title: Optimum and tolerated intake of fluorine.
abstract: Optimum and tolerated intake of fluorine has been studied on the basis of body weight, caloric and fluid requirement of subjects belonging to different age groups. The main F-source is consuming drinking water, and this normally contains 1 mg F/l. Thus, that amount of F should be considered optimal which is ingested with drinking water containing 1 mg F/l. The optimum per kg of body weight is 0.045 mg in infants. It decreases with age, in adults it amounts to half the optimum for infants on a mg/l basis. The tolerated and the chronic tolerated toxic amounts have been estimated for the different age groups.
