What is Potassium?
Potassium probably doesn’t cross your mind when you think about your heart beating, or how your muscles need to fire to lift weights, but this essential mineral and electrolyte is required for muscle contractions, nerve signals, and heart rhythm.
Why Does Potassium Matter?
Potassium keeps your muscles, nerves, and heart working in sync, from blinking and breathing to maintaining a steady heartbeat.
Healthy potassium levels:
- Ensure a regular, steady heartbeat by regulating the heart’s electrical signals. Even mild potassium imbalances can affect cardiac electrical stability.
- Support nerve signaling and muscle contractions
- Maintain fluid balance inside and outside cells, which is essential for proper hydration and cellular function
- Maintain cellular health by moving nutrients into cells and waste products out
- Regulate blood pressure by helping the body eliminate excess sodium

How to Interpret Potassium?
(Ranges may vary slightly by lab)
Standard reference ranges represent the middle 95% of healthy individuals but don’t necessarily reflect levels associated with longevity. Optimal ranges are derived from clinical guidelines, peer-reviewed research, and real-world outcomes data, with an emphasis on levels associated with peak functioning and reduced disease risk.
Benefits of Optimizing Potassium
- Stable and healthy blood pressure
- Improved muscle recovery and fewer cramps
- Reduced water retention
- Consistent heart rhythm
- Lower risk of kidney stones and bone density loss1,2

Low Potassium Levels (Hypokalemia)
Low potassium impairs the ability of cells to reset their electrical charge after firing, increasing the risk of muscle weakness and abnormal heart rhythms.
Symptoms:
- Muscle weakness, cramps, or pain
- Fatigue
- Irregular heart rhythm, palpitations
- Constipation
- Tingling or numbness in the hands and feet
Causes:
- Diuretics (e.g., water pills)
- Prolonged vomiting, diarrhea, or laxative use
- Kidney conditions
- Excessive sweating
- Heavy alcohol use
- Hormonal imbalances (e.g., Cushing’s syndrome)
Healthspan Impacts:
- Increased risk of arrhythmias, heart disease, and sudden cardiac death
- High blood pressure
- Muscle paralysis (in severe, acute cases)
- Structural kidney damage
- Increased risk of developing type 2 diabetes
High Potassium Levels (Hyperkalemia)
High potassium levels most often reflect impaired potassium clearance by the kidneys. This can disrupt electrical signaling in the heart, muscles, and nerves.
Symptoms:
- Abdominal pain
- Diarrhea
- Nausea and vomiting
- Chest pain
- Heart palpitations
- Arrhythmia
- Muscle weakness or numbness in your limbs
Causes:
- Kidney disease
- High-potassium diet
- Certain medications (e.g., blood pressure medication)
- Severe injuries or burns
- Hormonal disorders (e.g., Addison’s disease)
Healthspan Impacts:
- High risk of arrhythmias, heart muscle damage, and cardiac arrest3
- Muscle weakness and temporary muscle paralysis (in severe, acute cases)
- Damage to kidneys4
- Risk of metabolic acidosis, which can impact bone health
How Hone Treats Out of Range Potassium
Your Hone physician will evaluate whether potassium levels are normal alongside related biomarkers like sodium and magnesium, kidney markers to determine if treatment is needed.
- Oral potassium chloride* – prescribed to replace lost potassium levels
- Diuretics* – to excrete excess potassium out of the body
- Potassium binders* – for chronic or long-term management of high potassium
*Your Hone Physician does not prescribe these treatments but will recommend further evaluation and help coordinate care with your primary care provider when medical treatment is indicated.
- Electrolytes, including potassium supplements
- Magnesium5
*Avoid potassium supplementation without medical guidance if kidney function is impaired
- Increase potassium-rich whole foods like avocado or spinach
- Reduce processed sodium intake
- Add electrolytes to water, especially post-exercise or after sweat loss
- Manage stress
