Roll Call does not check drug interactions or assess personal safety.
An alkaline salt made of potassium and bicarbonate ions, used both as a potassium source and as a buffering (acid-neutralizing) agent.
Why it’s used
Taken to supply potassium or to raise the body's acid-base balance slightly toward alkaline, sometimes included in bone-health or exercise-performance formulas.
What the evidence is for
correcting low potassium intake and supporting normal nerve and muscle function.
What the evidence says
NIH ODS describes potassium's established role in nerve signaling, muscle function, and blood pressure regulation, and supplementation reliably corrects low intake or deficiency. Evidence that potassium bicarbonate specifically improves bone density or exercise performance beyond correcting deficiency is more mixed and less settled. US regulators have historically limited over-the-counter potassium salt tablets to small per-dose amounts because of past reports of gastrointestinal injury from concentrated tablets, a manufacturing and formulation detail rather than a statement about the ingredient generally.
Context
Research on potassium bicarbonate as an alkalinizing agent has generally used doses expressed in millimoles per day rather than a standard mass unit, which limits direct gram-based comparison across studies.
