Calcium

Calcium is a mineral that accounts for 1-2% of human body weight. It is the primary component of bones and teeth and also helps form and maintain bones. Besides its importance in bone health, calcium plays a role in a variety of other body processes including muscle and nerve function, glandular secretion and blood clotting.

Food & Beverage Sources

Milk, and milk products like cheese, yogurt, ice cream and foods made with milk, provides a majority of calcium in most American diets. However, leafy greens, broccoli, sardines, canned salmon, tofu and legumes are also notable calcium sources. Many foods and beverages such as juices, soy-based beverages and water are now calcium fortified, so check the label for calcium content.

Recommended Intake Levels

The daily calcium recommendation for children 4-8 years of age is 800 milligrams. Kids and teens ages 9-18 need 1,300 milligrams while men and women ages 19-50 need 1,000 milligrams of calcium daily. Adults over age 50 require 1,200 milligrams of calcium daily. Pregnant and lactating females ages 14-18 need 1,300 milligrams per day; those ages19 and above need 1,000 milligrams of calcium per day.
