HelloPharmacist Scorecard of Cholesterol Health by DC
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
Cholesterol Health contains 2 active ingredients. Red Yeast Rice Extract is a fermented rice product that works like a statin drug—it contains lovastatin, which lowers cholesterol by blocking an enzyme your liver needs to make it.
Soy Germ Concentrate comes from soy plants and contains compounds called isoflavones that research suggests may help with cholesterol, blood sugar, and blood pressure. The capsule also holds inactive ingredients: gelatin, vegetable magnesium stearate, and silica, which are standard binders and flow agents.
Does it work?
Moderate evidence
Red Yeast Rice is possibly effective for heart attack prevention and for managing abnormal cholesterol in people with HIV/AIDS, according to the data we have. Soy Germ Concentrate is possibly effective for diabetes, high cholesterol, weak bones (osteoporosis), and high blood pressure.
Keep in mind that "possibly effective" means the evidence is promising but not yet conclusive—talk with your doctor about whether it makes sense for your specific situation.
How safe is it?
Well-documented data
Red Yeast Rice is generally well tolerated, but it works like a statin and carries statin risks. The most common side effects are abdominal discomfort, diarrhea, dizziness, flatulence, headache, heartburn, muscle pain (myopathy), and nausea.
Rare but serious effects include liver damage and muscle breakdown (rhabdomyolysis), especially if the product is contaminated. The safety data advises against it during pregnancy because of its statin-like activity.
We hold no lactation data for red yeast rice. Soy is well tolerated in normal food amounts.
Soy Germ Concentrate can cause bloating, constipation, diarrhea, and nausea, and allergic reactions (rash, itching) are possible in sensitive people. For pregnancy, soy foods in normal amounts are likely safe, but high-dose concentrated supplements carry uncertain risks—talk with your doctor for personalized advice.
Soy foods are commonly eaten while breastfeeding and are likely safe, though concentrated supplements haven't been well studied.
Meds to double-check
Major interaction found
Before taking this, double-check if you're on monoamine oxidase inhibitors (MAOIs)—a Major-severity interaction with both ingredients. Next, check for moderate interactions with other statins or cholesterol drugs, CYP3A4 inhibitors (certain antifungals, some antibiotics, some immunosuppressants), cyclosporine, gemfibrozil, high-dose niacin, drugs that can damage the liver, blood pressure medications, estrogen replacement therapy, diabetes drugs, diuretics, caffeine in supplement form, warfarin (a blood thinner), and levothyroxine (thyroid hormone).
If you take any of these, run them through the medication checker below.
The bottom line
Scorecard at a glanceFully disclosed formula with some supporting evidence for its stated purpose. Major medication interactions have been identified, and safety information is well characterized.
This product is designed for people managing cholesterol, and the research suggests both ingredients have potential. However, because red yeast rice acts like a statin and interacts with many medications—especially blood pressure drugs, other statins, certain antibiotics and antifungals, and antidepressants—you need to check your full medication list with your pharmacist or doctor first.
If you take cyclosporine, gemfibrozil, high-dose niacin, or MAOIs, this product is not for you.

Cholesterol Health by DC Drug Interactions
HelloPharmacist Interaction Report
Cholesterol Health by DC contains two active ingredients that together interact with a substantial number of medications, and you'll want to check your prescriptions carefully before starting it.
Read the full breakdown — every affected drug type, severity by severity
Red Yeast Rice Extract is the bigger concern here. It contains the statin drug lovastatin in varying amounts, which means it carries statin-like risks.
The most serious interaction is with monoamine oxidase inhibitors (MAOIs)—antidepressants used for depression—because of a risk of high blood pressure crisis. Red yeast rice also interacts moderately with other statins (cholesterol drugs), drugs that inhibit liver enzymes called CYP3A4 inhibitors, cyclosporine (an immunosuppressant), gemfibrozil (a cholesterol medication), niacin (a B vitamin supplement), hepatotoxic drugs (drugs that can damage the liver), and some others.
Soy Germ Concentrate adds several more interactions. Its main concern is also with MAOIs due to tyramine content, though the soy interaction is listed as Major severity.
Soy can also interact moderately with blood pressure medications, estrogen replacement therapy, diabetes drugs, diuretics (water pills), caffeine, warfarin (a blood thinner), and levothyroxine (thyroid hormone).
Each ingredient was checked against our data. Altogether, these interactions span 927 individual medications.

For each ingredient in Cholesterol Health 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.
Soy Germ Concentrate
Monoamine Oxidase Inhibitors (Maois)
Taking soy products containing high amounts of tyramine along with MAOIs can increase the risk of hypertensive crisis.
Fermented soy products such as tofu and soy sauce contain tyramine, a naturally occurring chemical that affects blood pressure regulation. The metabolism of tyramine is decreased by MAOIs. Consuming more than 6 mg of tyramine while taking an MAOI can increase the risk of hypertensive crisis. The amount of tyramine in fermented soy products is usually less than 0.6 mg per serving; however, there can be significant variation depending on the specific product used, storage conditions, and length of storage. Storing one brand of tofu for a week can increase tyramine content from 0.23 mg to 4.8 mg per serving. Advise patients taking MAOIs to avoid fermented soy products that contain high amounts of tyramine.
Antidiabetes Drugs
Soy can lower blood glucose and have additive effects with antidiabetes drugs.
Clinical research shows that whole soy diets and soy-based meals reduce fasting glucose levels in diabetic and non-diabetic individuals. Also, individuals following a soy-based meal replacement plan seem to require lower doses of sulfonylureas and metformin to manage blood glucose levels when compared with individuals following a diet plan recommended by the American Diabetes Association.
Antihypertensive Drugs
Theoretically soy protein may have additive effects with antihypertensive drugs and increase the risk of hypotension.
Although some contradictory research exists, most clinical evidence suggests that consuming soy protein modestly reduces systolic and diastolic blood pressure in individuals with prehypertension or hypertension.
Caffeine
Theoretically, soy might reduce the clearance of caffeine.
Soy contains genistein. Taking genistein 1 gram daily for 14 days seems to inhibit caffeine clearance and metabolism in healthy females. This effect has been attributed to inhibition of the cytochrome P450 1A2 (CYP1A2) enzyme, which is involved in caffeine metabolism. It is unclear if this effect occurs with the lower amounts of genistein found in soy.
Diuretic Drugs
Theoretically, soy might have additive effects when used with diuretic drugs.
Animal research suggests that genistein, a soy isoflavone, increases diuresis within 6 hours of subcutaneous administration in rats. The effects seem to be similar to those of furosemide. This effect has not been reported in humans.
Estrogens
Theoretically, soy might competitively inhibit the effects of estrogen replacement therapy.
Soy contains phytoestrogens and has been shown to have estrogenic activity in some patients. Although this has not been demonstrated in humans, theoretically, concomitant use of soy with estrogen replacement therapy might reduce the effects of the estrogen replacement therapy.
Levothyroxine (Synthroid, Others)
Soy products might reduce the absorption of levothyroxine in some patients.
Preliminary clinical research and a case report suggest that soy-based formulas inhibit the absorption of levothyroxine in infants with congenital hypothyroidism. A levothyroxine dosage increase may be needed for infants with congenital hypothyroidism while using soy-based formulas, and the dose may need to be reduced when soy-based formulas are no longer administered. However, in postmenopausal adults, clinical research shows that taking a single dose of soy extract containing isoflavones 60 mg along with levothyroxine does not affect the oral bioavailability of levothyroxine.
Progesterone
Theoretically, combining soy isoflavones with transdermal progesterone may worsen bone density.
Clinical research suggests that significant bone loss may occur in females with osteoporosis who receive a combination of transdermal progesterone with soy milk containing isoflavones when compared with placebo, soy milk alone, or progesterone alone.
Tamoxifen (Nolvadex)
Theoretically, estrogenic soy isoflavones might alter the effects of tamoxifen.
Laboratory research suggests that genistein and daidzen, isoflavones from soy, can antagonize the antitumor effects of tamoxifen under some circumstances; however, soy isoflavones might have different effects when used at different doses. A relatively low in vitro concentration of soy isoflavones such as 1 microM/L seems to interfere with tamoxifen, whereas high in vitro concentrations such as those >10 microM/L might actually enhance tamoxifen effects. People on a high-soy diet have soy isoflavones levels ranging from 0.1-6 microM/L. Until more is known, advise patients taking tamoxifen to avoid therapeutic use of soy products.
Warfarin (Coumadin)
Theoretically, soy might interfere with the effects of warfarin.
Soy milk has been reported to decrease the international normalized ratio (INR) in a patient taking warfarin. The mechanism of this interaction is not known. However, animal and in vitro research suggests that soy may also inhibit platelet aggregation. Dosing adjustments for warfarin may be necessary.
Antibiotic Drugs
Theoretically, antibiotics may decrease the activity of soy isoflavones.
Intestinal bacteria are responsible in part for converting soy isoflavones into their active forms. Antibiotics may decrease the amount of intestinal bacteria and decrease its ability to convert isoflavones.
Cytochrome P450 2C9 (Cyp2C9) Substrates
Soy might modestly induce CYP2C9 enzymes. However, this effect does not seem to be clinically significant.
In vitro research suggests that an unhydrolyzed soy extract might induce CYP2C9. However, the significance of this interaction is likely minimal. In healthy females taking a specific extract of soy (Genistein Soy Complex, Source Naturals), blood levels of losartan, a CYP2C9 substrate, were not significantly affected.
Red Yeast Rice Extract
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.
