Red yeast rice (紅麴) reduces the blood level of low-density lipoproteins (LDL, 低密度脂蛋白), or so called the BAD cholesterol (膽固醇), and long-term supplementation decreases the incidence of cardiovascular disease (心血管疾病). The mechanism of red-yeast-reducing-LDL is due to the structure of active ingredients(活性成分), the Monacolin K, similar to the Statins hyperlipidemia medicine(高血脂藥), so they may have similar benefits and side effects.
