L-TYROSINE

L-Tyrosine: One of the 20 amino acids used by cells to synthesize proteins, L-Tyrosine is a starting material for neurotransmitters and has been shown to increase plasma neurotransmitter levels. Studies have found this amino acid to be beneficial for stress, cold, fatigue, prolonged work and sleep deprivation, reductions in stress-induced weight loss and improvements in cognitive and physical performance.
