回复 goodbest 的帖子
In 2011, The Endocrine Society issued clinical practice guidelines for vitamin D, stating that the desirable serum concentration of 25(OH)D is >75 nmol/L (>30 ng/ml) to maximize the effect of this vitamin on calcium, bone, and muscle metabolism [37]. It also reported that to consistently raise serum levels of 25(OH)D above 75 nmol/L (30 ng/ml), at least 1,500-2,000 IU/day of supplemental vitamin D might be required in adults, and at least 1,000 IU/day in children and adolescents.
这里新发现说,浓度在30以上才是对身体最好的呢。
还说了,要维持这个浓度,承认每天至少要补1500-2000;小孩或少年每天至少1000才够。
我记得,一些癌症病人被检测出血内低浓度时(譬如10左右),医生给他们开的量是每周几万单位,而且连补几个月呢。
