Potassium Calculator
The Potassium Calculator estimates your daily recommended potassium intake based on your age, gender, and activity level. This tool helps adults and athletes maintain electrolyte balance and improve heart health. Whether you are managing high blood pressure, training for a sport, or are pregnant, this tool provides personalized nutritional guidance to keep your body functioning optimally.
How Daily Recommended Potassium Intake Is Calculated
Your daily recommended potassium intake represents the amount of potassium your body needs to support vital functions like nerve signaling and muscle contractions. This calculation uses the NIH Adequate Intake standards as a foundation and adjusts them to fit your specific lifestyle.
Recommendation = Base Requirement × Activity Factor × Health Factor × Athlete Multiplier
Where:
- Base Requirement: NIH Adequate Intake based on age and gender.
- Activity Factor: Multiplier for exercise frequency (1.0 to 1.25).
- Health Factor: Adjustments for conditions like pregnancy or kidney disease.
- Athlete Multiplier: Additional 1.15x for intense training.
First, we establish a baseline requirement using NIH standards for your age and gender. Next, we apply multipliers for your activity level and health conditions to adjust for loss or increased demand.
Finally, we calculate the final daily goal that supports your unique physiological needs. This method provides a scientifically grounded estimate tailored to your body's specific demands.
What Your Daily Recommended Potassium Intake Means
This number represents your daily target for maintaining optimal heart rhythm, muscle function, and fluid balance. Meeting this goal helps prevent cramps, fatigue, and high blood pressure naturally.
Managing High Blood Pressure
If your goal is to lower blood pressure, aim for the higher end of your recommended range, typically between 3,400 and 4,700 mg. Increasing potassium intake helps your body flush out excess sodium and relaxes blood vessel walls.
Athletic Performance
For active individuals, this target accounts for electrolytes lost through sweat. Consuming enough potassium, often around 4,500 mg or more, helps prevent muscle cramps and speeds up recovery after intense workouts.
Kidney Health
If you have kidney disease, your calculated range will be much lower, often restricted to under 2,000 mg. Strictly adhering to this lower limit is crucial to prevent dangerous buildup of potassium in your blood.

To ensure you meet your needs, focus on whole foods like fruits and vegetables rather than supplements, and track your intake regularly.
