atp production a pre exercise potassium cholecalciferol and creatine monohydrate combination optimizes extracellular potassium availability at the neuromuscular spindle to meet the increased demand during vigorous exercise at least 20 milliequivalents meq of potassium is generally recommended for athletes weighing up to 200 lbs an additional 10 meq should be added for 200 300 lb body weight hence 30 meq potassium supplementation at these levels raises no safety concerns in individuals that are healthy enough for sporting activity individuals with kidney failure and heart disease must be cleared by their health provider before using the nutritional supplements of the instant invention or engaging in vigorous sporting activity the instant nutritional supplements should not be used for any other purpose aside from pre exercise enhancement of muscle energy production and cramp prevention in fig3 is shown the chemical structure of potassium chloride potassium chloride is a metal halide salt composed of potassium and chloride it is odorless and has a white or colorless vitreous crystal appearance potassium chloride dissolves easily in water and has a salty taste when so dissolved potassium chloride is used in the treatment of hypokalemia low concentration of potassium in the blood and as an electrolyte replenishment referring now to fig4 therein is shown the chemical structure of potassium bicarbonate potassium bicarbonate is a colorless odorless slightly basic salty substance it occurs as a soft white granular powder and it is very rarely found in its natural form as a mineral called kalicinite this is used in some east african tribes.
