Adequate lifelong calcium intake is essential in optimizing bone health. Recent National Health and Nutrition Examination Survey (NHANES) data were used to quantify variation in calcium intake across adult age groups, to relate these changes with energy intake, to assess differences in dietary calcium intake between supplemental calcium users and non‐users, and to evaluate associations between age and calcium density in the diet. This cross‐sectional analysis determined calcium and energy intake for 9,475 NHANES respondents during the 2003–06 period. Nutrient density was represented using calcium:energy ratios. When compared to the 19–30 y age group, median dietary calcium intake was lower in the 81+ age group by 23% in men (p<0.001) and by 14% in women (p=0.003). These reductions coincided with 35% and 28% decreases, respectively, in median energy intake (p<0.001). Although the frequency of calcium supplement use increased with age (p<0.001), among female supplement users, the decline in dietary calcium intake was greater than in non‐users (p=0.02). Calcium density in the diet increased relative to age in men and women (p<0.001); however, calcium:energy ratios were insufficient to meet target ratios inferred by adequate intake standards after age 50. Overall, although calcium supplementation and density were highest in older age groups, intakes remain insufficient in meeting recommended levels.
