L-Tyrosine for Focus & Concentration
Non-essential amino acid and precursor to dopamine and noradrenaline via the enzyme tyrosine hydroxylase; most consistent evidence is for preserving cognitive performance under acute stress, sleep loss, or cold exposure rather than baseline mood.
The connection
Difficulty concentrating, brain fog, and attention issues. Increasingly common in the age of distraction.
Also known as: L-Tyrosine, N-Acetyl-L-Tyrosine
