Can You Take L-Tyrosine and N-Acetyl L-Tyrosine Together?

Use extra care with this pair

The short answer

N-Acetyl L-Tyrosine (NALT) is an acetylated form of L-Tyrosine that is converted to free tyrosine in the body. Taking both forms simultaneously provides an excessive dose of tyrosine, potentially leading to dopamine and norepinephrine overproduction.

How to arrange timing

Choose either L-Tyrosine or N-Acetyl L-Tyrosine, not both. L-Tyrosine generally has better conversion efficiency.

Important context

Whether supplements suit you together also depends on dose, product formulation, health conditions, and medication use. Ask a doctor or pharmacist first if you take medication, are pregnant or breastfeeding, or have a chronic condition.
