The evidence in words
How much to take
500–2,000 mg taken ~30–60 minutes before an acute stressor or demanding, sleep-deprived session. Not useful as a daily baseline.
Timing & separation
There are no strict timing conflicts on record for L-Tyrosine; consistency matters more than the exact hour for most goals.
Why the dose is what it is
Under acute stressors — cold, noise, sleep deprivation, cognitive load — catecholamine turnover spikes and tyrosine availability can become limiting. Supplementing may sustain synthesis and protect performance in exactly those conditions.
Bottom line
Situational, not daily. Take it before a cold, sleepless, or high-pressure cognitive challenge; skip it on ordinary days where it does nothing.
How it is used
As the entry records it, from the studies it summarises. Not a recommendation for you — doses that suit a trial population may not suit you.
