N-Acetyl L-Tyrosine vs L-Tyrosine

NALT is the more bioavailable form of L-Tyrosine, and breaks down into tyrosine in the kidneys. Tyrosine converts to L-DOPA in the brain.


N-acetyl L-tyrosine seems to contribute to a perceived reduction in stress.* As a cognitive supplement, L-tyrosine studies listed on Examine.com showed that it promotes working memory.*

NALT Interactions and Synergies

N-acetyl L-tyrosine can potentiate some stimulants and may interact with MAOIs.* Consult with a physician before taking NALT if you are on any medications.

When and How Much to Take

For sports performance stress reduction, NALT is best taken 30 to 60 minutes before exercise.

NALT Dosage

Take up to around 350mg, but start with 100mg to assess tolerance. Do not take more than 400mg daily as N-acetyl L-tyrosine has a long half-life.


N-acetyl L-tyrosine has a slightly sour, citrus-like taste. It’s somewhat similar to citrulline malate or ascorbic acid. It goes well with juice, or by itself in plain water or with sweetener. Despite it’s citrus taste, the dosage isn’t large enough to influence the overall taste of your workout shake.

Curator’s Experience

200-400mg of N-acetyl L-tyrosine has helped me start, and plow through, workouts when I wasn’t in the mood (leg days). I’ve found this is the primary benefit and it’s likely why it’s included in some pre workouts.

Anecdotally, there is a perceived reduction in stress* and workout intensity after taking NALT, compared to a workouts without NALT, but with the same weight. So you’re not likely going to lift more, but you may hate it less.

Should You Cycle NALT?

I’m including this in the ‘opinion’ section since I couldn’t find a solid source in cycling L-tyrosine or N-acetyl L-tyrosine. Because this ingredient is in C4 and other popular pre workouts, it’s safe to assume there are individuals taking this almost daily, depending on their weekly workout split. However, it’s best to cycle NALT to reduce your tolerance.
