Dose and safetyThe dose that worked and the upper limit
The studies of calcium citrate taken by mouth that showed an improvement gave 600 mg a day.
The upper limit for adults is 2,500 mg of calcium a day, counted as the calcium itself, not the weight of the compound; above it, members see a note and are told they can take less.
