Amino Acid

L tyrosine

L-tyrosine is an amino acid formed from phenylalanine or obtained from dietary protein. It serves as a starting material for dopamine, noradrenaline and thyroid hormones.

It contributes to normal neurotransmitter-related pathways and complements focused performance formulations.

In everyday life, L-Tyrosine provides a building block used in neurotransmitter pathways that support focused thinking during demanding situations.

Its contribution depends on ingredient form, quantity and the complete formulation.

Ingredient overview

What it is

L-tyrosine is an amino acid formed from phenylalanine or obtained from dietary protein. It serves as a starting material for dopamine, noradrenaline and thyroid hormones.

  • Scientific identity: L-Tyrosine; classification: Conditionally essential, aromatic amino acid.
  • How it works: Made from phenylalanine or absorbed: It is conditionally essential - the body hydroxylates phenylalanine to make it when supply allows. Crosses into the brain: It competes with other large neutral amino acids for the same transporter at the blood-brain barrier.
  • Primary function: It contributes to normal neurotransmitter-related pathways and complements focused performance formulations.
  • What it supports: L-Tyrosine provides a building block used in neurotransmitter pathways that support focused thinking during demanding situations.
  • Important consideration: Its contribution depends on ingredient form, quantity and the complete formulation.

Formulation rationale

Why we use it

CARPEDIEM selected L-Tyrosine for a clearly defined role within a thoughtfully balanced formulation.

  • Formulation purpose: It contributes to normal neurotransmitter-related pathways and complements focused performance formulations.
  • Used in: CARPEDIEM MultiMen.
  • Works alongside: L-Tyrosine complements Iodine and Vitamin B6 to support a more coordinated functional-nutrition approach.
  • Meaningful contribution: L-Tyrosine provides a building block used in neurotransmitter pathways that support focused thinking during demanding situations. Supports neurotransmitter-related nutrition within balanced performance formulations.
  • Quality and scientific context: Its contribution depends on ingredient form, quantity and the complete formulation. 1 ingredient-specific study is included because the research reports a relevant benefit.
