Product introduction:

Product Name: Red Yeast Rice (Contains 0.2%~5% Monacolin K)

Red yeast rice, which is a food raw material with a long history and rich benefits. Our red yeast rice is fermented through a strict technological process. Its special feature is that it contains 0.2% to 5% of Monacolin K, which is a compound with significant physiological activity.


Introduction to product source and production process

The process of making red yeast rice is a job that requires patience and skill. First, we select high-quality rice, and then ferment it with Monascus in a constant temperature and humidity-controlled environment. Over the next few days, we closely monitored the rice fermentation process to ensure that each grain of rice was evenly fermented by Monascus. Finally, the fermented rice is dried and packaged to become what we know as red yeast rice.

The main ingredient of the product: Monacolin K

Our Red Yeast Rice contains an active ingredient called Monacolin K, also popularly known as "Monacolin Acid". Scientific research has proved that Monacolin K can help maintain cardiovascular health and has a significant effect on preventing cardiovascular diseases such as heart disease.


The main effect of the product: beneficial to cardiovascular health

Among the many benefits of red yeast rice, its cardiovascular health benefits are the most prominent. Monacolin K can inhibit the synthesis of cholesterol in the body, thereby helping to reduce low-density lipoprotein cholesterol (LDL-C) in the blood, which is a substance known as "bad cholesterol". Therefore, eating red yeast rice in moderation can help maintain normal blood lipid levels, thereby protecting heart health.


Applicable people of the product: consumers who have a demand for cardiovascular health, consumers who have a preference for pure natural products, etc.

Whether you're looking for a food for cardiovascular health, or have a preference for an all-natural, no-additive product, our Red Yeast Rice is an excellent choice. It can be used as part of your daily diet to help you maintain a healthy lifestyle.


2. Our advantages】

Advantages of SGS-GMP certified factory:

Our red yeast rice is produced in a factory certified by SGS-GMP. This certification ensures that the production process of our products has reached international standards, and the environment is clean, the production process is standardized, and the product quality is controllable. We have a strict quality inspection process, from raw material procurement to production and processing, to the final product packaging, each step has a dedicated person to ensure the quality and safety of the product.


Produce

Our red yeast rice has been tested by δ13C in the laboratory of Istituto di San Michele All'Adige and certified to be 100% natural. This shows that our red yeast rice does not have any artificial ingredients, and all the benefits come from the pure natural fermentation process and the nutritional content of the rice itself. We firmly believe that only the most natural products can retain and exert their original benefits to the greatest extent.


Product Safety:

The content of citric acid in our red yeast rice products is extremely low, ≤5PPb, which is safer than many other products on the market. Citric acid is a common food additive, but excessive citric acid may have an impact on human health. We always put the health of consumers first, so we strictly control the content of citric acid in our products.


GMO Free:

In today's food market, more and more products contain genetically modified ingredients. However, the scientific community is still inconclusive about the impact of genetically modified foods on human health. For the safety of consumers, our red yeast rice products do not contain any genetically modified ingredients, which is also an important advantage of our products.


gluten free:

Our red yeast rice is an ideal choice for consumers who are gluten sensitive or who avoid gluten due to dietary habits. Our products are completely gluten-free, which means those with gluten sensitivities can eat them with confidence.

Low pollution of products:

Our red yeast rice products undergo strict quality control to ensure their low polycyclic aromatic hydrocarbons (PAHs) and benzo[a]pyrene (benzo[a]pyrene, BAP) content. PAHs and BAP are a class of chemical substances that are potentially harmful to human health and are commonly found in certain foods and environments. The PAHs content of our products is ≤50PPb, and the BAP content is ≤10PPb, which are far below the relevant standards. This means our red yeast rice products are safer without worrying about potential health risks.


Low Pesticide Residues:

We attach great importance to the safety of raw materials and strictly control the cultivation process of red yeast rice to minimize pesticide residues. We select high-quality rice as raw material, and follow good agricultural practices during the planting process, including rational use of pesticides, regular monitoring and control, etc. Our goal is to provide safe and healthy products to consumers, so that you can use them with confidence.


No plasticizers:

Plasticizers are a class of widely used chemicals commonly found in plastic products. However, long-term exposure to plasticizers may pose potential hazards to human health. In order to ensure the safety of the product, we strictly control the production process of red yeast rice and do not use any plasticizers. You can use our products with confidence and enjoy the all-natural, safe food benefits.


Through the above advantages, our red yeast rice products have won the recognition and trust of consumers. We continue to work hard and always insist on providing high-quality, safe and pure natural products to protect the health of you and your family.
