Category - Tyrosine

Tyrosine is a nonessential amino acid and a a precursor to some hormones and neurotransmitters [epinephrine, norepinephrine, and dopamine]. Therefore, tyrosine has been suggested to be ergogenic. Many studies failed to show performance improvement with tyrosine supplementation. However, tyrosine seems to improve workout in very warm conditions as heat may become limiting to the dopamine synthesis.
