What is the adequate intake of calcium?

Most people do not need to worry too much about calcium intake, since most have a calcium deficiency in the body. This is the main reason why many people need supplements of multivitamins and minerals that include calcium. As a general rule, the maximum amount of calcium that an ordinary adult can safely consume is 2500mg daily. In reality, there is no need for so much. For most adults, a 1000mg calcium intake is sufficient. Adults over 50 can increase calcium intake to 1200-1400mg per day to prevent bone damage caused by aging. The same applies for women who lose a significant amount of calcium with the menstrual cycle.

Calcium is especially important for infants and children. Babies should receive approximately 210 mg calcium / day, children over 7 months 270 mg calcium / day and older children, aged between 5 and 8 years, 500 mg calcium / day. Between 9 and 18 years, children should supply their bodies with a daily intake of about 1300 mg calcium as they are in the growth phase, when bones solidify and a new set of teeth appears.
