Minerals play an important role in the body as essential nutrients. However, it's not easy to meet DRIs because food sources of minerals are limited. Recently, consumption of bottled natural water is increasing because of water pollution and distrust in tap water in Korea. The present study was conducted to investigate mineral contents in bottled natural water and theirs intakes in Korean adults. We analyzed 8 minerals in 7 kinds of bottled natural water by ICP‐spectrometer and conducted survey on intake status of water and natural water of 400 Korean young adults. The mean contents of Ca, Mg, Fe, Zn, Cu, Mn, Se, and Mo in bottled natural water were 22.5±22.5 mg/L, 10.6±10.0 mg/L, 0.3±0.2 ug/L, 2.1±1.5 ug/L, 1.2±0.1 ug/L, 1.4±0.4 ug/L, 1.9±1.0 ug/L, 3.3±0.8 ug/L. The mean age, height, weight, and BMI were 22.8 years, 174.9 cm, 68.6 kg, 22.4 kg/m 2 for male (n=150) and 21.3 years, 162.0 cm, 51.1 kg, 19.5 kg/m 2 for female (n=250). The daily intakes of total water and natural water as water itself were 670.3 mL and 212.2 mL for male and 488.0 mL and 132.7 mL for female. The daily intakes of Ca, Mg, Fe, Zn, Cu, Mn, Se, and Mo through natural water were 4.8 mg, 2.2 mg, 0.06 ug, 0.4 ug, 1.2 ug, 0.3 ug, 0.4 ug, and 0.7 ug for male and 3.0 mg, 1.4 mg, 0.04 ug, 0.3 ug, 0.7 ug, 0.2 ug, 0.3 ug, and 0.4 ug for female. To sum up these results, the contents of Ca, Mg, and Se in bottled natural water were relatively high and the daily intakes of these minerals were 0.5~1.0 % DRIs.
