What is NALT?

NALT stands for N-Acetyl-L-Tyrosine. It is an acetylated form of L-tyrosine, an amino acid involved in dopamine, noradrenaline, adrenaline, and thyroid hormone pathways.

How is NALT different from regular L-tyrosine?

NALT is a modified form of L-tyrosine. It is often chosen in practitioner formulas when targeted support for focus, mood, stress response, and neurotransmitter pathways is needed.

Can NALT support focus and mental performance?

Yes. NALT may help support working memory, focus, attention, and mental performance, especially during periods of increased cognitive demand or stress.

Can NALT support mood and motivation?

NALT supports dopamine, noradrenaline, and adrenaline pathways, which are involved in mood, motivation, alertness, and stress response.

Can NALT support thyroid hormone formation?

Yes. Tyrosine is involved in thyroid hormone formation. If you have thyroid disease or take thyroid medication, speak with your healthcare professional before using NALT.

How much NALT is in each serve?

Each serve provides 500 mg of N-Acetyl-L-Tyrosine. For this powder, one 1.25 mL scoop is approximately 500 mg, but always check the product label for exact scoop details.

How should adults take NALT Powder?

The common dosage range is 400 mg to 2 g daily. Start at the low end and increase only if required under practitioner guidance. Dividing the daily dose may be useful at higher intakes.

Can NALT cause side effects?

Higher doses may cause gastrointestinal discomfort or migraine symptoms in some people. If this occurs, reduce the dose or stop use and speak with your healthcare practitioner.

Are there any important cautions with NALT?

NALT is not recommended for individuals with hyperthyroidism and is contraindicated with MAO inhibitors. Use under practitioner supervision if you take medication, have thyroid concerns, mood concerns, blood pressure issues, or use other focus, thyroid, stress, or neurotransmitter support products.
