Chemical analysis of commercially obtained potassium-containing salt substitutes was performed. The potassium content was remarkably uniform from sample to sample of each brand and even among different brands. When hypertensive outpatients ranked these products, several were shown to differ considerably in taste characteristics and in overall preference. A cost comparison showed salt substitutes to be less costly than prescription (pharmaceutical) potassium supplements.
