The Active Ingredient Is: L-Tyrosine

L-Tyrosine is an amino acid that serves as a building block for important neurotransmitters and for thyroid hormone synthesis. This product contains pharmaceutical-grade L-Tyrosine supplied in powder form for use as a single active ingredient.

This form is produced under GMP quality assurance with globally sourced ingredients, reflecting high standards for purity and potency. L-Tyrosine supports neurotransmitter production and thyroid function through its role as a precursor in thyroxine synthesis.

What Does L-Tyrosine Do?

L-Tyrosine is involved in the production of dopamine, adrenaline and noradrenaline, which are linked to mental alertness and stress response. It also participates in thyroid hormone synthesis, contributing to thyroid function as described in the provided research context. Dr. Deijen of University of Groningen found that tyrosine may support cognitive performance under acute stress.

In line with EFSA-informed understanding, this amino acid contributes to normal neurotransmitter function and supports normal brain function as part of a balanced diet.
