HelloPharmacist Scorecard of Phytosterol Complex With Beta Sitosterol by Sundown Naturals
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
Low disclosure
This product contains 3 active ingredients: beta-sitosterol, campesterol, and stigmasterol—all plant-derived sterols (phytosterols) that work similarly in the body. Beta-sitosterol is the primary one and the most studied.
The remaining inactive ingredients are vegetable oil, gelatin, vegetable glycerin, soybean oil, citrus pectin, and titanium dioxide.
Does it work?
Moderate evidence
Beta-sitosterol is likely effective for benign prostatic hyperplasia (BPH)—enlarged prostate—and possibly effective for familial hypercholesterolemia (inherited high cholesterol) and coronary heart disease. We don't hold effectiveness data for campesterol or stigmasterol individually.
How safe is it?
Well-documented data
Beta-sitosterol is generally well tolerated when taken short-term. The most common side effects are constipation, diarrhea, gas, indigestion, and nausea.
There's also a report that beta-sitosterol can worsen acne. One case report linked it to acute pancreatitis, though symptoms resolved when the person stopped taking it.
The safety data advises against using beta-sitosterol during pregnancy or while breastfeeding because there isn't enough information. Talk with your doctor or pharmacist about whether this product is right for you if you're pregnant, planning to become pregnant, or nursing.
Meds to double-check
No known interactions
No interactions are documented for the ingredients we could check. That said, use the search tool on this page to confirm your specific medications aren't affected.
The bottom line
Scorecard at a glanceFormula with limited ingredient disclosure with some supporting evidence for its stated purpose. No medication interactions are currently documented, and safety information is well characterized.
If you have an enlarged prostate or high cholesterol and want to explore a plant-sterol supplement, beta-sitosterol has some research behind it. Watch for digestive upset and let your doctor know you're taking it, especially if you're pregnant, breastfeeding, or have a history of pancreatitis.
Chat with your pharmacist or doctor before starting.
