HelloPharmacist Scorecard of Red Yeast Rice Extract by Protocol For Life Balance
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 product contains one active ingredient: organic red yeast rice. Red yeast rice is a fermented grain that naturally contains lovastatin, a compound belonging to the statin drug family—the same class used to help manage cholesterol.
Because of its statin-like activity, red yeast rice works on your body similarly to prescription statin medications. The capsule also contains vegetable polysaccharide as an inactive ingredient (a binder or filler).
Does it work?
Moderate evidence
Red yeast rice is rated possibly effective for HIV/AIDS-related dyslipidemia (abnormal cholesterol and triglyceride levels in people with HIV/AIDS) and for reducing the risk of heart attack (myocardial infarction). The evidence behind these uses is still developing, and more research is ongoing.
How safe is it?
Well-documented data
Red yeast rice is generally well tolerated, with most people experiencing no problems. The most common side effects are abdominal discomfort, diarrhea, dizziness, flatulence, headache, heartburn, and nausea.
Rare but serious adverse effects include liver damage and rhabdomyolysis (severe muscle breakdown), both likely tied to its lovastatin content. Because red yeast rice works like a statin drug, it carries similar risks and concerns.
The safety data advises against using red yeast rice during pregnancy—it's rated likely unsafe. For breastfeeding, we hold no safety data on file, so talk with your doctor or pharmacist before using it if you're nursing.
Meds to double-check
Moderate interaction found
Before taking red yeast rice, double-check with your doctor or pharmacist if you take any statin medication, drugs that inhibit the CYP3A4 liver enzyme, hepatotoxic (liver-damaging) drugs, cyclosporine, gemfibrozil, or high-dose niacin. All of these have Moderate-severity interactions with the lovastatin in this product.
The bottom line
Scorecard at a glanceFully disclosed formula with some supporting evidence for its stated purpose. Moderate medication interactions have been identified, and safety information is well characterized.
Red yeast rice may be worth considering if you're looking for a statin-like supplement and your doctor approves, especially for HIV-related cholesterol concerns or heart health. However, because it contains a real statin drug (lovastatin) and interacts with dozens of medication types, you'll need to clear it with your doctor or pharmacist first—particularly if you take any cholesterol medication, a liver-affecting drug, or anything that affects how your body metabolizes statins.
It's not safe in pregnancy. Have your full medication list handy when you decide.

Red Yeast Rice Extract by Protocol For Life Balance Drug Interactions
HelloPharmacist Interaction Report
Red Yeast Rice Extract by Protocol For Life Balance interacts with medications through its lovastatin content, a statin drug naturally present in red yeast rice.
The most serious interactions are Moderate severity and involve six drug types: other statins (which might increase adverse effects when combined), drugs that inhibit the liver enzyme CYP3A4 (which could raise lovastatin levels), hepatotoxic drugs (which might increase liver damage risk), cyclosporine (which can raise lovastatin levels significantly and cause muscle damage), gemfibrozil (which may raise rhabdomyolysis risk), and high-dose niacin (which may increase rhabdomyolysis risk—a serious muscle breakdown condition).
Read the full breakdown — every affected drug type, severity by severity
Although no interactions are documented for some medication types, the lovastatin in this product can interact with a wide range of drugs. Altogether, these interactions span 478 individual medications.
Before you start red yeast rice, check your exact medications with the search tool on this page. If you take any statin, a liver-toxic drug, or anything that affects how your liver processes lovastatin, talk with your doctor or pharmacist before adding this supplement.

For each ingredient in Red Yeast Rice Extract 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.
