Can potassium citrate be used to treat osteoporosis?
—JANE MILLER, FNP, RD, CDE, Charlottesville, Va.

The use of potassium citrate for osteoporosis prevention and treatment is getting plenty of attention lately. Physiologically, the potassium citrate alkalinizes the system, which helps decrease urinary calcium losses, making more systemic calcium available for osteoblastic activity. The average increase in bone mineral density in one study was 1% over one year’s time (J Am Soc Nephrol. 2006;17:3213-3222).
