Q: How much calcium intake is necessary for an adult of 60 years? Is it okay to take calcium supplement?

A:Calcium needs change during one's lifetime. Older men need more calcium. This is because, as you age, your body becomes less efficient at absorbing calcium and other nutrients. Green leafy vegetables, fish and their bones, milk and other dairy products are rich in calcium. Depending upon how much calcium you get each day from food, you may need to take a calcium supplement. Do not start any supplements without your doctor's advice because too much of calcium may not be a good thing.
