Beschreibung:

"The subcommittee that prepared the ninth edition of the RDAs created the category “Safe and Adequate Intakes” for nutrients with data bases insufficient for developing an RDA, but for which potentially toxic upper levels were known. In this category were three vitamins (vitamin K, biotin, and pantothenic acid), six trace elements (copper, chromium, fluoride, manganese, molybdenum, and selenium), and three electrolytes (sodium, potassium, and chloride).
