Calcium and Bone Health

  • Less than 10% of women in the United States have adequate calcium intakes (J Am Coll Nutr 1999;18:406S-412S).
  • Calcium supplements help protect the achievement and maintenance of bone mass at all life stages: childhood (J Clin Invest 1997;99:1287-94), adulthood (J Nutr 1995;125:2802-13), and old age (Am J Ther 1999;6:303-11).
  • The United States Food and Drug Administration has approved the following statement: "Regular exercise and a healthy diet with enough calcium helps teen and young adult white and Asian women maintain good bone health and may reduce their high risk of osteoporosis later in life. Adequate calcium intake is important, but daily intakes above about 2,000 mg are not likely to provide any additional benefit."
  • The beneficial effects of exercise for helping to maintain bone density is achieved only when total calcium intake exceeds 1000 mg/day (J Bone Miner Res 1996;11:1539-1544).
  • Optimal results from medical treatments for supporting adequate bone density requires a total calcium intake of 1200 mg/day (J Am Coll Nutr 2000;19:83S-99S).
  • Calcium supplements help bones maintain their integrity during minor traumas (Clin Ther 1999;21:1058-72; J Bone Miner Res 1996;11:1961-6).
