Tyrosine - Neural
L-Tyrosine is an
amino acid found naturally in our bodies. Tyrosine's main purpose is
to support the formation of neurotransmitters such as dopamine,
norepinephrine and epinephrine. Neurotransmitters are important
because they carry "messages" from one nerve cell to another
and play a vital role in our muscular function. Messages sent from the
brain to a muscle, for example, telling it to contract or relax are
sent via neurotransmitters. A loss in these neurotransmitters can lead
to physical and mental burnout and fatigue, as well as depression.
L-Tyrosine accounts for as much as 90% of the production of these
neurotransmitters, which are synthesized directly from this amino
Why should I use
Tyrosine? What are the benefits?
The stress of
everyday life can lead to burnout and depression. Scientists believe
that the main cause of this depression or mental fatigue is directly
related to decreased levels of dopamine, norepinephrine, and other
neurotransmitters in the brain. They believe that use of Tyrosine, in
addition to St. John's Wort, can enhance the half-life of these
compounds and naturally relieve everyday symptoms of mental and
physical burnout, which can lead to better workouts and increased
productivity on an everyday basis. L-Tyrosine is believed to upgrade
the production of neurotransmitters and thus stave off fatigue and
mental breakdown that can occur during a hectic schedule or after an
unusually difficult workout.
What research has
been done on Tyrosine?
There have been a
number of published studies showing the positive effects of taking
L-Tyrosine. These studies have demonstrated that consuming Tyrosine
enhances the production of neurotransmitters and may, in fact,
alleviate certain symptoms of depression and improve alertness and
focus. Also, studies performed by the military have shown that
consuming a L-Tyrosine supplement may enhance cognitive performance.
What doses of
Tyrosine should be taken?
There are no
definitive studies showing what doses of L-Tyrosine are most
effective. However, many scientists believe that taking 3gm of
Tyrosine before a workout can lead to increased strength and intensity
and more mental focus. Also, consuming 2-3gm of Tyrosine with a high
carbohydrate meal can help prevent the sluggish feeling caused by
increased levels of serotonin, which decreases alertness.
What side effects
are caused by Tyrosine?
L-Tyrosine has thus
far been shown to be extremely safe and effective. No known side
effects have been reported.
