your doctor or pharmacist about whether this product is right for you if you're pregnant, trying to conceive, or breastfeeding.
Meds to double-check
Moderate interaction found
Before taking this product, double-check with your doctor or pharmacist if you take birth control pills or estrogen therapy (saw palmetto may reduce their effectiveness), blood thinners or antiplatelet drugs like warfarin or aspirin (Moderate risk of increased bleeding from saw palmetto), or lithium for a mood disorder (pumpkin seed oil may raise its levels). No interactions are documented for the inactive ingredients we could check.
The bottom line
Scorecard at a glanceFully disclosed formula with some supporting evidence for its stated purpose. Moderate medication interactions have been identified, and safety information is well characterized.
This product may help with certain urinary or prostate concerns, though the evidence for its most common use (BPH) is limited. The biggest caution is if you take birth control pills, hormone therapy, blood thinners, or lithium — those warrant a conversation with your doctor or pharmacist first.
If you're pregnant or breastfeeding, check with them before starting.
