Key Facts

  • Potassium is an electrolyte mineral that regulates nerve signaling, muscle contraction, and heart rhythm
  • Supports cardiovascular function and energy production at the cellular level
  • Potassium citrate is a highly absorbable form that addresses inadequate dietary intake
  • Each capsule delivers 99 mg of potassium in a clean, convenient format

Ingredients

Potassium (as potassium citrate), hypromellose capsule, leucine, microcrystalline cellulose, silicon dioxide.

Why We Chose This

Most people don't get enough potassium from food alone, which can quietly affect how your nerves fire, muscles contract, and heart beats. Potassium citrate is the form your body absorbs most efficiently because the citrate component enhances bioavailability. This formulation delivers a meaningful dose in a single capsule without unnecessary fillers, making it practical for anyone looking to fill a common nutritional gap that matters for long-term cardiovascular and metabolic health.

Frequently Asked Questions About Potassium Citrate

What is the supporting research for the benefits of potassium citrate?
How do I take potassium citrate?

Take 1-2 capsules daily with food to support your body's potassium levels and cardiovascular function.

Pair each dose with a full glass of water and take within 30 minutes after eating for optimal absorption.

Can I take potassium citrate with other supplements or medications?

Certain combinations — like potassium citrate with water pills or anticholinergic drugs — should not be used together without medical supervision due to risk of dangerously high potassium levels.
