NCT ID NCT03440970

First seen Jun 26, 2026 · Last updated Jun 26, 2026

Summary

This early-phase study tested whether giving chloride supplements (lysine chloride) to people with stable heart failure could affect their body's fluid balance. Twenty participants took either the supplement or a placebo three times daily for five days. The goal was to understand how chloride affects blood volume and kidney function, not to treat symptoms directly.
