L-Tyrosine

Precursor your brain uses for focus and drive

L-Tyrosine

What it is

L-Tyrosine is the direct precursor your brain uses to make its focus catecholamines, dopamine and norepinephrine. As a long fast draws those down, tyrosine helps replenish them, supporting sustained focus and cognitive flexibility when demand is high. It absorbs best on an empty stomach, so a fast is its ideal window.

L-Tyrosine helps support

  • Supports focus and mental drive*
  • Helps replenish catecholamines during a fast*
  • Supports cognitive flexibility under stress*

How it works

Tyrosine is the raw material for dopamine and norepinephrine synthesis. Supplying it during a fast, when catecholamine turnover is high, supports the neurotransmitter pools behind sustained attention.
