Thorne Potassium Citrate

One capsule of Thorne Potassium Citrate provides 99mg of potassium, just 2% of the daily value, which makes this a low-dose, titratable option rather than a single-serving fix for a large potassium gap. That's by design. Potassium in citrate form is well absorbed, and a modest per-capsule dose lets you dial in exactly how much you're adding on top of what you already get from food.

Thorne built this supplement around potassium citrate, providing essential mineral support for healthy heart, skeletal muscle, and urinary tract.

Supports the muscles that matter most – Potassium plays a direct role in heart and skeletal muscle contraction, nerve impulse transmission, and maintaining normal blood pressure.

Backs your kidneys and urinary tract – The citrate component alkalinizes urine, which supports kidney and lower urinary tract health and inhibits the growth of undesirable bacteria.

Dial in your own dose – At 99mg per capsule, you can take one to three daily and land wherever your actual dietary and training needs put you, rather than being locked into one fixed amount.

Potassium is the body's main intracellular mineral, meaning most of it lives inside your cells rather than in your bloodstream, and it's essential for muscle contractility, nerve signaling, and normal heart rhythm. Citrate's alkalizing effect on urine also creates a more favorable environment for certain botanical extracts, like berberine, that work best in alkaline urine, which is part of why this product is sometimes paired with Thorne's urinary tract support formulas.

How to Use Thorne Potassium Citrate

Dose: Take one capsule one to three times daily with food, or as recommended by your health professional.

Note: This is a daily potassium supplement built for titration over time, not a sweat-replacement product for during a long run or ride. If you need electrolytes mid-training or mid-race, reach for a dedicated hydration product formulated for that specific use.

If you take ACE inhibitors or potassium-sparing diuretics, talk to your doctor before adding potassium supplementation, since combining them can raise potassium to unsafe levels. Consult your healthcare provider before use if pregnant.
