Title: Best quality
Review: Twinlabs makes the best quality amino acids I have found to date. L-Phenylalanine is converted by the brain into dopamine and norepinephrine, and by the adrenal glands into adrenaline. If you have a need for increased mental acuity or depression relief, this may be helpful. If you suffer from anxiety, this supplement is very likely to MAKE THINGS WORSE (see review below). People with cardiac arrhythmias may also want to avoid this. If you are on an antidepressant, especially an MAOI, avoid this until you've discussed it with your doctor.
