supplements - Red yeast rice

What is it

Red yeast rice is a substance produced when cooked rice has been fermented using  red yeast. This procedure has been practised in China since as far back as 800 A.D and is used to produce a food preservative and a flavouring or is dried to make a medicine.

Red yeast rice contains in addition to the usual nutrients found in rice, a mixture of compounds, which help lower cholesterol levels. These compounds are thought to be sterols, fatty acids and monacolin K. Monacolin K has been shown to inhibit the production of liver enzymes that manufacture cholesterol and is similar in action to many drugs normally used to treat high cholesterol levels.

Supplementation

• Traditionally Red yeast rice has been used in Chinese herbal medicine for digestive and circulatory disorders.
• Modern research has confirmed that Red yeast rice may be useful at lowering cholesterol, however the quality and potency of some supplements has been questioned. Supplements need to be guaranteed free from the toxin, citrinin and be standardised so that they contain around 0.5% monacolins.
• It is suggested that if you are using Red yeast rice as a supplement, you be may depleting co-enzyme Q10 from the body, it may therefore be beneficial to take a coQ10 supplement to offset this loss.
