An adequate calcium intake is an essential part of the prevention and treatment of osteoporosis. Two to threeserves of calcium-rich foods each day provides sufficient calcium for most non-pregnant adults. If this target is not achievable, calcium supplementation is generally effective, cheap and safe for most people. Calciumcarbonate(without vitamin and mineral additives) is the preferred supplement in most cases. Problems with calcium absorption arise due to factors including high·fibre vegetarian diets, achlorhydria, long·term glucocorticoid therapy and vitamin D deficiency. Vitamin D deficiency is extremely common in some ethnic groups and the elderly who are housebound or in residential care. These at risk groups generally require vitamin D supplementation to achieve adequate intestinal absorption of calcium.
