What it is
N-Acetyl L-Tyrosine (NALT) is a water-soluble derivative of the amino acid L-tyrosine, a precursor to key neurotransmitters. It is formulated to enhance cognitive function and stress response.

How it works
NALT crosses the blood-brain barrier more readily than L-tyrosine, increasing the synthesis of dopamine, norepinephrine, and epinephrine. This supports focus, attention, and resilience under acute stress.
Who should take it
Adults looking to address brain fog, memory decline, attention difficulty. Particularly relevant for people who prefer a targeted single ingredient and who have ruled out an underlying condition that needs medical care first.
Avoid / careful
Pregnant or nursing women without clinician oversight. People on prescription medication affecting the same pathway should consult a doctor before combining. Side effects are uncommon at recommended doses but mild GI upset can occur when starting.

FAQs
Frequently asked
How is NALT different from L-Tyrosine?
NALT is acetylated, making it more soluble and potentially more bioavailable in the brain compared to standard L-Tyrosine.
When should I take NALT?
It is often recommended to take NALT in the morning or early afternoon on an empty stomach to optimize absorption and cognitive effects.
Can NALT help with mood?
By supporting dopamine and norepinephrine synthesis, NALT may indirectly contribute to mood regulation, particularly in situations of stress-induced depletion.

About N-Acetyl L-Tyrosine (NALT)
N-Acetyl L-Tyrosine (NALT) is a nootropic & choline supplement used to support brain fog and memory concerns. Soluble tyrosine for focus and stress resilience. It is available in capsule form and dosed for adults in India and internationally. As a western-tradition entry in the SacredBod catalog, it is positioned as a single-ingredient option that can be used on its own or layered into a broader protocol. N-Acetyl L-Tyrosine (NALT) works through the mechanisms characteristic of its class — see the mechanism and research sections for detail. It primarily acts on the brain, nervous system, and effects are dose-dependent, typically becoming measurable within 2-8 weeks for noticeable cognitive effects. Consistency matters more than dose size for this category.
Evidence
N-Acetyl L-Tyrosine (NALT) carries an evidence grade of B in the SacredBod catalog, reflecting good-but-limited human evidence for brain fog and memory concerns. Soluble tyrosine for focus and stress resilience. Benefits are cumulative rather than immediate, typically becoming noticeable within 2-8 weeks for noticeable cognitive effects, and individual response varies.
Dosing
A typical dose is 350 mg, taken with food, usually in the morning. Start at the lower end, assess tolerance, and stay consistent; more is not automatically better.
Cautions
Pregnant or nursing women without clinician oversight. People on prescription medication affecting the same pathway should consult a doctor before combining. Side effects are uncommon at recommended doses but mild GI upset can occur when starting.
