Tyrosine is important to the structure of
proteins
and is the precursor of several neurotransmitters in the
body, including dopamine, norepinephrine, and
epinephrine. Tyrosine’s effect on neurotransmitters
makes it helpful for maintaining a positive mood.
L-Tyrosine is the first breakdown product of and similar
in many effects to L-phenylalanine, but less likely to
affect blood pressure. A precursor of dopamine,
norepinephrine, and thyroid hormone, it may help some
types of depression. In a double-blind study, as
little as 150mg has been shown to be an effective
stimulant for about 3 hours with no side effects.
Testing by the military showed it boosted performance.
Some take several grams a day. Helpful as a daytime
growth hormone releaser, especially with arginine,
glutamine, etc. before exercise.
Recommended dosage: One to two capsules per day
on an empty stomach.
Contents: 90 capsules, 500mg each.

lactating women, or by persons with the genetic metabolic
disorder of phenylketonuria (PKU), psychosis,
