N-Acetyl L-Tyrosine (NALT)
The Dopamine Precursor
N-Acetyl L-Tyrosine (NALT) is the amino acid behind motivation and mental drive. It's a more bioavailable form of L-tyrosine, the building block your brain uses to make dopamine and norepinephrine, the neurotransmitters behind focus, motivation, and alertness.
NALT is one of the most studied amino acids for sustaining cognitive performance under pressure. Where most nootropics support a baseline, NALT supports what happens when the day demands more than that.
How NALT Works
When your brain works hard, it spends dopamine and norepinephrine. NALT is studied for its role in supporting how the brain restocks them.
1.Precursor to dopamine and norepinephrine.
NALT delivers tyrosine, the amino acid your brain uses to produce dopamine (the neurotransmitter behind motivation and drive) and norepinephrine (the neurotransmitter behind alertness and focus).
2.More bioavailable than plain L-tyrosine.
The N-acetyl form is more soluble than standard L-tyrosine, which makes it easier for the body to absorb and use.
3.Supports cognition under cognitive demand.
Research suggests NALT is most useful when the brain is depleting catecholamines faster than usual, such as during long stretches of focus, stress, or fatigue.
4.Studied for working memory.
Multiple human RCTs have linked tyrosine supplementation to better performance on working memory tasks, especially in multitasking and high-demand conditions.

Why We Use It
NALT is the ingredient in DayShift designed for the third hour of the workday, when motivation thins and focus starts to drift. It supplies tyrosine, the raw material your brain needs to keep producing the neurotransmitters behind drive and attention.
800 mg per packet, dosed within the clinically studied range for cognitive performance under demand. We use the N-acetyl form specifically because it's more bioavailable than plain L-tyrosine.
