HelloPharmacist Scorecard of PalmettoGuard by Life Extension
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
PalmettoGuard has 4 active ingredients. Rosemary leaf extract, traditionally used for memory support, provides antioxidants and plant compounds.
Saw palmetto fruit extract is included for prostate health. Boron is a trace mineral, and beta-sitosterol is a plant sterol that may help with cholesterol and prostate function.
The softgel also contains several inactive ingredients — pumpkin seed oil, gelatin, glycerin, sunflower lecithin, purified water, and caramel color — that serve as the capsule and carrier.
Does it work?
Strong evidence
Rosemary extract is possibly effective for memory support. The evidence for its use in age-related cognitive decline, hair loss, or fatty liver disease is insufficient to rate.
Boron is likely effective for boron deficiency and possibly effective for yeast infections and skin damage from radiation. Beta-sitosterol is likely effective for benign prostate enlargement and possibly effective for high cholesterol and heart disease.
We don't have effectiveness data on file for Total Fatty Acids or Saw Palmetto fruit extract in this context.
How safe is it?
Well-documented data
Rosemary is safe in normal food amounts, but concentrated extracts require caution. Medicinal doses should be avoided in pregnancy and breastfeeding due to limited data.
Topical use can cause allergic reactions, lip or gum swelling, or — rarely — occupational asthma. It may also cause photosensitivity in sensitive people, and the undiluted oil could theoretically trigger seizures.
Boron is generally well tolerated at low doses below 20 mg daily, but high doses can be toxic and are unsafe in pregnancy and breastfeeding. Common side effects at normal doses are minimal, but chronic high doses can cause skin problems and hair loss.
Beta-sitosterol is generally well tolerated short-term but should be avoided in pregnancy and breastfeeding due to insufficient safety data. It may cause digestive upset (gas, diarrhea, constipation, nausea), reduce appetite, or rarely worsen acne.
Meds to double-check
Moderate interaction found
Before taking PalmettoGuard, double-check blood thinners and antiplatelet drugs (Moderate), diabetes medications (Moderate), aspirin and other salicylate drugs (Moderate), and drugs processed by the liver enzyme CYP1A2 (Minor). Rosemary is the source of all documented interactions here.
The bottom line
Scorecard at a glanceFully disclosed formula with clinical evidence supporting its stated purpose. Moderate medication interactions have been identified, and safety information is well characterized.
PalmettoGuard is designed for people concerned with prostate health and memory. If you take blood thinners, diabetes meds, aspirin, or any salicylate-containing drug, talk with your pharmacist before starting — rosemary's interactions are real and worth checking against your specific medications.

PalmettoGuard by Life Extension Drug Interactions
HelloPharmacist Interaction Report
PalmettoGuard by Life Extension contains rosemary leaf extract, which does interact with a number of medications.
The most serious documented interaction is Moderate severity: rosemary may increase bleeding risk if you're taking blood thinners or antiplatelet drugs like warfarin or clopidogrel. In vitro and animal work suggests rosemary inhibits platelet aggregation.
Read the full breakdown — every affected drug type, severity by severity
Rosemary also carries Moderate-severity interactions with diabetes medications (due to potential blood sugar lowering), aspirin, and other salicylate-containing drugs such as choline magnesium trisalicylate and salsalate — theoretically adding to their effects. There's also a Minor interaction: rosemary may lower levels of certain drugs processed by a liver enzyme called CYP1A2, though this hasn't been reported in humans.
We could not check Total Fatty Acids for interactions. Saw Palmetto fruit extract is listed as a blend, so its individual components are covered separately in our data.
Boron and Beta-Sitosterol have no interactions documented in our data, though that's not a guarantee none exist.
Although these interactions span 371 individual medications, the best move is to run your exact prescriptions through the checker on this page before you start.
