HelloPharmacist Scorecard of Red Yeast Rice by Adaptogen Research
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 supplement contains one active ingredient: organic red yeast rice, which is fermented rice that naturally contains lovastatin — the same statin drug found in prescription cholesterol medications. Red yeast rice works in your body much like a statin would, lowering cholesterol through the same mechanism.
The capsule also includes inactive ingredients (cellulose and L-leucine) that help form and fill the capsule.
Does it work?
Moderate evidence
Red yeast rice is rated possibly effective for HIV/AIDS-related dyslipidemia (abnormal cholesterol and triglycerides in people with HIV) and possibly effective at reducing the risk of heart attack (myocardial infarction). The evidence supports its use for these conditions, though it's not considered definitively proven.
Remember that because it acts like a statin, its benefits come with statin-like risks.
How safe is it?
Well-documented data
Red yeast rice is generally well tolerated, but it carries real risks because it works like a statin drug. The most common side effects are abdominal discomfort, diarrhea, dizziness, flatulence, headache, heartburn, and nausea.
Rare but serious effects include liver damage (hepatotoxicity) and muscle breakdown (rhabdomyolysis), both linked to the lovastatin content — and contaminated products can cause kidney damage. A small number of trial participants reported mild rash, itching, or in rare cases hair loss.
Red yeast rice is rated likely unsafe during pregnancy because of its statin-like effects, and there isn't enough safety data to recommend it during breastfeeding — talk with your doctor or pharmacist before using it if you're pregnant or nursing.
Meds to double-check
Moderate interaction found
Before taking red yeast rice, check with your doctor or pharmacist if you take cyclosporine (Neoral, Sandimmune), other statin drugs, gemfibrozil (Lopid), high-dose niacin, drugs that inhibit CYP3A4 enzymes, or any medications that can damage the liver. No interactions are documented for the inactive ingredients we could check.
The bottom line
Scorecard at a glanceFully disclosed formula with some supporting evidence behind its ingredients' uses. Moderate medication interactions have been identified, and safety information is well characterized.
Red yeast Rice might be right for you if you're looking for a natural approach to cholesterol or heart health and your doctor agrees — but because it contains a prescription-strength statin drug and interacts with many medications, it's not a simple supplement. If you take any prescription drugs, especially cholesterol medications, immunosuppressants, or heart drugs, you need to clear this with your doctor or pharmacist first.
This isn't something to start on your own.

Red Yeast Rice by Adaptogen Research Drug Interactions
HelloPharmacist Interaction Report
Red Yeast Rice by Adaptogen Research interacts with medications through its lovastatin content, a statin drug naturally present in the supplement.
The most serious concern is with cyclosporine (an immunosuppressant), which can raise lovastatin levels dramatically and cause muscle breakdown (myopathy) or rhabdomyolysis — a severe condition where muscle tissue breaks down and damages the kidneys.
Read the full breakdown — every affected drug type, severity by severity
You'll also want to avoid combining red yeast rice with other statins (cholesterol drugs like atorvastatin or simvastatin), as doubling up on statin activity increases the risk of muscle damage. Gemfibrozil (Lopid), a fibrate used for cholesterol, and high-dose niacin (vitamin B3) both carry a documented risk of rhabdomyolysis when mixed with lovastatin.
CYP3A4 inhibitors — drugs that slow how your body processes the lovastatin in red yeast rice — may raise lovastatin levels unexpectedly. Hepatotoxic drugs (medications that can harm the liver) may increase that risk further when combined with red yeast rice.
Because red yeast rice contains a drug-like active ingredient and product quality varies widely, you should check your exact medications with your doctor or pharmacist before starting. Altogether, these interactions span 478 individual medications.

For each ingredient in Red Yeast Rice 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.
organic Red Yeast Rice
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.
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.
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.
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.
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.
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.
