BioStacksHow Tyrosine supports brain
For brain support, Tyrosine is a supporting ingredient backed by research. L-Tyrosine is a non-essential amino acid and direct precursor to dopamine, norepinephrine, and epinephrine. Also a building block for thyroid hormones (T3/T4).
What dose to look for
Clinical studies typically use 500–2000 mg of tyrosine. Common supplemental range 500-2000 mg/day. Clinical stress protocols use 100-150 mg/kg body weight as a single acute dose. Supplements that fall short of this threshold are unlikely to match what clinical trials achieved.
Clinical research
Tyrosine has moderate clinical evidence for brain benefits. Multiple trials show it preserves cognitive function under acute stress like cold or sleep deprivation Learn more
