L-Tyrosin
L-Tyrosin Uses, Dosage, Side Effects, Food Interaction and all others data.
L-Tyrosin is a non-essential amino acid. In animals it is synthesized from phenylalanine. It is also the precursor of epinephrine, thyroid hormones, and melanin.
L-Tyrosin is a nonessential amino acid synthesized in the body from phenylalanine. L-Tyrosin is critical for the production of the body's proteins, enzymes and muscle tissue. L-Tyrosin 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. L-Tyrosin aids in the production of melanin and plays a critical role in the production of thyroxin (thyroid hormones). L-Tyrosin 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.

Uses
L-Tyrosin is an amino acid commonly found as a component in total parenteral nutrition.
L-Tyrosin is claimed to act as an effective antidepressant, however results are mixed. L-Tyrosin has also been claimed to reduce stress and combat narcolepsy and chronic fatigue, however these claims have been refuted by some studies.
L-Tyrosin is also used to associated treatment for these conditions: Chronic Renal Failure (CRF), Acute Renal Dysfunction, Amino acid supplementation
How L-Tyrosin works
L-Tyrosin 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.
Toxicity
L-L-Tyrosin has very low toxicity. There have been very few reports of toxicity. LD50 (oral, rat) > 5110 mg/kg.
Food Interaction
No interactions found.Elimination Route
L-tyrosine is absorbed from the small intestine by a sodium-dependent active transport process.
