红曲是天然他汀，更安全
真相
Monacolin K 化学等价于洛伐他汀，天然 ≠ 安全 + 无剂量控制 + citrinin 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。

红曲米是被一种红色霉菌发酵过的米, 而它真正的关键是: 里头有一种天然成分 (monacolin K), 和处方降胆固醇药洛伐他汀 (lovastatin) 是同一个分子。换句话说, 你买的天然版他汀, 装的就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).
