Sourcing pharmaceutical-grade potassium DCA is considerably harder than sourcing sodium DCA. The market is smaller, fewer manufacturers produce it, and quality control is even more variable.

The same fundamental quality requirements apply: HPLC assay ≥99.5%, MCA testing by ion chromatography, independent third-party COA, heavy metals panel, and confirmed potassium salt identity.

The identity confirmation point deserves special attention for KDCA. Some suppliers selling potassium DCA are actually repackaging sodium DCA — the compounds look identical as white powders. A proper COA with ICP-MS elemental analysis confirming potassium content, not sodium, is the only way to verify you have the correct salt.

KDCA is not sold by most major research chemical suppliers. When you do find it, treat every COA with extra scrutiny. Ask specifically: is this ion chromatography confirmed as the potassium salt? Is MCA separately tested? Was this COA issued by an independent laboratory?

AuraDCA applies the same independent Eurofins Vilnius testing standard to all products — including potassium DCA when available.
