According to a new study, certain nutritional supplements may not do much for maintaining heart health.

一项新研究指出,某些营养补充品对于维持心脏健康用处不大。


Researchers focused on vitamin and mineral supplements like vitamin C and calcium, but found no no benefits in preventing cardiovascular disease or early death.

研究人员对维生素 C 和钙等维生素和矿物质补充品进行专注研究,但并未发现它们对预防心血管疾病或早逝有任何益处。
