HelloPharmacist Scorecard of NaturLo Cholesterol by Rx Vitamins

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.

From our pharmacy team — supplement deep dive

Generated from HelloPharmacist’s pharmacist-curated databases and editorial rules · Last generated Aug 27, 2026

What’s inside

Low disclosure
Ingredient Transparency · database check
Low

Most active ingredients don't disclose an individual amount — you can't tell how much of each you're getting.

Why this rating?
  • The label discloses an exact amount for 1 of its 4 active ingredients.
  • “Phytosterol Complex” is a proprietary blend — the label gives one combined amount (1,250 mg) without saying how much of each component you get.

NaturLo Cholesterol contains four active ingredients. Beta-sitosterol is a plant sterol that may help with cholesterol and prostate health.

Red yeast rice is a fermented rice product that contains naturally occurring lovastatin, a statin-like compound. The product also includes campesterol and stigmasterol, two other plant sterols, along with a phytosterol complex (a blend of plant-derived compounds that support cholesterol management).

The powder form also contains dark chocolate flavoring and fruit sugar as inactive ingredients.

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
Moderate

Some clinical evidence supports this product's ingredients for its stated purpose, but it isn't conclusive.

Why this rating?
  • The label markets this product for: support maintenance of HDL cholesterol and triglycerides.
  • We looked for evidence on: Familial hypercholesterolemia, Coronary heart disease (CHD), Atherosclerosis, Myocardial infarction (MI), Stroke, Metabolic syndrome — and 3 related terms.
  • The strongest evidence on file: Red Yeast Rice is rated "Possibly Effective" for HIV/AIDS-related dyslipidemia (Natural Medicines).
  • Also on file: Red Yeast Rice is rated "Possibly Effective" for Myocardial infarction (MI).
  • Also on file: Beta-sitosterol is rated "Possibly Effective" for Coronary heart disease (CHD), Familial hypercholesterolemia.

Beta-sitosterol is likely effective for benign prostatic hyperplasia (enlarged prostate) and possibly effective for familial hypercholesterolemia (inherited high cholesterol) and coronary heart disease. Red yeast rice is possibly effective for HIV/AIDS-related dyslipidemia (abnormal blood fats) and myocardial infarction (heart attack) prevention.

We don't have effectiveness data on file for campesterol, stigmasterol, or the phytosterol complex as individual ingredients in this product.

The evidence, ingredient by ingredient Beta-sitosterol Red Yeast Rice

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

Beta-sitosterol is generally well tolerated short-term in adults, though the most common side effects are digestive—constipation, diarrhea, gas, indigestion, and nausea. A few people have reported worsening acne.

There's one rare case report of acute pancreatitis. Red yeast rice is also generally well tolerated, but because it acts like a statin drug, it carries statin-like risks: muscle pain and breakdown (myopathy and rhabdomyolysis) and liver damage.

Common side effects include abdominal discomfort, diarrhea, dizziness, flatulence, headache, heartburn, nausea, and in rare cases, rash or hair loss. Avoid beta-sitosterol during pregnancy and breastfeeding—there isn't enough safety data.

Red yeast rice is likely unsafe in pregnancy because of its statin-like activity, and should be avoided while breastfeeding.

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 2 matched ingredients can interact with medications — Red Yeast Rice.
  • The most serious interaction on file is rated Moderate.
  • Some involve high-stakes drug classes: immunosuppressants / transplant drugs.
  • For scale: 478 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 starting NaturLo Cholesterol, check with your pharmacist or doctor if you take other statins (cholesterol drugs), cyclosporine (an immunosuppressant), gemfibrozil (a fibrate for cholesterol), high-dose niacin, CYP3A4 inhibitors (certain drugs that slow liver metabolism), or medications that can stress the liver. These are all documented interactions with red yeast rice that carry moderate risk.

The bottom line

Scorecard at a glanceFormula with limited ingredient disclosure with some supporting evidence for its stated purpose. Moderate medication interactions have been identified, and safety information is well characterized.

NaturLo Cholesterol may help with cholesterol levels and prostate health, but red yeast rice's statin-like content means you need to check all your medications first—especially if you take other cholesterol drugs, blood pressure or heart medications, or any immunosuppressants. If you're pregnant, planning pregnancy, or breastfeeding, talk with your doctor or pharmacist before using it.

Discuss this product with your doctor or pharmacist, especially if you have liver problems or take multiple medications.

Each ingredient & the kinds of drugs it affects

For each ingredient in NaturLo Cholesterol with known interactions, here are the types of medications it can affect. Open any type for the detail — or search your exact drug in the checker above.

Red Yeast Rice6 drug types · 477 drugs

Cyclosporine (Neoral, Sandimmune)

Theoretically, taking red yeast rice in combination with cyclosporine might increase the risk of myopathy.
Red yeast rice contains varying levels of the statin drug lovastatin. Cyclosporine has been reported to increase plasma levels of lovastatin by 5- to 20-fold, resulting in reports of myopathy and rhabdomyolysis.

Likelihood Probable Evidence D
Cytochrome P450 3A4 (Cyp3A4) Inhibitors

Theoretically, drugs that inhibit the CYP3A4 enzymes might increase levels of lovastatin from red yeast rice.
Red yeast rice contains varying levels of the statin drug lovastatin, which is metabolized by CYP3A4. Combining red yeast rice with CYP3A4 inhibitors might increase serum levels of lovastatin from red yeast rice.

Likelihood Possible Evidence D
Gemfibrozil (Lopid)

Theoretically, taking red yeast rice in combination with gemfibrozil might increase the risk of rhabdomyolysis.
Red yeast rice contains varying levels of the statin drug lovastatin. Gemfibrozil has been reported to increase the risk of rhabdomyolysis when used in combination with lovastatin.

Likelihood Probable Evidence D
Hepatotoxic Drugs

Theoretically, concomitant use might increase the risk of liver damage.
Red yeast rice contains varying levels of the drug lovastatin. Lovastatin can cause liver damage in some people. Some clinical research suggests that supplements containing red yeast rice might increase liver enzyme levels in some, but not all, participants. Cases of acute hepatitis have been associated with red yeast rice. Combining it with hepatotoxic drugs might further increase this risk.

Likelihood Possible Evidence D
Hmg-Coa Reductase Inhibitors ("Statins")

Theoretically, taking red yeast rice with other statins might increase the risk of potential adverse effects.
Red yeast rice contains varying levels of the statin drug lovastatin and might result in supratherapeutic levels when used with other statins. Based on evaluation of data from the US Food and Drug Administration's adverse event reporting system (FAERS), it is recommended that red yeast rice products be avoided in people taking prescription statins.

Likelihood Probable Evidence D
Niacin

Theoretically, taking red yeast rice in combination with high-dose niacin might increase the risk of rhabdomyolysis.
Red yeast rice contains varying levels of the statin drug lovastatin and has been linked to reports of myopathy. Niacin has been reported to increase the risk of rhabdomyolysis when used in combination with lovastatin.

NaturLo Cholesterol by Rx Vitamins: Common Questions

Does NaturLo Cholesterol by Rx Vitamins interact with any medications?
Yes. Based on its ingredients, NaturLo Cholesterol has a known interaction with 477 medications. Use the checker to see how it interacts with a specific drug.
How can one product interact with so many drugs?
NaturLo Cholesterol contains 4 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.
What's red yeast rice, and why is it in a cholesterol product?
Red yeast rice is a fermented rice product that naturally contains lovastatin, a statin-like compound used to lower cholesterol. It's included here because research suggests it may help manage cholesterol levels and reduce the risk of heart attack, especially in people with HIV/AIDS-related blood fat abnormalities.
Can I take this if I'm already on a statin drug?
No—not without checking with your doctor or pharmacist first. Red yeast rice contains lovastatin, so combining it with prescription statins (like atorvastatin or simvastatin) risks serious muscle damage. This is a major concern, so don't take both without their approval.
What side effects should I watch for?
The most common are digestive—gas, diarrhea, nausea, and constipation—plus headache, dizziness, and heartburn. Rare but serious risks include muscle pain or weakness (myopathy), liver damage, or muscle breakdown (rhabdomyolysis), especially if you combine it with certain other drugs.
Is it safe during pregnancy?
No. Red yeast rice is likely unsafe during pregnancy because of its statin-like activity, and there isn't enough safety data on beta-sitosterol either. Avoid this product if you're pregnant or planning pregnancy, and talk with your doctor or pharmacist.
Can I take this if I have liver problems?
You should check with your doctor or pharmacist first. Red yeast rice can stress the liver and may increase liver enzymes, especially in people already at risk. Your healthcare provider can advise whether it's safe for your specific situation.
Why does the product say to check with a healthcare provider?
Because red yeast rice contains a statin and can interact with many medications and health conditions. Also, the lovastatin content varies between batches, so your dose isn't always predictable. A pharmacist or doctor can review your medications and health history to make sure it's right for you.
