Summary

This study looks at whether taking potassium supplements can reduce the negative effects of a high-sodium diet on blood vessel function and blood pressure. Researchers will compare three different diet conditions in 30 healthy adults aged 18 to 45. The goal is to understand how potassium might help the body handle excess salt.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

Active substance
potassium chloride supplement
What this could lead to
If successful, this could show that increasing potassium intake helps counteract some of the harmful effects of a high-sodium diet on blood vessels and blood pressure.
What could go wrong
This is a small, early-stage study in healthy adults, not a treatment trial. Results may not apply to people with high blood pressure or other health conditions.

Dec 2026

An estimate. End dates often move.

Other sponsor

The registry's catch-all category, for sponsors it does not file as a company, a government agency, or a research network.
