L-Tyrosine is a non-essential amino acid that's precursor to dopamine, norepinephrine, and epinephrine. It is a popular supplement for increasing concentration and alertness. L-Tyrosine acts as a preventative amino acid that doesn't change the body, but prevents symptoms like reduced focus after long periods of exercise.
In addition L-Tyrosine has a synergistic effect with caffeine. L-Tyrosine causes catecholamine synthesis and caffeine increases catecholamine release. Catecholamines are responsible for preparing our body for physical activity, such as the fight-of-flight response
Our N-Acetyl L-Tyrosine is an enhanced form of L-Tyrosine that has great water solubility for increased absorption.
