Good purchase

Getting old and probably need the calcium. Doesn't upset my stomach.

Broke leg doctor said bone density bad on second bottle.

The best Calcium supplement I have found. I showed my doctor the bottle and she started taking it too.

Good price, fast shipping, dissolve easily.Dissolve easily, fast shipping, good price.

I just started taking this. The product says to take 3 a day. It does not say if that is one 3x a day OR 3 pills at once. I found that odd. So on the first day, I took 3 pills in one dose. Within a hour, I had diarrhea.I really wanted to give this product a try, especially with the mixed reviews. A day or two after the side effects stopped, I did 1 pill for one day. No problem.I skipped a day. Then took two at once. My stool went soft within the hour, but wasn't to the extent on the first time.My guidance (and I am not a doctor) only take 1 per day.I'll update later about pain relief and bone improvement. It's too early to tell.

I sprained my wrist working out. Due to my "age" my trainer and physical therapist both assumed it was broken, because a 20 something at our gym sustained the same fall and broke hers. X-rays revealed no break, no fracture, just a sprain. They were astonished. I was a little surprised and relieved myself. This is not the only supplement I take, but it is my calcium supplement. I also take Boron. I am a 60+ year old woman whose bones appear to respond much better than a 20 something. It must work?!
