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 3 of its 3 active ingredients.
  • No proprietary blends here — you can verify the dose of every single component.

This formula has 3 active ingredients working to support cholesterol. Policosanol is a plant compound studied for its cholesterol and blood circulation effects.

Plant sterols are naturally occurring compounds found in foods that help block cholesterol absorption in your gut. Odor-controlled garlic is garlic extract modified to reduce the classic smell while keeping the active components.

The product also contains several inactive ingredients—binders, fillers, and capsule materials like microcrystalline cellulose, magnesium stearate, and silica—to hold the formula together and make it easy to swallow.

Does it work?

Strong 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
Strong

Clinical evidence supports at least one of this product's ingredients for its stated purpose.

Why this rating?
  • The label markets this product for: Help reduce risk of coronary heart disease.
  • We looked for evidence on: Coronary heart disease (CHD), Cardiovascular disease (CVD), Atherosclerosis, Hypercholesterolemia, Familial hypercholesterolemia, Myocardial infarction (MI) — and 4 related terms.
  • The strongest evidence on file: Policosanol is rated "Likely Effective" for Intermittent claudication (Natural Medicines).
  • Also on file: Plant Sterols is rated "Likely Effective" for Familial hypercholesterolemia, Hypercholesterolemia.
  • Also on file: Garlic is rated "Possibly Effective" for Atherosclerosis, Hypertension.

Plant sterols are likely effective for high cholesterol (hypercholesterolemia) and familial high cholesterol, and possibly effective for heart disease. Policosanol shows likely effectiveness for a specific circulation condition called intermittent claudication, but the evidence for heart disease and familial high cholesterol isn't yet established in our data.

Garlic is possibly effective for high blood pressure, diabetes, fatty liver disease, periodontitis (gum disease), and atherosclerosis (clogged arteries).

The evidence, ingredient by ingredient Policosanol Plant Sterols Garlic

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 3 of the 3 matched ingredients.
  • Pregnancy & breastfeeding safety ratings cover 2 of 3.
  • General safety write-ups exist for 3 of 3.
  • Remember: this measures how much safety information exists. Thin data is not the same as being safe.

Policosanol is generally well tolerated, though a small number of trial participants reported headache, dizziness, sleepiness, upset stomach, insomnia, or rash. Weight loss has occurred but is uncommon at typical doses.

The safety data advises against use during pregnancy and breastfeeding. Plant sterols are generally well tolerated at normal amounts; concentrated supplements during pregnancy and breastfeeding haven't been well studied, so caution is advised and you should talk with your doctor.

Garlic is generally well tolerated as food but supplements may cause stomach upset, gas, bad breath, or nausea. Rare cases of increased bleeding risk have been reported.

Food amounts are likely fine during pregnancy and breastfeeding, but concentrated supplement doses aren't well studied.

Odor-controlled garlic12 drug types · 989 drugs

Anticoagulant/Antiplatelet Drugs

Garlic may have antiplatelet effects and may increase the risk of bleeding if used with anticoagulant or antiplatelet drugs.
Raw garlic and a variety of garlic extracts have antiplatelet activity and can increase prothrombin time.

Likelihood Possible Evidence D
Antidiabetes Drugs

Theoretically, taking garlic with antidiabetes drugs might increase the risk of hypoglycemia.
Clinical research suggests that garlic and garlic extract lower blood glucose levels in healthy and diabetic individuals.

Likelihood Possible Evidence B
Antihypertensive Drugs

Theoretically, taking garlic with antihypertensive drugs might increase the risk of hypotension.
In human research, both garlic and garlic extracts have blood pressure-lowering effects.

Likelihood Possible Evidence D
Atazanavir (Reyataz)

Theoretically, garlic might decrease levels and effects of atazanavir.
In a case report, a patient consuming six stir-fried garlic cloves three times weekly developed suboptimal atazanavir levels and increases in HIV viral load. While the exact cause of this interaction is unclear, there is speculation that garlic might decrease the intestinal absorption of atazanavir or increase its metabolism by inducing cytochrome P450 3A4 (CYP3A4). Until more is known, advise patients not to consume large amounts of garlic while taking atazanavir.

Likelihood Possible Evidence D
Cytochrome P450 2E1 (Cyp2E1) Substrates

Garlic might increase levels of drugs metabolized by CYP2E1.
Clinical research suggests garlic oil can inhibit the activity of CYP2E1 by 39%. Use garlic oil cautiously in patients taking drugs metabolized by these enzymes.

Likelihood Probable Evidence B
Cytochrome P450 3A4 (Cyp3A4) Substrates

Theoretically, garlic products containing allicin might induce intestinal CYP3A4 and inhibit hepatic CYP3A4. This may increase or decrease levels of drugs metabolized by CYP3A4.
Some human research suggests that garlic may induce INTESTINAL CYP3A4, reducing levels of drugs metabolized by this enzyme. This is primarily based on a study showing that taking a specific allicin-containing garlic product (GarliPure Maximum Allicin Formula, Natrol Inc.) twice daily for 3 days reduces saquinavir levels by approximately 50%. It is speculated that the allicin constituent induced CYP3A4 in the gut mucosa. Another study shows that giving docetaxel intravenously, bypassing the CYP3A4 enzymes in the gut mucosa, along with the same specific garlic product for 12 consecutive days, does not affect docetaxel levels. Conversely, there is concern that garlic may inhibit HEPATIC CYP3A4. In a single case report, increased tacrolimus levels and liver injury occurred in a liver transplant patient after taking a specific garlic supplement (Garlicin Cardio, Nature's Way) at up to three times the manufacturer recommended dose for 7 days. Several other studies have evaluated the impact of other garlic formulations on CYP3A4 substrates and have found no effect. Most of the products in these studies provided little or no allicin.

Likelihood Possible Evidence B
Isoniazid

Theoretically, garlic might decrease levels of isoniazid.
Animal research suggests that an aqueous extract of garlic reduces isoniazid levels by about 65%. Garlic reduced the maximum concentration (Cmax) and area under the curve (AUC), but not the half-life, of isoniazid. This suggests that garlic extract might inhibit isoniazid absorption across the intestinal mucosa; however, the exact mechanism of this potential interaction is not known.

Likelihood Possible Evidence D
Protease Inhibitors (Pis)

Theoretically, garlic products containing allicin might decrease levels of PIs.
Protease inhibitors are metabolized by cytochrome P450 3A4 (CYP3A4) isoenzymes. There is concern that garlic products containing allicin might induce intestinal CYP3A4, reducing plasma levels of protease inhibitors. This is primarily based on a study showing that taking a specific garlic product (GarliPure Maximum Allicin Formula, Natrol Inc.) twice daily for 3 days reduces levels of saquinavir, a PI, by approximately 50%. It is speculated that the allicin constituent induce CYP3A4 in the gut mucosa. Several studies have evaluated the impact of other garlic formulations on CYP3A4 substrates and have found no effect. Most of the products in these studies provided little or no allicin.

Likelihood Possible Evidence B
Saquinavir (Fortovase, Invirase)

Theoretically, garlic containing allicin might decrease levels of saquinavir.
Saquinavir is a substrate of cytochrome P450 3A4 (CYP3A4) isoenzymes. There is concern that garlic products containing allicin might induce intestinal CYP3A4 and cause subtherapeutic levels of saquinavir. This is primarily based on a pharmacokinetic study showing that taking a specific garlic product (GarliPure Maximum Allicin Formula, Natrol Inc.) twice daily for 3 days reduces saquinavir levels by approximately 50%. It is speculated that the allicin constituent induces CYP3A4 in the gut mucosa. Several pharmacokinetic studies have evaluated the impact of other garlic formulations on CYP3A4 substrates and have found no effect. Most of the products in these studies provided little or no allicin. Until more is known about this potential interaction, use garlic containing allicin cautiously in patients taking saquinavir.

Likelihood Possible Evidence B
Sofosbuvir (Sovaldi)

Theoretically, taking garlic with sofosbuvir might decrease its effectiveness.
Animal research in rats shows that giving aged garlic extract 120 mg/kg orally daily for 14 days decreases the area under the concentration time curve (AUC) after a single sofosbuvir dose of 40 mg/kg by 36%, increases the clearance by 63%, and decreases the plasma concentrations at 1 and 8 hours by 35% and 58%, respectively. This interaction is hypothesized to be due to induction of intestinal P-glycoprotein expression by garlic.

Likelihood Possible Evidence D
Tacrolimus (Prograf)

Theoretically, garlic might increase levels of tacrolimus.
In one case report, a liver transplant patient taking tacrolimus experienced increased tacrolimus levels and liver injury after taking a specific garlic supplement (Garlicin Cardio, Nature's Way) at up to three times the manufacturer recommended dose for 7 days. It is speculated that garlic inhibited hepatic cytochrome P450 3A4 (CYP3A4), which increased plasma levels of tacrolimus.

Likelihood Possible Evidence B
Warfarin (Coumadin)

Theoretically, garlic might increase the risk of bleeding with warfarin.
Raw garlic and a variety of garlic extracts have antiplatelet activity and can increase prothrombin time. In addition, there is a report of two patients who experienced an increase in a previously stabilized international normalized ratio (INR) with concomitant garlic and warfarin use. However, this report has been subsequently debated due to limited clinical information. Other clinical studies have not identified an effect of garlic on INR, warfarin pharmacokinetics, or bleeding risk. More evidence is needed to determine the safety of using garlic with warfarin.

Likelihood Possible Evidence D
Odor-controlled garlic full monograph & interactions

Policosanol6 drug types · 242 drugs

Anticoagulant/Antiplatelet Drugs

Theoretically, taking policosanol with other antiplatelet or anticoagulant drugs might increase the risk of bruising and bleeding.
Some clinical research shows that taking policosanol 10-50 mg daily for 7-15 days can inhibit platelet aggregation in healthy patients. Although, one clinical trial shows that taking policosanol 10 mg twice daily for 2 weeks prior to warfarin dosing does not affect warfarin pharmacokinetics or warfarin response. Furthermore, a study in patients undergoing percutaneous coronary intervention with a drug-eluting stent found that taking policosanol 40 mg plus clopidogrel and aspirin daily for 30 days modestly reduced the risk for minor bleeding events when compared with taking clopidogrel and aspirin alone. Until more is known, use with caution.

Likelihood Possible Evidence B
Antidiabetes Drugs

Theoretically, policosanol might have additive effects with antidiabetes drugs and increase the risk of hypoglycemia.
Clinical research shows that policosanol can lower blood glucose levels.

Likelihood Possible Evidence B
Beta-Blockers

Concomitant use of policosanol with beta-blockers can cause additive blood pressure-lowering effects.
Clinical research shows that policosanol 5 mg daily can have additive blood pressure-lowering effects in patients with hypertension who are taking beta-blockers. Also, animal research shows that policosanol can increase the blood-pressure lowering effects of propranolol.

Likelihood Probable Evidence A
Nitroprusside (Nitropress)

Theoretically, concomitant use of policosanol with nitroprusside might cause additive blood pressure-lowering effects.
Animal research shows that taking policosanol along with nitroprusside can increase the blood pressure-lowering effects of nitroprusside.

Likelihood Possible Evidence D
Propranolol (Inderal)

Animal research shows that taking policosanol along with propranolol can increase the blood pressure-lowering effects of propranolol.

Likelihood Possible Evidence D
Warfarin (Coumadin)

Theoretically, taking policosanol with warfarin might increase the risk of bruising and bleeding.
Some clinical research shows that taking policosanol 10-50 mg daily for 7-15 days can inhibit platelet aggregation in healthy patients. However, one clinical trial shows that taking policosanol 10 mg twice daily for 2 weeks prior to warfarin dosing does not affect warfarin pharmacokinetics or warfarin response.

Plant Sterol Cholesterol Control Formula by Windmill Rx Premium Vitamins: Common Questions

Does Plant Sterol Cholesterol Control Formula by Windmill Rx Premium Vitamins interact with any medications?
Yes. Based on its ingredients, Plant Sterol Cholesterol Control Formula has a known interaction with 993 medications. Use the checker to see how it interacts with a specific drug.
How can one product interact with so many drugs?
Plant Sterol Cholesterol Control Formula contains 3 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.
Is this safe during pregnancy or breastfeeding?
The safety data advises against policosanol during pregnancy and breastfeeding due to insufficient safety information. Plant sterols and garlic at food amounts are likely fine, but concentrated supplement doses during pregnancy and breastfeeding haven't been well studied. Talk with your doctor or pharmacist before using this product if you're pregnant or breastfeeding.
What side effects might I notice?
Policosanol may cause headache, dizziness, upset stomach, or insomnia in a small number of people. Garlic commonly causes gas, bloating, bad breath, or nausea. Rare cases of rash or increased bleeding risk have been reported with these ingredients. Most people tolerate them without problems.
Does this actually lower cholesterol?
Plant sterols are likely effective for high cholesterol—they work by blocking cholesterol absorption in your gut. Policosanol shows strong evidence for circulation problems but the cholesterol evidence isn't yet established in our data. Garlic may help with blood pressure and metabolic health but the cholesterol evidence isn't clear.
Why does it say 'odor-controlled' garlic?
Regular garlic supplements can leave you with bad breath and body odor. This formula uses garlic extract that's been processed to reduce that smell while keeping the active compounds that do the work.
What are the inactive ingredients?
The inactive ingredients are standard binders and fillers—things like microcrystalline cellulose, magnesium stearate, and silica—that help form and hold the tablet together. They're not the active part of the formula.
Can I take this if I'm on a blood thinner like warfarin?
Both policosanol and garlic in this formula interact with blood thinners and may increase your bleeding risk. You must talk to your pharmacist or doctor before starting—do not take this on your own if you're on warfarin or any other blood thinner.
