Potassium Citrate vs. Potassium Gluconate: What's the Difference?
Edited by Aimie Carlson || By Harlon Moss || Published on December 2, 2023
Potassium citrate is a citric acid salt, used in medicine and food; potassium gluconate, a gluconic acid salt, is used for potassium supplementation.
Key Differences
Potassium citrate, a compound formed from potassium and citric acid, is commonly used for treating kidney stones. Potassium gluconate, on the other hand, is derived from gluconic acid and is primarily used as a potassium supplement in cases of deficiency.
In terms of chemical structure, potassium citrate is comprised of potassium ions and citrate, a tricarboxylic acid. Potassium gluconate contains potassium ions and gluconate, a molecule derived from glucose.
Potassium citrate has an alkalizing effect on urine, which helps in reducing kidney stone formation. Potassium gluconate's role is primarily to maintain potassium levels in the body, without specific effects on urine pH.
The medical uses of potassium citrate extend to managing conditions like cystinuria and uric acid kidney stones, while potassium gluconate is used for preventing or treating low blood potassium levels.
Potassium citrate is often found in food as a preservative or pH stabilizing agent, whereas potassium gluconate is more common in dietary supplements for potassium enrichment.
