今天在COSTCO看到两种补钙的：

一种是“Calcium 600mg with 200 iu vitamin D supplement, From oyster shell”，卖$5.69

另一种是“Calcuim 600mg High potency Calcium, Naturally sourced from limestone”，卖$12.49

两种都标明“1500mg providing 600 elemental calcium”，数量也一样“500 tablets”，但为什么价钱却差这么多？哪种补钙效果好啊？

purity不一样?吸收效果不一样?

都不好

按吸收效果排给你参考:

#1: Coral Calcuim, 珊瑚钙,有点难找
#2: Milk Calcuim
#3: 吃 Cheses
#4: Citrate Calcuim

碳酸钙跟吃石头差不多(开玩笑,不过吸收效果是最差的)

楼主说的都是药片一样的硬钙片，对吧，这种老人吃了容易结石。

I think No 2 (High Potency) must be a calcium compound that can be more easily absorbed by the body that No. 1. A lot of these minerals come in different forms, some are easier to absorb and some are not. Can you check the ingredients and find out what calcium compounds No 1 and 2 contain?
