The Active Ingredient Is: L-Tyrosine

L-Tyrosine is an amino acid that your body uses to support the production of catecholamines, including dopamine and norepinephrine. This single-ingredient supplement comes as free-form L-Tyrosine to support normal neurotransmitter function.

Form and source information show the ingredient is supplied as a pure amino acid, usually produced in GMP-certified facilities and described as free-form L-Tyrosine in standard supplement practice.

What Does L-Tyrosine Do?

L-Tyrosine acts as a natural building block for dopamine and norepinephrine, which are involved in motivation and stress response. Research suggests it may help cognitive performance under acute stress conditions.

Dr. Jongkees of Leiden University found that higher availability of tyrosine can help support working memory, mental flexibility, and focus during demanding tasks.

This information aligns with EFSA-style understanding of amino acid function in supporting neurotransmitter synthesis and cognitive processes under stress.
