Curcumin, a turmeric extract, may protect against cardiovascular diseases by enhancing endothelial function. In this randomized controlled double-blind parallel prospective study, fifty-nine healthy adults were assigned to placebo, 50 mg (50 mg), or 200 mg (200 mg) curcumin, for 8 weeks. The higher curcumin (200 mg) supplementation produced a dose-mediated improvement in endothelial function measured by flow-mediated dilation (FMD). The outcome was a clinically substantial 3.0% increase (90% CI 0.7 to 5.3%, p = 0.032; benefit : harm odds ratio 546 : 1) with the 200 mg dose, relative to placebo. The 50 mg dose also increased FMD relative to placebo by 1.7% (-0.6 to 4.0%, p = 0.23; 25 : 1), but the outcome was not clinically decisive. In apparently healthy adults, 8 weeks of 200 mg oral curcumin supplementation resulted in a clinically meaningful improvement in endothelial function as measured by FMD. Oral curcumin supplementation may present a simple lifestyle strategy for decreasing the risk of cardiovascular diseases. This trial was registered at ISRCTN registry (ISRCTN90184217).
姜黄素是一种姜黄提取物,可能通过增强内皮功能来预防心血管疾病。在这项随机对照双盲平行前瞻性研究中,59名健康成年人被分配到安慰剂组、50毫克(50mg)姜黄素组或200毫克(200mg)姜黄素组,为期8周。较高剂量的姜黄素(200mg)补充剂通过血流介导的血管舒张(FMD)测量,在内皮功能方面产生了剂量介导的改善。相对于安慰剂,200mg剂量的结果在临床上有显著的3.0%的增加(90%CI 0.7至5.3%,p = 0.032;获益:伤害比值比546:1)。50mg剂量相对于安慰剂也使FMD增加了1.7%(-0.6至4.
