N-acetyl l-tyrosine is a soluble form of the amino acid l-tyrosine. It converts into L-DOPA, which in turn becomes noradrenaline and dopamine. These catecholamines play a role in forming memories, boosting mood, and overall cognitive function. N-acetyl l-tyrosine is used by many individuals as a part of a pre-workout stack because tyrosine supplements can combat mental exertion, leading to a better and more focused workout.
L-Tyrosine is a nonessential amino acid, which means that the body alone can manufacture large enough amounts that it need not be supplemented through dietary means. However, a deficiency may be cause for supplementation. It is recommended that users should take servings of 400mg (about 1/8 tsp) per day, preferably directly prior to a meal.
