There are few researchs into changes in bone mineral density (BMD) associated with increased intake of Calcium (Ca) in young adults. In this study, Ca - rich milk was given to 5 male college students for 2 months. BMD in lumber spine and ultrasound parameters in calcaneus were measured before and after supplementation and 2 months after the end of supplementation. After the period of supplementation, BMD in lumber spine showed significant increase and remained high level in 2 months after the of supplementation. In contrast, ultrasound parameters showed no changes. These results indicate that Ca supplementation for young adults is useful in enhancing BMD.
