Red yeast rice or Monascus purpureus is a type of fungus that grows on rice and ferments it, turning it into a reddish colour. Since the Ming Dynasty, it has been included in Chinese pharmacopoeia and it has been associated with properties for relieving digestive or circulatory issues.
The beneficial effect of red yeast rice is related to substances generated during the fermentation process: monacolins, and in particular, monacolin K. These substances help to limit the synthesis of the red yeast's fatty acid and endogenous cholesterol in the body. Red yeast rice also contains other compounds such as isoflavones and sterols which boost its beneficial antioxidant effect.
Before taking a red yeast rice supplement, you will need a comprehensive cardiovascular risk assessment from your doctor. Lifestyle habits are the first thing to look out for when cholesterol levels are high such as eating a balanced diet and being physically active. Remember that supplements with red yeast rice are not indicated if you are already being treated for hypercholesterolaemia with medication.
It should not be taken with other dietary supplements that contain the same ingredient. Do not take more than 3 mg of monacolins per day and follow the instructions indicated on the label. This supplement is not indicated for use in children, during pregnancy/breastfeeding, or by those over 70 years. If you have any questions or experience any undesirable effects, please consult a healthcare professional.
