What research says

Studies in people

  • Open question

    Bone loss after menopause2

    In women past menopause, potassium citrate lowered one urine marker of bone breakdown, but other bone markers did not change.

  • Benefit

    Bone strength and calcium3

    In older adults, potassium citrate improved calcium balance and lowered a bone-loss marker, but longer trials are needed.

  • Benefit

    Blood pressure4

    In people, potassium citrate lowered blood pressure, with a bigger drop in those starting higher.

  • Benefit

    Bone density in older women5

    In women past menopause, potassium citrate increased bone density in the spine and hip over a year.

  • No harm found

    Bone strength after menopause6

    In women past menopause, taking potassium citrate for two years did not slow bone loss or build bone.

  • Benefit

    Bone breakdown7

    In young women, potassium citrate lowered a marker of bone breakdown and helped the body hold onto calcium.

The signal at the top counts the findings in people and in animal and lab studies. A concern in studies of people outranks animal and lab studies, and “No concerns” needs at least two findings in people. Findings whose study type is not stated are shown but not counted. This page is a reference, not medical advice. It describes what regulators and published research say. Talk to a doctor or dietitian about your own diet.
