How N-Acetyl L-Tyrosine Works in the Brain

N-Acetyl L-Tyrosine is a highly bioavailable form of the amino acid L-Tyrosine, which serves as a precursor to the neurotransmitters dopamine and norepinephrine[1]. These neurotransmitters play crucial roles in cognitive function, mood regulation, and the body’s response to stress.

When you supplement with NALT, it is rapidly absorbed and converted into L-Tyrosine in the body. This increased availability of L-Tyrosine allows for enhanced synthesis of dopamine and norepinephrine, leading to the potential cognitive and mood-supportive effects associated with NALT.

It’s important to note that while NALT and L-Tyrosine both serve as precursors to these neurotransmitters, NALT is believed to have higher absorption and bioavailability due to its acetylated form[2]. This means that NALT may be more efficient at delivering L-Tyrosine to the brain compared to regular L-Tyrosine supplements.
