Delay of natural bone loss by higher intakes of specific minerals and vitamins

For early prevention or inhibition of postmenopausal and age-related bone l oss, nutritional interventions might be a first choice. For some vitamins a nd minerals an important role in bone metabolism is known or suggested. Cal cium and vitamin D support bone mineral density and are basic components in most preventive strategies. Magnesium is involved in a number of activitie s supporting bone strength, preservation, and remodeling. Fluorine and stro ntium have bone-forming effects. However, high amounts of both elements may reduce bone strength. Boron is especially effective in case of vitamin D, magnesium, and potassium deficiency. Vitamin K is essential for the activat ion of osteocalcin. Vitamin C is an important stimulus for osteoblast-deriv ed proteins. Increasing the recommended amounts (US RDA 1989), adequate int akes (US DRI 1997), or assumed normal intakes of mentioned food components may lead to a considerable reduction or even prevention of bone loss, espec ially in late postmenopausal women and the elderly.
