It kind of funny alot of the bottles are packaged in 650 mg. It is true about the body absorbtion of 500 mg which is why with eating right you can split the amount you need with food over 3 meals if you check on the the Cleveland website it will break down what different foods will make up the amount of calcium required. If you are on pills they need to be taken hours apart.

I was pulled off my calcium because I had enough in my diet. Your doctor can direct you on what is right for you.

Hi Diane, dark leafy vegetables, broccoli, kale (yuk) mushrooms, egg yolks, blackstrap molasses, some cerals, roasted almonds, or juices containing calcium, cottage cheese some antacids contain calcium check out www.Cleveland clinc.org if you can't do this you will need to take the calcium pills but stay away unless your door agrees calcium pills with iron. Hang in there.Hugs

Agree with all of the above posts. This is a question for your doctor to answer after doing blood work. I think that keeping our "levels" level is an important part of managing our osteoporosis. Time for a phone call Sassygal.
