Nucleophilic Defense Against PM Toxicity

University of Louisville·interventional·Posted Oct 19, 2017·Updated Jan 6, 2026

In Brief

A clinical study evaluating L-carnosine and placebo for Air Pollution Toxicity. Completed, enrolled 299 participants across 1 site.

Detailed Summary

Carnosine is a naturally occurring peptide found in high levels in skeletal muscle and the brain and is also available commercially as a dietary supplement. Since carnosine has anti-oxidant properties and air pollution exposure induces a state of oxidative stress, the purpose of this study is to see if those taking carnosine as a dietary supplement are protected from air pollution-induced oxidative stress and adverse cardiovascular outcomes.
