Calcium does not build bone, but if you don't take enough for your system, your body will leach the calcium out of your bones. If you take to much, you can get stones. You can go get a blood test for calcium, magnesium, and D3. This 3 are critical for us that have bone loss.

It is best is you eat all the right foods that give us the nutrients we need, but most of us don't eat that way. Supplements are the next best thing. Those of us with osteoporosis need a minimum of 1800 mg of calcium daily, split up into different times of the day, not all at once, and always take your vitamins with food. Many women take too much vitamin D3, and too much is not good for you. The best way to find out what and how much you need, is to get a blood test for calcium, D3, and magnesium. Then you have a starting point to go from. After my first set of blood tests for these 3; my doctor told me to take 4000 IU of D3 daily, 400 mg of magnesium daily, and 1800mg of calcium daily. 6 months later I had the tests done again, and my 3 levels were good (in the normal range)

I hope this helps someone :)

Only your doctor can decide how much D you need. They have to take a blood test for that. 1600 is usually what doctors recommend for calcium. But for either talking to your doctor is the best.

Same here. Taking Caltrate with D3.
My doctor also checked my D level and added additional D3 1000 IU to take each day.

I was told to make sure I took calcium citrate. Its easier for your body to absorb then regular calcium pills are.
