Pure Encapsulations Potassium (citrate)

Potassium and sodium work as a pair to maintain the electrical charge across every muscle and nerve cell in your body, and that balance is what keeps your heart rhythm steady and your muscles contracting and releasing properly during a long effort. Most electrolyte products focus heavily on sodium and barely touch potassium, even though a balance of both are key for the whole system.

Pure Encapsulations Potassium (Citrate) provides 200mg of potassium per capsule to support nerve and muscle function, healthy water balance, and cardiovascular health.

Balances What Electrolyte Products Miss – Potassium works opposite sodium in maintaining cellular fluid balance and nerve signaling, so if your current electrolyte routine is sodium-forward, this fills in the side that's often underrepresented.

Supports Heart Rhythm – Beyond muscle contraction, potassium plays a direct role in maintaining a healthy heart rhythm, extending its relevance beyond the cramping conversation most electrolyte marketing focuses on.

A Moderate, Measured Dose – At 200mg per capsule, this is a moderate amount meant to supplement dietary intake, not replace it, which matters given how tightly potassium levels need to stay regulated in the body.

Potassium is the major cation of intracellular fluid and activates enzymatic reactions involved in nerve impulse transmission, muscle contraction, gastric secretion, renal function, and carbohydrate metabolism. Working alongside sodium, it helps maintain water balance, heart rhythm, and nerve and muscle function, and research suggests adequate intake may support healthy blood flow and cardiovascular health, as well as bone mineralization through its role in calcium absorption.

How to Use Pure Encapsulations Potassium (Citrate)

Dose: Take 1 capsule, 1 to 2 times daily, with meals.

This is a moderate 200mg dose meant to complement dietary potassium, not replace a full day's intake on its own.

Note: Not to be taken if you have hyperkalemia or abnormal kidney function, or take ACE inhibitors, angiotensin receptor blockers, or potassium-sparing diuretics. If you are pregnant or lactating, have any health condition, or are taking any medication, consult your health professional before use.
