L-Tyrosine CAS:60-18-4 Introduction:
H&Z® L-Tyrosine is a precursor to neurotransmitters and increasesplasma neurotransmitter levels (particularly dopamine and norepinephrine)but has little if any effect on mood.The effect on mood is more noticeable in humans subjected to stressful conditions.
L-Tyrosine, it is an essential amino acid, which is a kind of important nutrition for human and animal metabolism, growth and development plays an important role, could be widely used in food, feed, pharmaceutical and chemical industry, etc.
