The Active Ingredient Is: L-Tyrosine
L-Tyrosine is an amino acid and a building block for neurotransmitters that support focus, motivation and stress response.
This form gives L-Tyrosine as the one active ingredient in capsule form, with other ingredients used as inactive capsule materials. It is designed for daily use as part of a balanced diet and lifestyle.
What Does L-Tyrosine Do?
L-Tyrosine helps production of dopamine and norepinephrine, supporting cognitive performance under stress and mood balance according to evidence from clinical research. Dr. Jongkees of Groningen University reported improvements in working memory and task performance under stress in controlled trials.
These functions align with L-Tyrosine's role in normal brain function and stress adaptation, supported by established nutrition and neuroscience literature.
