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.
