What is Red Yeast Rice?
Red yeast rice is a type of fermented rice produced using specific strains of mold, such as Monascus ruber or Monascus purpureus. It has been used in traditional Chinese medicine for centuries due to its health-promoting properties.
This food contains monacolin K, a compound identical to the active ingredient found in prescription cholesterol-lowering drugs like lovastatin.
Scientific studies have also highlighted other potential benefits, including reducing cancer cell growth and improving insulin sensitivity and blood sugar levels.
Today, red yeast rice is commonly available as an over-the-counter supplement, marketed for its potential to help manage cholesterol levels and support overall health.
The Main Potential Benefits of Red Yeast Rice
- Improving Heart Health: Red yeast rice may help manage cholesterol levels, potentially reducing the risk of cardiovascular diseases.
- Addressing Metabolic Syndrome: It may have a positive impact on metabolic syndrome, which includes conditions like high blood pressure, obesity, and insulin resistance.
- Decreasing Inflammation: Emerging evidence suggests that red yeast rice could help reduce inflammation, contributing to overall better health.
May Promote Heart Health
Heart disease is a serious condition affecting millions worldwide and is responsible for an estimated 31.5% of deaths globally. High cholesterol is a significant risk factor, as it can lead to the narrowing and hardening of arteries, increasing the risk of heart attack and stroke.
Red yeast rice is commonly used as a natural remedy to help reduce cholesterol levels and support heart health. It may have fewer adverse side effects compared to prescription medications used for treating high cholesterol.
A review of 21 studies found that red yeast rice was effective in lowering total and LDL (bad) cholesterol levels, as well as reducing triglycerides and blood pressure, especially when combined with statins.
Additionally, the monacolin K in red yeast rice may help improve endothelial function—the flexibility and adaptability of blood vessels—which is crucial for maintaining vascular and cardiac health.
Red Yeast Rice May Reduce Inflammation
Inflammation is a normal immune response intended to protect your body from acute infections and foreign invaders. However, chronic inflammation is believed to contribute to various long-term diseases, such as diabetes, cancer, and heart disease.
Scientific studies suggest that red yeast rice supplementation may help reduce inflammation and support better long-term health. For instance, a study involving 50 individuals with metabolic syndrome found that an 8-week regimen of a supplement containing red yeast rice and olive extract reduced oxidative stress—an important factor in chronic inflammation—by up to 20%.
Similarly, research on rats with kidney damage demonstrated that red yeast extract lowered levels of specific proteins associated with inflammation.
However, further comprehensive studies with larger sample sizes are needed to draw more definitive conclusions.
May Have Anti-Cancer Properties
Current research on the anti-cancer effects of red yeast rice is primarily limited to animal and in vitro studies. However, some evidence suggests it may help inhibit the growth and spread of cancer cells.
For example, one study found that administering red yeast rice powder to mice with prostate cancer significantly reduced tumor volume compared to a control group.
Despite these promising findings, more research is needed to assess the effects of red yeast rice on various cancers in humans. Specifically, further studies are necessary to understand how its potential anti-cancer properties might impact the general population.
May Help Treat Metabolic Syndrome
Metabolic syndrome is a collection of conditions that increase the risk of chronic diseases such as heart disease, diabetes, and stroke. Key criteria for metabolic syndrome include high blood pressure, excess body fat, elevated blood sugar levels, and abnormal cholesterol or triglyceride levels.
Several studies suggest that red yeast rice may help address some of these risk factors and could serve as a natural aid in preventing metabolic syndrome. Notably, one of its most well-documented effects is its ability to lower cholesterol levels. Research indicates that red yeast rice can effectively reduce both total and LDL (bad) cholesterol levels, which may contribute to better management of metabolic syndrome.
How to Take Red Yeast Rice
Red yeast rice supplements come in various forms, each with its own characteristics. Here’s a look at the most common types:
- Capsules: One of the most popular forms, red yeast rice capsules are convenient and easy to take. They come in various dosages, typically ranging from 600 to 1,200 milligrams per capsule. Capsules offer precise dosing and are often preferred for their ease of use.
- Tablets: Similar to capsules, red yeast rice tablets are another common form. They also come in different strengths and are easy to incorporate into a daily routine. Tablets may sometimes include additional ingredients aimed at enhancing their effectiveness or ease of digestion.
- Powder: Red yeast rice is also available in powdered form, which can be mixed into beverages or foods. This form is less common but may be preferred by individuals who have difficulty swallowing capsules or tablets. Dosage can be more flexible with powder, allowing for adjustments based on individual needs.
- Softgels: Softgel supplements are similar to capsules but have a gelatinous outer layer. They may be easier to swallow for some people and can offer quicker absorption of the red yeast rice extract.
- Blends: Some supplements combine red yeast rice with other beneficial ingredients, such as coenzyme Q10, olive extract, or other herbs. These blends are designed to provide additional health benefits and may be marketed as more comprehensive heart health or cholesterol support products.
Each type of supplement has its own advantages and can be chosen based on personal preference and convenience. Always choose a high-quality product from a reputable manufacturer and follow the dosage instructions provided.

Contraindications of Red Yeast Rice
Side Effects
Despite the potential benefits of red yeast rice, it may have some side effects, making it important to consult with a healthcare professional before starting this supplement.
Common side effects include gastrointestinal issues such as bloating, gas, and stomach pain. In more severe cases, red yeast rice can cause muscle problems, liver toxicity, and allergic reactions, similar to those associated with prescription cholesterol-lowering medications.
Due to limited research on the long-term safety of red yeast rice, it is not recommended for pregnant or breastfeeding women. If you experience adverse symptoms after taking red yeast rice, consider reducing the dosage or discontinuing use and consult a healthcare professional.
Citrinin Formation
Improperly grown red yeast rice may contain citrinin, a byproduct of certain molds. Citrinin is a mycotoxin that can cause kidney failure in animals and may affect gene expression in humans.
Legal Status
Monacolin K, the active compound in red yeast rice, is also used in statins and other cholesterol-lowering medications. According to the U.S. Food and Drug Administration (FDA), products containing monacolin K should be treated as medicinal products and are subject to stricter regulations than standard over-the-counter supplements.
While red yeast rice supplements are legal, they should only contain trace amounts of monacolin K. Since only the amount of red yeast rice is typically listed on the label, it is difficult for consumers to know the exact amount of monacolin K present.
Medication Interactions
Red yeast rice contains monacolin K, which is similar to the active ingredient in statins. Therefore, it should not be taken concurrently with statins unless specifically advised by a healthcare professional.
Red yeast rice may also interact with the same medications as statins, including other cholesterol-lowering drugs, certain antibiotics, antidepressants, antifungals, and antiretrovirals. If you are taking any of these medications, consult with a healthcare professional before starting red yeast rice supplements.
