potassium chloride

Salt & electrolyte

Potassium chloride is the quiet electrolyte supplement — potassium where the recipe needs it, bitter enough that nobody adds more than necessary.

What it is

The potassium salt of chloride, supplementing an essential mineral that muscle and nerve function spend continuously. Human kitchens know it as salt substitute; pet recipes use it to hit potassium targets when the base ingredients fall short.

Why it's in pet food

Closing the gap between a recipe's natural potassium and the nutritional minimum — plant-heavy and grain-free recipes reach for it more. Its bitterness is self-limiting: no formulator includes a gram beyond need.

How Bowlmark scores it

Scores are deterministic math over the printed label — the rules below apply to every product identically, and nothing estimates or fills in a blank.

Neutral: no deduction, no flag, no bonus — a supplement doing supplement work. Potassium disorders (kidney disease's companions in both directions) are bloodwork-and-vet territory; the renal guide covers when potassium becomes a conversation, and no ingredient list participates in it.

For cats

Chronic kidney disease often depletes potassium in cats — a reason senior-cat diets mind their potassium, and a decision that belongs to bloodwork, not labels.
