Red Yeast Rice Extract | 2.95mg Monacolin K | 365 Capsules | Vit4ever

Red Yeast Rice Extract by Vit4ever

In Asian cuisine, red yeast rice extract has been used for centuries, long before it was sold as a supplement. It is made from ordinary white rice that is fermented with the fungus Monascus purpureus. During this fermentation process, the rice turns deep red and develops a group of compounds called monacolins, of which monacoline K is the best known. Vit4ever processes this fermented extract into a capsule containing 2.95 mg of monacoline K, supplemented with grape seed powder and the amino acid L-leucine. One bottle contains 365 vegan capsules, providing a full year's supply.

Fermentation: from white rice to red yeast rice

The process begins with cooked white rice, which is inoculated with the yeast fungus Monascus purpureus. The fungus grows in the rice and converts a range of natural substances during this growth, including pigments that turn the rice red. This fermented rice has been used since ancient times in China, Japan, and other parts of Asia, both as a colouring and flavouring agent in dishes and in traditional cuisine. The final product of this centuries-old process is now known in the supplement industry as red yeast rice extract or red yeast rice, two names for the same fermented raw material. Vit4ever uses a standardised extract from this fermentation process, so that each capsule contains a fixed amount of the measured compounds. The fermentation process itself usually takes several weeks, during which temperature and humidity are carefully monitored to ensure a consistent final product. Only after these weeks of controlled growth is the rice dried and ground into the extract that goes into the capsule.

What monacoline K is as a compound and how the extract is standardised

Monacoline K is one of the compounds that naturally occur during the fermentation of rice with Monascus purpureus. It belongs to a larger family of monacolins that are produced during this process, and it is the best-known variant in that family. Each capsule of this product provides 2.95 mg of monacoline K. Since 2022, the European Union has set a maximum of less than 3 mg of monacolins per daily dose, meaning that no health claims may be used for this product. We therefore only state what the compound is and where it comes from, not what it is claimed to do in the body. Red yeast rice is a natural product, and the amount of monacoline K that is produced during fermentation can naturally vary from batch to batch, depending on the type of rice, the fungal strain, and the fermentation conditions. For this reason, the extract is standardised after fermentation, so that each capsule contains the same amount of 2.95 mg of monacoline K, regardless of which fermentation batch was used. In addition to monacoline K, the fermentation process can also produce small amounts of citrinin, a compound that can form during the growth of the fungus. Vit4ever therefore tests each batch separately to ensure that the amount of citrinin remains well below the legal limit, in addition to the regular testing of the amount of monacoline K itself.

Grape seed powder and L-leucine as supplements

In addition to the rice extract, each capsule contains 100 mg of grape seed powder and 40 mg of L-leucine. Grape seed powder is the finely ground residue from grape seeds, a byproduct that naturally contains compounds from the grape and is easy to process into a powder for encapsulation. It is obtained after pressing grapes for juice or wine, making it a repurposed byproduct rather than a separately grown ingredient. L-leucine is an amino acid, one of the building blocks of proteins, and is frequently added to plant extract formulations. Both ingredients are regularly combined with red yeast rice in supplement form, although the main component of this capsule remains the fermented rice extract itself.

Origin and composition of the capsule

The capsule shell is made from hydroxypropyl methylcellulose, a plant-based material, making the product suitable for a vegan lifestyle. No colourings, flavourings, or magnesium stearate have been added to the formulation. Vit4ever has each produced batch tested by an independent German laboratory to ensure that the composition matches what is stated on the label. At a dosage of one capsule per day, a bottle of 365 capsules lasts a full year, without the need to order a new supply halfway through. This also makes it easy to incorporate the dosage into a regular daily routine without having to reorder in between.

Red yeast rice extract remains, at its core, a fermented rice product with a long history in Asian cuisine. Vit4ever captures this fermentation process in a standardised extract, with a fixed amount of monacoline K per capsule, independent laboratory testing of each batch, and a limited, clearly defined list of ingredients.
