New Era single cell salt number 4 contains FERR. PHOS, Iron Phosphate. Contains triturated (finely ground) tiny particles of cell salt in easy to take, dissolve on the tongue ‘FastMelt’ tablets with the essential nutrient biotin. These are made using processes associated with New Era for almost 90 years. Fast Melt Tablets - Each bottle contains 240 small \"melt under the tongue\" tablets, for which New Era is famous. Their cell salt nutrients are therefore more rapidly absorbed into the blood stream than any ordinary tablet can be expected to achieve when chewed, swallowed or taken with a drink. Biotin - New Era\'s original Tissue Salts now also have a little extra Biotin added, an essential nutrient which contributes to the normal energy yielding metabolism, functioning of the nervous system, normal macronutrient metabolism and psychological function. It also contributes to the maintenance of normal hair, skin and to the maintenance of normal mucous membranes. These Health Claims are approved as per the EU Register on Nutrition and Health Claims.
