L-Tyrosine is a free-form amino acid which rapidly crosses the blood-brain barrier. It is a precursor for the neurotransmitters dopamine, norepinephrine and epinephrine, for thyroid hormones, and for enkephalins, special peptides which subdue messages of physical discomfort.

Review
L-Tyrosine has proven to be a great way to relax and endure stressors of the work environment in short order. It is apparently a precursor to chemicals in the brain that make one feel good, and relieves a person of day-to-day pressures (at least psychologically). The Seacoast brand L Tyrosine is effective and runs at a great price. I recommend this product in conjunction with night-time 5HTP for even better results.

L-Phenylalanine, an essential amino acid, is a precursor of the amino acid tyrosine, and to a whole series of neurotransmitters and hormones. Phenylalanine is first converted to tyrosine, which becomes L-dopa, which converts to norepinephrine, a key neurotransmitter and an adrenal hormone. L-Phenylalanine is also a direct precursor of PEA (Phenylethylamine), another important neurotransmitter.
