I want to go to Hong Kong to buy some calcium tablets for my family, which is better to use ah?

I bought the Japanese Takeda's calcium think healthy chewable calcium tablets, last year bought several times, because before my mom went to square dance, always feel the legs and feet are not flexible, casually move two on the soreness. I bought her Takeda's Calcium Si Jian, eat quite a long period of time, it does have a role, and now my mom basically what difficult movements can handle, which should be eaten every day Calcium Si Jian calcium reasons are inseparable! I suggest that you can also buy this brand of calcium tablets for the family, and calcium Sijian is also very good to find, go to Mannings, Watson's, China Resources these brand chain stores can be found.
