Sodium and potassium content in sports supplements based on whey protein
Different brands of three sports supplement types containing whey protein were evaluated: 15 whey protein supplements, 4 hypercaloric supplements and 7 protein bars. A sample preparation procedure was studied employing microwave-assisted wet digestion in order to determine the sodium and potassium c...
