Can You Take Vitamins and Supplements With Statins?
Statins are the most commonly prescribed class of cholesterol-lowering medication in the United States. An estimated 47 million Americans take cholesterol medication daily and the vast majority are taking a statin, according to Yale Medicine.¹
At the same time, roughly one in three American adults takes both prescription medications and dietary supplements simultaneously, according to a study using data from the National Health and Nutrition Examination Survey (NHANES).² And a 2018 survey conducted by Wakefield Research found that nearly 40% of Americans taking both prescriptions and supplements didn't know that vitamins and supplements could affect how their medications work.³
If you take a statin, this matters. Some vitamins and supplements are generally well tolerated alongside statins. Others can change how effectively your statin works or increase the risk of side effects. The difference often comes down to whether a specific ingredient interacts with the same liver enzymes your statin depends on.
Here's what you should know.
Why Statins Are Sensitive to Supplement Interactions
To understand which supplements matter, it helps to understand how statins are processed by your body.
Most statins are broken down in the liver by a family of enzymes called cytochrome P450 (CYP450). The specific enzyme involved depends on which statin you take and that distinction is the key to understanding interaction risk.
Atorvastatin (Lipitor), simvastatin (Zocor), and lovastatin (Mevacor) are primarily metabolized by the CYP3A4 enzyme. This is important because CYP3A4 is also responsible for processing a large percentage of all prescription and over-the-counter drugs. When a supplement ingredient limits CYP3A4, it can slow down how quickly your body processes these statins, which could raise the statin concentration in your bloodstream. Higher statin levels increase the risk of side effects, including a serious muscle condition called rhabdomyolysis.⁴
Fluvastatin (Lescol) is metabolized by a different enzyme, CYP2C9, and generally has less interactions with CYP3A4 inhibitors.⁴
Pravastatin (Pravachol) and rosuvastatin (Crestor) go through minimal CYP450 metabolism, making them the statins least affected by enzyme-related supplement interactions.⁴,⁵
This means that the interaction risk between a supplement and a statin isn't universal, it depends on which statin you take. A supplement ingredient that matters for someone on atorvastatin may be less relevant for someone on rosuvastatin.
Vitamins and Supplements That Require Caution With Statins
Red Yeast Rice — Avoid Combining With Statins
Red yeast rice naturally contains a compound called monacolin K, which is chemically identical to the active ingredient in the prescription statin lovastatin. Taking red yeast rice alongside a prescribed statin would result in an unregulated double dose, and could increase the risk of muscle toxicity and liver problems.⁶
The Mayo Clinic specifically warns against combining red yeast rice with statin medications due to this overlapping mechanism.⁶ If you're already on a statin, red yeast rice supplementation is unnecessary at best and potentially dangerous at worst.
St. John's Wort — Can Reduce Statin Effectiveness
St. John's wort is an herbal supplement commonly taken for mood support and mild depression. It is also a known inducer of CYP3A4 enzymes, meaning it speeds up the metabolism of drugs processed through that pathway. For statins like atorvastatin and simvastatin, this can result in the statin being broken down too quickly, reducing its cholesterol-lowering effectiveness.⁴,⁷
If you take a CYP3A4-metabolized statin and are looking for mood support, discuss alternatives with your healthcare provider rather than adding St. John's wort to your regimen.
Turmeric (Curcumin) — Caution at High Doses
Turmeric supplements have become one of the most popular supplements in the U.S., often taken for joint support and inflammation. At high supplemental doses, curcumin (the active compound in turmeric) can inhibit CYP3A4, which could increase the blood levels of CYP3A4-metabolized statins. Curcumin also has mild antiplatelet effects, which could be relevant if you take blood thinners alongside your statin.⁷,⁸
At typical culinary doses (turmeric in food), the interaction risk is minimal. The concern applies to concentrated curcumin supplements, particularly at doses above 500mg.
High-Dose Niacin (Vitamin B3) — Increased Side Effect Risk
Niacin has a long history of use for cholesterol management and was once commonly prescribed alongside statins. However, combining high-dose niacin with statins increases the risk of myopathy (muscle damage) and rhabdomyolysis. Standard multivitamin doses of niacin (typically 16–20mg) are well below the threshold of concern, but standalone niacin supplements (often 500–2,000mg) should be discussed with your physician.⁹
Resveratrol — CYP3A4 Inhibitor
Resveratrol, commonly found in NAD+ and healthy aging supplements, is a known inhibitor of CYP3A4, CYP1A2, and CYP2C9 enzymes. For someone taking atorvastatin or simvastatin, resveratrol could slow statin metabolism and increase the drug's concentration in the bloodstream. It also has mild antiplatelet properties, which adds another layer of consideration if you take blood thinners alongside your statin.¹⁰
Quercetin — CYP3A4 and CYP2C9 Inhibitor
Quercetin, a flavonoid found in some NAD+ and antioxidant supplements, can inhibit both CYP3A4 and CYP2C9 enzymes. It can also affect drug transport proteins (such as P-glycoprotein and OATP transporters) that influence how medications move in and out of cells. This gives quercetin the potential to affect a wider range of statins than ingredients that only target CYP3A4.¹¹
Vitamins and Supplements Generally Considered Safe With Statins
Coenzyme Q10 (CoQ10)
CoQ10 is one of the most frequently discussed supplements in the context of statin use, and for good reason. Statins reduce the body's natural production of CoQ10, which has led to the hypothesis that CoQ10 depletion may contribute to the muscle aches and fatigue some statin users experience.¹²
The clinical evidence on whether CoQ10 supplementation relieves statin-related muscle symptoms is mixed. A 2025 meta-analysis of randomized controlled trials found a modest reduction in muscle symptoms in some patients, but the overall evidence remains inconclusive.¹² However, CoQ10 supplementation does not appear to interfere with statin effectiveness, and many physicians recommend it as a supportive measure.¹²,¹³
Fish Oil (Omega-3 Fatty Acids)
Fish oil is generally considered safe to take alongside statins. In fact, some research suggests that combining omega-3 fatty acids with statin therapy may provide complementary benefits for lipid profiles — statins primarily reduce LDL cholesterol, while fish oil primarily targets triglycerides.⁹
At standard supplemental doses (1,000–2,000mg of EPA/DHA daily), fish oil has not been reported to interfere with statin metabolism through CYP450 pathways.
Vitamin D
Vitamin D deficiency is common in the general population and has been studied in the context of statin use because some preliminary evidence suggests that low vitamin D levels may be associated with increased risk of statin-related muscle symptoms. Vitamin D supplementation does not appear to interfere with statin metabolism and is generally considered safe to combine.¹⁴
Magnesium
Magnesium supplementation does not have widely reported interactions with statins and is generally considered safe. However, it's best taken at a separate time from your statin to avoid any potential absorption effects.⁸
Digestive Enzymes and Probiotics
Digestive enzymes and probiotic supplements generally have minimal interaction concerns with statins. These supplements work primarily in the digestive tract and do not significantly affect the liver enzyme pathways involved in statin metabolism. One exception is bromelain (a protein-digesting enzyme from pineapple), which has mild antiplatelet properties, relevant if you also take blood thinners, but not a direct statin interaction.¹⁵
Why Your Specific Statin Matters
Not all statins carry the same interaction risk. This is a point most supplement articles miss, but it matters:
Higher interaction risk (CYP3A4-metabolized): atorvastatin (Lipitor), simvastatin (Zocor), lovastatin (Mevacor). These statins are more sensitive to supplements that inhibit or induce CYP3A4, including resveratrol, curcumin, quercetin, St. John's wort, and grapefruit.[4,5]
Moderate interaction risk (CYP2C9-metabolized): fluvastatin (Lescol). Fewer supplement ingredients target CYP2C9, but quercetin is one that does.[4,5]
Lower interaction risk (minimal CYP450 metabolism): pravastatin (Pravachol), rosuvastatin (Crestor). These statins bypass the CYP450 system for most of their metabolism, making them inherently less sensitive to enzyme-related supplement interactions.[4,5]
If you take multiple supplements and have concerns about interactions, asking your physician whether pravastatin or rosuvastatin might be appropriate for your situation is a reasonable conversation to have, though the choice of statin should always be based on your full clinical picture, not supplement compatibility alone.
What This Means for Choosing Supplements
If you take a statin, the supplement you choose matters more than most brands acknowledge. Here are a few practical principles:
Check the ingredients, not just the label claims. A supplement marketed for "joint support" might contain turmeric. An "aging" supplement might contain resveratrol and quercetin. A "natural cholesterol support" supplement might contain red yeast rice. The interaction risk lives in the ingredients, not the marketing.
Know which statin you take. The three letters that matter most are the ones on your prescription bottle. Whether you're on atorvastatin or rosuvastatin changes which supplement interactions are relevant to you.
Look for supplements that disclose interaction data. Most supplement brands don't evaluate their formulas against prescription medications or if they do, they don't publish the results. Choosing a brand that provides pharmacist-reviewed interaction information gives you a concrete starting point for the conversation with your doctor.
Talk to your pharmacist. Pharmacists are specifically trained in drug-nutrient interactions and can review your full medication and supplement list. This is exactly the kind of question they're equipped to answer and it often doesn't require a scheduled appointment.

Frequently Asked Questions
Can I take a multivitamin with my statin? Standard multivitamins at typical doses are generally safe to take with statins. However, some "multivitamin plus" formulas contain added botanical ingredients (like turmeric, ginkgo, or herbal blends) that may have interaction potential. Check the full ingredient list rather than assuming all multivitamins are the same.
Is CoQ10 safe to take with statins? CoQ10 does not appear to interfere with statin effectiveness and is one of the most commonly recommended supplements for statin users. While the evidence for its ability to relieve statin-related muscle symptoms is mixed, it is generally considered safe to combine with statin therapy.
Can I take turmeric supplements with atorvastatin? Use caution, particularly with high-dose curcumin supplements. Curcumin can inhibit CYP3A4, the enzyme responsible for metabolizing atorvastatin. Turmeric used in cooking poses minimal risk, but concentrated supplements above 500mg warrant a conversation with your physician.
Why does my statin type matter for supplement interactions? Different statins are processed by different liver enzymes. Atorvastatin, simvastatin, and lovastatin use the CYP3A4 enzyme, which is also affected by many supplement ingredients. Pravastatin and rosuvastatin bypass this enzyme system for most of their metabolism, making them less susceptible to enzyme-related interactions.
Should I stop my supplements if I start a statin? Not necessarily. Many common supplements are safe to take alongside statins. The important step is to review your specific supplements with your physician or pharmacist, especially anything containing botanical extracts, high-dose niacin, or red yeast rice.
