N-Acetyl L-Tyrosine
Also known as: NALT (acetylated L-tyrosine, note: lower bioavailability than free L-tyrosine)
Marketed as 'more soluble L-tyrosine,' though pharmacokinetic data show NALT delivers less tyrosine to plasma than free L-tyrosine on a gram-for-gram basis.
- Clinical dose
- Lower bioavailability than L-tyrosine, most efficacy data is from L-tyrosine itself
- Typical label dose
- 300 mg–1 g
- Category
- Nootropic
- Focus
- Mental Clarity
- Stress Resilience
What it is & how it works
NALT is acetylated to improve solubility, but the body must deacetylate it before it can serve as a catecholamine precursor. Free L-tyrosine has stronger published efficacy under stress.
Dosage
The clinically studied dose is Lower bioavailability than L-tyrosine, most efficacy data is from L-tyrosine itself.On labels you'll typically see 300 mg–1 g.
What the research shows
Used in formulas where formulators want the 'NAL' marketing, efficacy literature actually points to plain L-tyrosine being the better choice.
