The emerging TPN requires water (30 to 40 mL/kg/day), energy (30 to 35 kcal/kg/day, depending on energy expenditure; up to 45 kcal/kg/day for critically ill patients), amino acids (1.0 to 2.0 g/kg/day, depending on the degree of catabolism), essential fatty acids, vitamins, and minerals (see table Basic Adult Daily Requirements for .

The precipitation of calcium phosphate is not easily predictable when the concentrations of these two salts are high and this situation constitute one of the major danger that can destabilise the parenteral nutrition admixture. The precipitation kinetics of calcium phosphates, namely, hydroxyapatite (HAP), dicalcium phosphate dihydrate (DCPD), dicalcium phosphate anhydrous (DCPA), and monocalcium phosphate monohydrate (MCPM), were studied at 30C by mixing calcium hydroxide, water, and phosphoric acid.
