What is red yeast rice and why is it so popular?
Red yeast rice is a natural product derived from the fermentation of rice by a mold called Monascus purpureus. Used for centuries in traditional Chinese medicine, it is now recognized for its effectiveness in regulating cholesterol and protecting the cardiovascular system.
Its richness in monacolines, notably monacolin K, gives it a powerful cholesterol-lowering effect, similar to that of synthetic statins. It is therefore frequently recommended as a dietary supplement to reduce LDL cholesterol levels, prevent atherosclerosis and improve cardiovascular health.
In addition to its action on cholesterol, red yeast rice contains antioxidants, phytosterols and isoflavones, which help protect cells against oxidative stress and promote metabolic balance.
What are the benefits of red yeast rice for cardiovascular health and metabolism?
One of the main benefits of red yeast rice is its ability to naturally regulate cholesterol levels. Monacolin K, present in this yeast, inhibits a key enzyme in the liver's production of cholesterol (HMG-CoA reductase), leading to a reduction in LDL ("bad") cholesterol and an increase in HDL ("good") cholesterol.
By regulating cholesterol, it helps prevent plaque deposits in the arteries, thereby reducing the risk of cardiovascular disease, hypertension and stroke. It is often used as a natural alternative to chemical statins, particularly for people wishing to avoid their side effects.
Red yeast rice is also beneficial for lipid metabolism and weight regulation. By reducing the accumulation of fats in the blood, it promotes better blood circulation and reduces the risk of metabolic disorders such as metabolic syndrome and type 2 diabetes.
Thanks to its high antioxidant content, it protects cells against oxidative damage, responsible for premature aging and chronic inflammation. It is therefore invaluable for maintaining healthy blood vessels and limiting the effects of oxidative stress on the heart.
Finally, some studies suggest that red yeast rice may play a role in regulating blood pressure and improving endothelial function, further enhancing its value for cardiovascular health.
How should red yeast rice be consumed on a daily basis?
Red yeast rice is generally taken as a dietary supplement in capsule or tablet form, to ensure optimal monacolin intake.

Does red yeast rice have any side effects or contraindications?
Although natural, red yeast rice acts in a similar way to statins and may therefore cause side effects in some people. Among the most frequently reported effects are :
Muscle pain and cramps (myalgia), linked to reduced production of coenzyme Q10.
Digestive disorders, such as bloating or nausea, which are generally mild.
Unusual fatigue, due to its impact on energy metabolism.
It is not recommended for people suffering from liver or kidney disease, or those taking statins or anticoagulants, due to the risk of drug interactions.
Pregnant and breast-feeding women should also avoid its consumption, as its effect on foetal development has not been sufficiently studied.
Lastly, prolonged consumption at high doses can lead to liver toxicity, hence the importance of respecting recommended dosages and medical follow-up in the event of prolonged intake.
How to choose quality red yeast rice?
To guarantee the efficacy and safety of red yeast rice, it's essential to choose a high-quality product that meets European safety standards. Here are a few criteria to check:
A controlled monacolin K content, not exceeding 10 mg per day, in line with EFSA (European Food Safety Authority) recommendations.
A certified citrinin-free product, a natural toxin produced by certain molds that can be toxic to the kidneys and liver.
A traced and controlled origin, with regular analyses guaranteeing the absence of contaminants.
A combination with coenzyme Q10, to compensate for the natural decline in this molecule induced by red yeast rice.
Red yeast rice is available in pharmacies, organic stores and specialized stores, in capsule or tablet form, or in combination with other protective nutrients.
