L-Tyrosine is an essential amino acid which supports brain function. It can be converted by neurons in the brain into the neurotransmitters dopamine and norepinephrine (noradrenaline), hormones which are depleted by stress, excessive work and certain drugs. By replenishing norepinephrine in the brain, mental energy levels are enhanced and a feeling of contentment often occurs. L-Tyrosine boosts certain neurotransmitters in the brain and has been used to support stress reduction and depression. L-Tyrosine is converted in the body into other key biologic compounds, including L-dopa, CoQ10, thyroid hormones and melanin.
N-Acetyl L-Tyrosine vs. L-Tyrosine
N-Acetyl L-Tyrosine is an acetylated derivative of the essential amino acid L-Tyrosine. Ordinary L-Tyrosine is less stable and insoluble in water, which may result in reduced bioavailability. N-acetyl-L-Tyrosine, which is converted in the body to L-Tyrosine, is 20 times as soluble in water as L-Tyrosine itself. For this reason, it serves as an efficient supplement for raising tyrosine levels in the body, since undissolved substances are not absorbed from the digestive tract. Acetylation enhances the solubility and stability making it a more rapidly absorbed and bioavailable form of the amino acid L-Tyrosine which is less prone to urinary excretion.
The amino acid L-Tyrosine is a precursor for several substances made in the body including:
Neurotransmitters such as dopamine and norepinephrine; Melanins, the pigments largely responsible for skin and hair color; Thyroid hormones, such as thyroxine
L-Tyrosine Side Effects
L-Tyrosine may help some people in their fight against depression, but dosages above 500 mg, in some people, may cause anxiety, restlessness and rapid heart rate. L Tyrosine can cause over stimulation, restlessness, anxiety, and insomnia. Heart palpitations or arrhythmias are potential side effects that occur from high doses of tyrosine. These can occur in sensitive individuals in as low a dose as 200 to 500 mg. Always start with a low dose, such as 200 mg or less, even if it means opening a tyrosine capsule and taking a portion of it.
Suggested Use: As a dietary supplement take 1 dose (350 mg) 1-2 times daily or as directed by your physician. For maximum benefit, take up to 700 mg per day. Depending on your reaction, effective dosing can be as low as 150 mg per day. Read all label warnings prior to use.
WARNING: NOT INTENDED FOR USE BY PERSONS UNDER THE AGE OF 18. KEEP OUT OF THE REACH OF CHILDREN. If you are pregnant or breast feeding, consult your health care professional before using this product. People with known medical conditions and/or taking drugs should consult with a licensed physician prior to taking. Do not take in conjunction with MAO inhibitor drugs. Not for use by persons with a history of malignant melanoma or if bipolar, pregnant, suspect pregnancy, or lactating. Tyrosine should not be taken by those with conditions associated with increased dopamine levels such as mania and schizophrenia. This supplement may increase sensitivity to the effects of CNS stimulants. Caution is advised when taking tyrosine along with stimulants and dosages should be lowered accordingly.
