Effect of habitual dietary calcium intake on calcium supplementation in 12-14-y-old girls

Background: There is no agreement on how much calcium young girls need for optimal bone mineralization. Objective: We evaluated whether the effect of calcium supplementation on whole-body bone mineral accretion depends on habitual calcium intake. Design: This was a randomized, double-blind, placebo-...

Zusammenfassung:	Background: There is no agreement on how much calcium young girls need for optimal bone mineralization. Objective: We evaluated whether the effect of calcium supplementation on whole-body bone mineral accretion depends on habitual calcium intake. Design: This was a randomized, double-blind, placebo-controlled, 1-y calcium intervention study of girls aged 12-14 y selected from a larger group according to habitual calcium intake: subgroup A (n = 60) habitually consumed 1000-1307 mg/d (40th-60th percentile), and subgroup B (n = 53) habitually consumed
