Tyrosine
Amino AcidsKey Benefits
How It Works
L-Tyrosine is the precursor to dopamine (motivation/reward), norepinephrine (alertness/focus), and epinephrine (fight/flight). It also produces thyroid hormones and melanin. Under stress or sleep deprivation, tyrosine stores deplete rapidly, making supplementation most effective in demanding situations.
Dosage & Timing
Recommended Dosage
500-2,000 mg daily
Best Time to Take
Morning on empty stomach, or 30-60 minutes before demanding tasks
Recommended Form
L-Tyrosine (free form, NOT NALT)
Side Effects
Generally safe. Rare headaches, GI discomfort. May worsen hyperthyroidism or anxiety in sensitive individuals.
Drug Interactions
May interact with MAOIs, thyroid medications, and levodopa. Avoid with melanoma.
What Does The Research Say?
Research shows significant cognitive benefits under stress, sleep deprivation, and cold exposure (military studies). Most effective when catecholamine-depleted. Less effective in rested, non-stressed individuals. N-Acetyl L-Tyrosine (NALT) has lower conversion.
