Minerals Tablets
» Minerals Tablets contain two or more minerals derived from substances generally recognized as safe, furnishing two or more of the following elements in ionizable form: calcium, chromium, copper, fluorine, iodine, iron, magnesium, manganese, molybdenum, phosphorus, potassium, selenium, and zinc. Tablets contain not less than 90.0 percent and not more than 125.0 percent of the labeled amounts of calcium (Ca), copper (Cu), iron (Fe), magnesium (Mg), manganese (Mn), phosphorus (P), potassium (K), and zinc (Zn), and not less than 90.0 percent and not more than 160.0 percent of the labeled amounts of chromium (Cr), fluorine (F), iodine (I), molybdenum (Mo), and selenium (Se). They contain no vitamins. They may contain other labeled added substances in amounts that are unobjectionable.
Packaging and storage
Preserve in tight, light-resistant containers.
Labeling
The label states that the product is Minerals Tablets. The label also states the salt form of the mineral used as the source of each element. Where more than one Assay method is given for a particular mineral, the labeling states the Assay method used only if Method 1 is not used.

note
In the following Assays, where more than one Assay method is given for an individual ingredient, the requirements may be met by following any one of the specified methods, the method used being stated in the labeling only if Method 1 is not used. Commercially available atomic absorption standard solutions for the minerals, where applicable, may be used where preparation of a standard stock solution is described in the following Assays. Use deionized water where water is specified. Where atomic absorption spectrophotometry is specified in the Assay, the concentrations of the Standard preparations and the Assay preparation may be modified to fit the linear or working range of the instrument.
