摘要
近10多年来,液相色谱-质谱法(LC-MS)已能精确区分且定量测定血清25-羟基维生素D2(25(OH)D2)和25-羟基维生素D3(25(OH)D3)水平,由此发现维生素D3的营养能力优于维生素D2。本文介绍用25-羟基维生素D水平评估维生素D营养状况的理由及定量测定25(OH)D2和25(OH)D3方法的演变过程,综述比较维生素D2和维生素D3提高血清25(OH)D2和25(OH)D3水平能力的临床数据,并得到如下结论:为了预防和治疗维生素D不足或缺乏,临床医师应该首选维生素D3补充剂。
LC-MS has been able to accurately distinguish and quantify serum levels of 25(OH)D2 and 25(OH)D3 over the last decade.It is found that the nutritional effects of vitamin D3 are better than those of vitamin D2.This article describes the reasons for using 25(OH)D as assessment for nutritional status of vitamin D and an evolution of quantitative determination of 25(OH)D2 and 25(OH)D3 levels,and reviews clinical research data on improvement of 25(OH)D2 and 25(OH)D3 levels in serum by supplementation of vitamin D2 and vitamin D3.Therefore,clinicians should prefer vitamin D3 supplements in order to prevent and treat vitamin D insufficiency and deficiency.
