L-Tyrosine is an amino acid that is used to produce noradrenaline and dopamine; supplemental appears to be anti-stress for acute stressors (which tend to deplete noradrenaline) and may preserve stress-induced memory deficits.

Description

N-Acetyl-L-Tyrosine – NALT Dosage | 800 mg |

N-Acetyl-L-Tyrosine NALT dosage is a more soluble form of L-Tyrosine. L-Tyrosine is the precursor to two of the most important neurotransmitters in the human body – dopamine and norepinephrine. It enhances working memory and executive function through chemical signalers in the prefrontal cortex. In addition, because L-Tyrosine is necessary for the synthesis of thyroid hormone and epinephrine (adrenaline), L-Tyrosine supports healthy glandular function and stress response.* It is also said to increase focus ability and internalized motivation.

Tyrosine Pharmacodynamics

Tyrosine is a nonessential amino acid synthesized in the body from phenylalanine. Tyrosine is critical for the production of the body’s proteins, enzymes and muscle tissue. Tyrosine is a precursor to the neurotransmitters norepinephrine and dopamine. It can act as a mood elevator and an anti-depressant. It may improve memory and increase mental alertness. Tyrosine aids in the production of melanin and plays a critical role in the production of thyroxin (thyroid hormones). Tyrosine deficiencies are manifested by hypothyroidism, low blood pressure and low body temperature. Supplemental tyrosine has been used to reduce stress and combat narcolepsy and chronic fatigue.

Tyrosine Mechanism of Action

Tyrosine is produced in cells by hydroxylating the essential amino acid phenylalanine. This relationship is much like that between cysteine and methionine. Half of the phenylalanine required goes into the production of tyrosine; if the diet is rich in tyrosine itself, the requirements for phenylalanine are reduced by about 50%. The mechanism of L-tyrosine’s antidepressant activity can be accounted for by the precursor role of L-tyrosine in the synthesis of the neurotransmitters norepinephrine and dopamine. Elevated brain norepinephrine and dopamine levels are thought to be associated with antidepressant effects.

Tyrosine Uses

Tyrosine is a precursor to neurotransmitters and increases plasma neurotransmitter levels – mainly dopamine and norepinephrine. It has little effect on mood. The effect on mood is the most prominent on humans subjected to stressful conditions.

Many studies have found tyrosine to be useful during conditions of stress, cold, fatigue, prolonged work and sleep deprivation. With reductions in stress hormone levels, reductions in stress-induced weight loss seen in animal trials, improvements in cognitive and physical performance seen in human trials; however, because tyrosine hydroxylase is the rate-limiting enzyme, effects are less significant than those of L-DOPA.

NALT Dosage

Tyrosine does not seem to have any significant effect on mood, cognitive or physical performance in normal circumstances. A daily dosage for a clinical test supported in the literature is about 100 mg/kg for an adult, which amounts to about 6.8 grams at 150 lbs. The usual dosage amounts to 500–1500 mg per day (dose suggested by most manufacturers; usually an equivalent to 1–3 capsules of pure tyrosine). It is not recommended to exceed 12000 mg (12 g) per day.
