Potassium Content in the
Potassium Content in the Body:
The total body potassium content is dependent on sex, age, and, most
importantly, muscle mass (which contains 60-75% of total body
potassium), and is approximately 40-45, and 50-55 mmol per kilogram
of body weight for normal adult women and men, respectively. These
values decrease with age and are 20% less in the elderly because of
a decrease in muscle mass.
