The amino acid L-tyrosine plays a crucial role in your brain. The dominant feature of L-tyrosine is its ability to initiate and propel the development of neurotransmitters and hormones that work to keep your mind sharp and your outlook positive. Consult your doctor before taking L-tyrosine supplements, as the effects of this chemical on the nervous system are different for everyone.
L-tyrosine has an antidepressant effect on the nervous system through producing norepinephrine, a mood-regulating neurotransmitter. The University of Maryland Medical Center, or UMMC, states that as a stress hormone, norepinephrine helps nerve cells to communicate and regulate your body’s overall reaction to stress, including anxiety levels. As anxiety is often an indication of a break in communication between neurotransmitters, norepinephrine is commonly prescribed to inhibit norepinephrine reapsorption into cells.
Constant fluctuations in hormones raise the probability of anxiety twice as high for women than men, according to the Women to Women website. The gradual drop in progesterone -- a predominantly female sex hormone -- from perimenopause onward, marks the genesis of general anxiety for many women. L-tyrosine supplements may be able to ease this transition by boosting the pituitary, adrenal and thyroid functions responsible for creating progesterone and regulating its release into the body, according to the UMMC.
If you’ve ever experienced a “feel good” sensation that left you relaxed and uplifted, you have caught a peek at the behind the scenes work of L-tyrosine at its best. L-tyrosine is a building block for the pleasure hormone dopamine, a commonly prescribed remedy in the treatment of depression and anxiety. One way dopamine eases anxiety, according to MayoClinic.com, is by decreasing nerve sensitivity to glutamate, a brain stimulator that can cause you to be overwhelmed and overexcited.
