What it's actually good for
How it works
L-Tyrosine is a precursor to dopamine and norepinephrine, effectively preserving cognitive function during acute physical or environmental stress. It is less effective for general cognitive enhancement in non-stressed states.
Acts as a substrate for tyrosine hydroxylase to synthesize catecholamines, preventing their depletion during high-demand or stressful conditions.
Safety
- Avoid if taking MAOIs due to risk of hypertensive crisis.
- Consult a doctor if you have hyperthyroidism or Graves' disease.
- May compete with other amino acids for absorption.
