127-40-2 - 简介

叶黄素是一种天然存在于植物和动物中的黄色色素，属于类胡萝卜素的一种。

叶黄素具有很强的抗氧化性质，能够中和自由基，保护细胞免受氧化损伤，从而对增强免疫力、抗衰老和预防癌症等方面具有积极的作用。
在保健品中，叶黄素被广泛应用于调节眼睛健康，保护视力和预防眼部疾病。

叶黄素的制法主要有两种，一种是从天然植物中提取，如藻类、菠菜和玉米等；另一种是通过人工合成方法制得。其中，人工合成的叶黄素也广泛应用于工业生产中。

叶黄素的安全信息：一般来说，叶黄素是一种相对安全的物质。食用适量的叶黄素通常不会产生明显的副作用。个别人群可能对叶黄素过敏，或者在过量摄入的情况下可能出现一些不适症状，如恶心、呕吐等。在使用叶黄素时应注意适量和合理用药。另外，对于孕妇、哺乳期妇女和儿童等特殊人群，应遵医嘱或谨慎使用。最后更新：2024-04-09 21:54:55
