How many glasses of milk a day in order for the body to get the right amount of calcium?

The recommended daily intake of calcium varies by age and gender, but for most adults, it's around 1,000 mg per day. One cup (about 8 ounces) of milk typically contains around 300 mg of calcium. Therefore, consuming about 2-3 cups of milk a day can help meet the daily calcium requirement, but it's also important to include other calcium-rich foods in your diet for optimal health.
