Lemonade vs. kidney stones: a tiny trial tests a tart remedy
NCT ID NCT05389995
First seen Jun 25, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This study looks at whether drinking lemonade (Crystal Light) and taking potassium citrate can improve urine chemistry in people who have had kidney stones and have low citrate or acidic urine. Ten adults will try each combination for a week and collect their urine for 24 hours. The goal is to see if these simple interventions can raise citrate levels and lower stone risk.
What this could mean
Our plain-language read of the trial. This is informational only — not medical advice or a prediction.
Active substance
potassium citrate and lemonade beverage (Crystal Light)
What this could lead to
If it works, this could point toward a simple dietary drink to help prevent kidney stones in people with low citrate levels.
What could go wrong
This is a very small trial with only 10 participants, so results may not apply to everyone. It's also not testing whether stones actually form, just urine markers.
