Potassium citrate

Potassium citrate has been studied in 3 papers since 2000: none in people yet, 3 in animals. The research so far is in animals. The newest paper, Feb 11, 2025: “Oral Citrate Supplementation Mitigates Age-Associated Pathologic Intervertebral Disc Calcification in LG/J Mice”.

What did studies of Potassium citrate find?

6

Studies of Potassium citrate measured 6 outcomes; the most studied are stem cell differentiation (1 study), grip strength (1) and intervertebral disc calcification (1).

Stem cell differentiation

  1. Potassium citrate decreases osteoclastic response in mice.

    “The treatment resulted in inhibition of the osteoclastic response and an early improvement in mechanical properties of the bone”

1 study

  1. Potassium citrate prevents decline in glomerular filtration rate in rats.

    “Intake of Na3 citrate/citric acid solution or K3 citrate solution, but not ammonium citrate/citric acid solution, prevented a decline in GFR in three-month-old rats with PKD.”
