When to take Potassium
Pinned to with food, the best window for Potassium.
Why timing matters
Spread intake across the day rather than one large dose; rapid potassium rises stress the heart.
Morning vs. night
Either; many split across meals.
Why with food
Food reduces stomach irritation and slows absorption, lowering the spike in plasma potassium.
Recommended schedule
With meals
Small 99mg doses across 2–3 meals if used; food sources should remain primary.
Don't take with
- • ACE inhibitors, ARBs, potassium-sparing diuretics, NSAIDs (additive hyperkalemia risk)
FAQ
Why so little per pill?
US OTC potassium is limited to 99mg per dose because higher single doses can cause GI ulceration and cardiac risk.
Food vs supplement?
Food potassium is safer and more bioavailable. A medium potato or banana provides roughly what a supplement does.
Athletes and cramps?
Cramps are usually multifactorial; sodium and magnesium often matter more than potassium for endurance athletes.
