什么良好饮食和生活习惯呢？另外，前一段时间大家讨论补钙、V D-3、V K-3时，我发现几个问题，

一是，Vitamin D-3 和 Vitamin K-2 是 fat-soluble vitamin，不能同时吃，所以可能不该买 Vitamin D-3 & K-2 在一起的，Vitamin D-3 & K-2 两者服用最好隔开3个小时；

二是，Vitamin K-2 是用 mk-7？还是 mk-4?，还是两者都同时服用？Vitamin K-2 mk-7 Dosage Recommendations 是 0.18 mg/day (180 µg/day)，这个应该是预防保健服用的剂量。而 Vitamin K-2 mk-4 Dosage Recommendations is 45 mg，可能是治疗大剂量，不是预防保健的剂量。Vitamin K-2 mk-4 成品有 100 mcg的，这个是预防保健服用的剂量？

三是，在Amazon上看到负面评论：

Vitamin K-2 mk-7

"Worst tachycardia ever!!!
i developed rapid heart beat after taking my first pill. I could tell within a couple of hours I was very anxious and high anxiety. When I went to bed I could not sleep and I never have that problem. I woke around 3a.m. with tachycardia. My pulse was 135. We headed to ER. This continued thru the night. Finally, the next day it went away after 12 hours or so. The. I was drained. Please take precaution with this supplement. I am fine now."

Vitamin K-2 mk-4

"Read up on side effects-not returnable and dangerous to some
Wish I could return this. After taking one dose, ended up in ER with low blood pressure and fast heart rate. I was scared to death that I had done permanent damage to my heart. Luckily I did not and after 12 hours everything resolved. Please look up the possible side effects before taking K2. Mine is considered rare, but I’ve now read of others on Amazon suffering similar."

所以吃不准是不是该开始补钙、Vitamin D-3 、Vitamin K-2 ？

如果想开始，这是我能总结出来的：

Calcium + Vitamin D-3：

目前只能算是在做homework，及时记录从大家的讨论中了解的一些信息。到底该怎么做？还是有些模糊。
