This study was carried out in 2012- 2013 to estimate calcium requirements in children age 3-5, using the calcium balance method. A total of 30 children participated in study. Each participant was subjected to a low calcium intake (300 mg/day) for 15 days. After an interval of 2 weeks, another 15 day period was set with a high calcium intake (600 mg/day) for each subject. Calcium intake levels were calculated based on the Vietnamese Food Composition Table published in 2007. Calcium content in intake, feces and urine were analyzed by Atomic Absorption Spectrophotometer. Calcium balance was calculated for each dose of calcium intake. The Calcium requirement was estimated by linear regression between calcium intake and calcium balance. The results showed that the calcium requirement at 140 mg/day of Calcium retention was 378 mg/day in the study children aged 3-5 years.
