The study included 161 postmenopausal women, average age 59 years, who all had low bone mass placing them at risk for fracture. One group was randomly assigned to take daily potassium citrate supplement as tablets, which provides a very small amount of base -- alkali. The other group took a potassium chloride supplement, which provided the same amount of potassium but without base.
The study, published in the November Journal of the American Society of Nephrology, finds women taking the base supplement had a significant, 1 percent increase in bone mineral density in the vertebrae of the lower back. For women taking the non-base potassium chloride supplement, lumbar spine bone mineral density decreased significantly by approximately 1 percent.
"Our results demonstrate for the first time that merely by partially reversing the acidity of the diet, bone mass increased rapidly and in amounts that are within the range of increases produced by common Food and Drug Administration approved medicines," said Dr. Reto Krapf, of the University of Basel, in Switzerland
