What is the correct daily dosage for calcium citrate with vitamin D?

Your doctor will tell you what an appropriate dose of calcium citrate with vitamin D is for you. Maximum daily dosage may differ depending on your age and condition. Your body's calcium needs range higher as you get older. For most adults, 1000 mg. of calcium per day from food and supplements suffices. Adults above 50 years of age require about 1200 mg. of calcium per day. Doctors do not recommend more than 2500 mg. a day for most adults.

In general, calcium absorption begins to decrease as the amount taken increases. The ideal amount to take at one time is up to 500mg of calcium. How much you need depends upon your diet. Calcium is relatively easy to get from the diet; however, many Americans still fail to do so. Generally, calcium supplements should contain 200iu of vitamin D and 250mg of magnesium for each 500mg dose of calcium to ensure optimal calcium metabolism and utilization. In addition to calcium citrate, calcium carbonate is also common. It is 42% calcium by weight, whereas calcium citrate is 21%. The carbonate form is best absorbed when taken with a meal and the citrate form is unaffected by timing. The dotFIT Super Calcium + uses the higher calcium content of carbonate and has the appropriate vitamin D and Mg as well. Below are calcium intake recommendations.  (http://ods.od.nih.gov/factsheets/calcium ).
