is a nonessential amino acid synthesized in the body from phenylalanine.
It is an important nutritional ingredient and factor for biosynthesis
of the brain neurotransmitters epinephrine, norepinephrine, and dopamine.
Tyrosine is also used to produce one of the major hormones, thyroxin,
which plays an important role in controlling metabolic rate, skin health,
mental health, and growth rate.
Benefits of L-Tyrosine
- Tyrosine acts as an adaptogen, helping the body adapt to and cope
with the effects of physical or psychological stress by minimizing the
symptoms brought on by stress. This is primarily due to the fact that
tyrosine is a building block for norepinephine and epinephrine, the body's
two main stress-related hormones. Taken ahead of time, tyrosine allows
some people to avoid typical bodily reactions and feelings from stressful
situations like surgery, emotional upset, and sleep deprivation.
- L-Tyrosine is an amino acids that has been shown to help some people
suffering from depression. Depression has been associated with decreased
activity of the neurotransmitter norepinephrine. But norepinephrine synthesis
can be influenced by its amino acid precursor, tyrosine. Tyrosine (and
ultimately norepinephrine helps to promote positive moods as well as motivation
and drive. Depressed patients who were given tyrosine improved their sleeping
patterns, mood, libido, and other psychological and physiological patterns
within a week.
- This serious condition occurs in people who cannot metabolize the
amino acid phenylalanine, which leads to brain damage including mental
retardation. The treatment is dietary restriction of phenylalanine. Given
that tyrosine is made from phenylalanine, restriction of this latter amino
acid leads to deficiency of tyrosine.
