Amino acid l-lysine tested for hormone effects in healthy volunteers
NCT ID NCT01220388
First seen Apr 19, 2026 · Last updated Jun 18, 2026 · Updated 8 times
Summary
This study looked at whether L-lysine, a common amino acid, changes levels of aldosterone and cortisol—hormones that control salt balance and stress. Twenty healthy men took L-lysine or a placebo for 13 days, then switched. Researchers measured hormone responses to standing, a drug, and a low-salt diet. The goal was to understand basic hormone control, not to treat any disease.
