The Active Ingredient Is: N-Acetyl L-Tyrosine

N-Acetyl L-tyrosine is an amino acid derivative used to support neurotransmitter synthesis and brain function.

This form is an acetylated version of L-tyrosine, which is more soluble and bioavailable for absorption and utilisation.

What Does N-Acetyl L-Tyrosine Do?

N-Acetyl L-tyrosine helps support the production of dopamine, norepinephrine and epinephrine, which are involved in mood regulation, cognitive function and responses to stress. This aligns with research suggesting tyrosine can support cognitive performance under stress.

Dr. Deijen of Groningen University highlighted the role of tyrosine in maintaining cognitive function during stress, reflecting its place in normal brain function and neurotransmitter synthesis.
