红曲是天然他汀，更安全
真相
红曲的莫纳可林 K 在化学上就是洛伐他汀；天然不等于安全：剂量没人管，还有桔青霉素毒素污染。
这话术为什么会流行
“天然”二字把一种药重新包装成保健品，绕开了人们对他汀的抵触，还能不用处方直接买。
机制速览
红曲米是被一种红色霉菌发酵过的米。它的关键在于：里头有一种天然成分叫莫纳可林 K（monacolin K），和处方降胆固醇药洛伐他汀（lovastatin）是同一个分子。所以货架上的天然版他汀，装的其实是一颗没标剂量的他汀。

European Journal of Preventive Cardiology, 24(13), 1431-1434. 28 brands analysed by UHPLC-DAD-QToF; monacolin K undetectable in 2, and across the remaining 26 it ranged 0.09-5.48 mg per 1200 mg of red yeast rice — 0.09 to 10.94 mg per day at the manufacturers' own recommended servings (a 120-fold spread).
