072 过敏、鼻炎、爆痘、容易累?快去查查是不是身体里缺了它

讲点武德

不知道你有没有出现过这种症状: 天气、季节、环境一变就复发的慢性咽炎、鼻炎、湿疹; 花粉、猫毛、灰尘、冷空气……稍微有点什么刺激就立刻开始过敏; 吃完饭不久就开始胀气、胃疼、肠易激、反酸烧心,做了肠镜胃镜又检查不出问题; 训练后肌肉增长慢、恢复慢,减重时肌肉和力量一起掉,大强度运动之后特别容易感冒发烧; 无缘无故的会觉得精力差,干什么都提不起劲,天天emo…… 这些问题最折磨人的地方,往往不是某一次特别严重,而是始终无法彻底摆脱。继续拖下去,它们可能从“偶尔难受”变成生活的一部分:吃饭要躲着吃,换季要提前备药,运动不敢加量,工作时注意力被疼痛和疲劳不断打断,晚上又因为身体不舒服睡不好。 其实很多一直解决不了的小毛病,可能都跟身体里一种物质——骨化二醇的水平有关 欢迎大家加入听友群,可以添加小助理微信,小助理会将您拉进听友群中 02:50 骨化二醇是什么?它是跟骨头有关吗? 13:05 身体里缺了它,都容易出现哪些方面的问题?有科学依据吗? 19:53 怎么查自己的骨化二醇水平?检测结果怎么看? 26:04 检查出来我的骨化二醇水平挺高的,是不是就可以高枕无忧了? 27:38 重点聊聊骨化二醇缺乏对运动表现的影响 36:55 20/30/40/50/60~70ng/ml,不同的骨化二醇水平,都会对身体产生哪些影响?是补的越高越好吗? 61:52 为什么有人怎么都补不起来?骨化二醇怎么补最有效? 参考文献 1.
