HelloPharmacist Scorecard of Red Yeast Rice Complex by Bronson Laboratories
Four independent checks of what is known — a summary of the available information, not a grade of the product itself.
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
The stated purpose hasn't been mapped to our evidence data yet.
Why this rating?
- We haven't mapped this product's purpose to our evidence data yet — it'll be graded on the next content refresh.
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.
The most serious documented interaction for these ingredients is Moderate. Check your medications for a personalized result.
Why this rating?
- 2 of the 3 matched ingredients can interact with medications — Inositol Nicotinate, Red Yeast Rice.
- The most serious interaction on file is rated Moderate.
- Some involve high-stakes drug classes: anticoagulant / antiplatelet drugs; immunosuppressants / transplant drugs; diabetes medications.
- For scale: 655 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.
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.
HelloPharmacist summaryFully disclosed formula with no assessable stated purpose. Moderate medication interactions have been identified, and safety information is well characterized.
Assessment coverage: 3 of 3 active ingredients matched to our full ingredient reviews (monographs). Based on the product label dated Apr 26, 2012.
This Scorecard evaluates available label information, ingredient evidence, and known medication-safety considerations. It does not independently verify product identity, purity, potency, contamination, or manufacturing quality. How these ratings are computed

For each ingredient in Red Yeast Rice Complex with known interactions, here are the types of medications they can affect. Open any type for the detail — or search your exact drug in the checker above.
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.
Inositol Hexanicotinate
Anticoagulant/Antiplatelet Drugs
Theoretically, concomitant use of inositol nicotinate with anticoagulant or antiplatelet drugs might increase the risk of bleeding.
Inositol nicotinate has fibrinolytic effects, which may increase the risk of bleeding when used concomitantly with anticoagulant/antiplatelet drugs.
Antidiabetes Drugs
Theoretically, inositol nicotinate might increase blood glucose levels and may diminish the effects of antidiabetes drugs.
Inositol nicotinate is metabolized to niacin in the body. Niacin can cause hyperglycemia, abnormal glucose tolerance, and glycosuria. Increased blood glucose monitoring may be necessary, particularly early in the course of treatment.
Hmg-Coa Reductase Inhibitors ("Statins")
Theoretically, concomitant use of inositol nicotinate and statins might increase the risk of myopathy and rhabdomyolysis.
Inositol nicotinate is metabolized to niacin in the body. Some case reports have raised concerns that niacin might increase the risk of myopathy and rhabdomyolysis when combined with statins However, a significantly increased risk of myopathy has not been demonstrated in clinical trials.
Transdermal Nicotine (Nicoderm)
Theoretically, concomitant use of inositol nicotinate and transdermal nicotine might increase the risk of flushing and dizziness.
Inositol nicotinate is metabolized to niacin in the body. Inositol nicotinate and nicotine can both cause flushing and dizziness.
