title: Dietary potassium deficiency in the elderly: a controlled trial.
abstract: A controlled cross-over trial of supplementary potassium was conducted in 46 elderly people whose dietary intake of potassium appeared to be no more than 45 mEq per day. Their grip strength and mental function were no better after two weeks' treatment with 48 mEq than when they received placebo tablets. It was concluded that the possible benefits of widespread potassium supplementation do not justify the risks which would be incurred.
