“At that time, their experts concluded: "Based on all the evidence, at a minimum, we recommend vitamin D levels of 30 ng/mL, and because of the vagaries of some of the assays, to guarantee sufficiency, we recommend between 40 and 60 ng/mL for both children and adults.”

14年开始医生让补充4000后，每年验一次，直到17年都正常，在40-60。然后这周四才验，正常最高应该80，我95了。 开始没多想，停VD就好了。 今天越想越不对，查了网站，觉得要躲洞里了，太阳也不能晒
主要近来有些症状和网上讲的类似，比如容易累，有一点尿频（每天比原来多一，两次），眼干，口干。
不知要多久这些症状才会消失？ 我懒得查血钙了，去年查的血钙还正常的，中间值偏低的地方。

注意文中那个表的时间线和正常值。
自2017夏起，我们这儿的正常范围改为20～60
