Description Usage Supplement Facts Douglas Labs® L-Tyrosine Capsules provide 500 mg of bioavailable L-tyrosine in each serving. Tyrosine is a precursor to several important chemicals like the neurotransmitters our nerves use to communicate. One of the neurotransmitters, dopamine, is responsible for facilitating aspects of thought, learning, and movement. L-Tyrosine can also potentially aid in the synthesis of epinephrine. This hormone/neurotransmitter is able to control heart rate and the diameter of blood vessels and air passages. Norepinephrine can also be facilitated by tyrosine and helps us with concentration and fight-or-flight responses.
