What is N-Acetyl L-Tyrosine (NALT)?

N-Acetyl L-Tyrosine (NALT) or N-Acetyl Tyrosine is an acetylated derivative of the essential amino acid L-tyrosine and is a more rapidly absorbed and bio-available form of the amino acid L-Tyrosine that is less prone to urinary excretion. Ordinary tyrosine is less stable and is insoluble in water, which may result in reduced bioavailability. Acetylation enhances and improves the solubility and stability of certain amino acids.

L-Tyrosine, or simply Tyrosine, is one of the 20 non-essential amino acids that are used by cells to synthesize proteins. Tyrosine is an amino acid that has an important role in the structure of almost all the protein found in the human body. It is primarily used to enhance focus and alertness. Tyrosine, also called L Tyrosine, is not an essential amino acid since it can be made from phenylalanine which is another amino acid. Supplementation with both tyrosine and phenylalanine results to alertness and mental arousal.

Tyrosine is the precursor of the thyroid hormones threonine and thyroxine, and the adrenal and growth hormones epinephrine, dopamine and norepinephrine. The function of the amino acid tyrosine is closely related with neurotransmitters and hormones in the body and is essential for normal mental functions. It is also used to create melanin the dark pigmentation in the skin which helps shield our body from the harmful UV rays of the sun. As with other amino acids, many vitamins and minerals improve tyrosine's absorption into the body. Dietary sources of tyrosine are principally derived from animal and vegetable proteins, which includes soy products, chicken, turkey, fish, peanuts, almonds, avocados, bananas, milk, cheese, yogurt, cottage cheese, lima beans, pumpkin seeds, and sesame seeds.

Tyrosine deficiency may cause a variety of conditions, including muscle loss, weakness, low protein levels, mood disorders and liver damage. Low levels have been linked to hypothyroidism (low thyroid function) and depression. Manifestations of tyrosine deficiency can also be evident through symptoms such as low blood pressure, low body temperature (such as cold hands and feet), and restless leg syndrome. Most people suffering by PKU (phenylketonuria, the inability to metabolize phenylalanine) are deficient in tyrosine.

Tyrosine helps regulate mood and stimulates the nervous system. It can also boost the metabolism and treat conditions characterized by chronic fatigue. The body needs adequate supplies of tyrosine to make many important brain chemicals that help regulate appetite, pain sensitivity, and the body’s response to stress. It is also needed for proper functioning of the thyroid, pituitary, and adrenal glands, as low levels of tyrosine may lead to chronic fatigue and sluggish metabolism.

The body needs both tyrosine and the essential amino phenylalanine to make epinephrine, dopamine, and norepinephrine, three neurotransmitters that play an important role in the way you perceive and interact with your environment. Without adequate amounts of phenylalanine, the body can’t manufacture its own supply of tyrosine; without adequate amounts of tyrosine, the body cannot metabolize phenylalanine. A scarcity of either of these amino acids could make you more susceptible to a number of mental disorders, including anxiety, depression, low libido, and chronic fatigue. Tyrosine supplements, especially when combined with 5-HTP (5-hydroxy-tryptophan) supplements, have been utilized successfully to treat depression. Tyrosine supplementation has also been used for treatment of allergies, headaches, Parkinson’s disease, and drug withdrawal.

What is N-Acetyl L-Tyrosine (NALT) used for and who uses it?

N-Acetyl Tyrosine supports brain function by inducing and improving the synthesis of the neurotransmitters norepinephrine and dopamine. When taken as directed by your health practice professional, L-Tyrosine is a precursor for and is converted into key physiological compounds including epinephrine, L-Dopa, Co-Q10, melanin, and various thyroid hormones. Many health practice professionals recommend taking N-Acetyl L-Tyrosine with other nutritional supplements and vitamins including folic acid and a B vitamin complex that includes vitamin B-6 (pyridoxine) so as to aid in L-Tyrosine's physiological conversion processes.

L-tyrosine supplements have been used as a therapeutic supplement for those with phenylketonuria, depression, Parkinson's disease, and those who want to improve their memory. Tyrosine supplementation may be used in the treatment of Parkinson's disease, because tyrosine can make l-dopa which is used directly to treat Parkinson's disease. Several studies have also indicated that L-Tyrosine benefits people with Alzheimer’s disease, schizophrenia, and dementia. Tyrosine and tryptophan have been used successfully in the treatment of cocaine abuse. In another study, it was combined with the antidepressant Imipramine to treat chronic cocaine abuse where it was found out that the action of the two blocked the cocaine high and prevented the severe depression that accompanies withdrawal.

Aside from its obvious brain functions because of its link to dopamine as well as norepinephrine, Tyrosine is also helpful in suppressing the appetite and reducing body fat, producing the skin and hair pigment (melanin), and aiding in the proper functioning of the thyroid as well as the pituitary and adrenal gland. It is beneficial for stress reduction and may be beneficial in narcolepsy, fatigue, anxiety, depression, allergies, headaches as well as drug withdrawal. In one study with soldiers as subjects, tyrosine proved effective in alleviating stress and keeping them more alert. Other possible benefits of tyrosine include helping to calm the body, increasing energy, and enhancing libido. It is also converted into the skin pigment melanin that shields the skin from the harmful effects of UV rays.

L-tyrosine, through its effect on neurotransmitters, is used in mood enhancement, appetite suppression, and growth hormone stimulation. In addition, tyrosine also has an antioxidant effect, which may prevent cancer development, coronary heart disease, and slow down the signs of aging. Tyrosine appears to prevent the decline in various aspects of performance and mood associated with many kinds of acute stress by acting as an adaptogen, helping the body cope with the effects of physical or psychological stress, and may prove helpful in enhancing performance in situations where performance is compromised. Tyrosine is involved in the synthesis of enkephalins, compounds that have pain-relieving effects. When taken properly, l-tyrosine can help improve a sluggish thyroid and assist a person who is on diet in losing excess, unwanted pounds. At present, it is often used as a dietary supplement for relieving stress, depression and in promoting general well being. It is also being popularly used as a supplement for body building, weight loss, and promoting skin health.

How pure is your N-Acetyl L-Tyrosine (NALT)?

This pharmaceutical grade amino acid N-Acetyl L-Tyrosine is assayed by the manufacturer to be 99.3% product. You will receive a sealed and labeled heavy duty 4 mil polyethylene bag containing this white powder product. Even if tyrosine is non-essential and that tyrosine is largely available through tyrosine foods, some people have increased needs of tyrosine due to one or several factors, while other suffer from tyrosine deficiency. For example, people going through depression reportedly have low tyrosine levels, as with those who suffer from phenylketonuria. If you have extremely low levels of tyrosine, you will suffer from a variety of conditions, such as muscle weakness, muscle loss, mood disorders, low protein level and liver damage. If you are one of those who have increased tyrosine level need or suffer from deficiency of the amino acid, taking in tyrosine through natural tyrosine foods is not enough so you would need actual tyrosine supplementation.

What is the daily suggested dose of N-Acetyl L-Tyrosine (NALT)?

Recommended dosing for N-Acetyl L-Tyrosine vary between as little as 150 milligrams per day to as much as 700 milligrams per day, depending upon individual needs. One eighth teaspoon will supply approximately 412 mg of this NALT powder Some people find that taking two doses per day of N-Acetyl L-Tyrosine is optimally effective for them, whereas some people find that they can take N-Acetyl L-Tyrosine only once per day with satisfactory results. You can see the full bulk density/volumetric conversion chart for NALT here. Some health practice professionals consider doses larger than 400 milligrams per day to be unnecessarily large for most people, while there are some who find doses as little as 75 milligrams taken twice per day to be effective.

You should consider that L-Tyrosine supplementation will take between 2 and 4 weeks at a given dose to give you a complete understanding of the dosage level you are taking. If you experience difficulty sleeping when taking N-Acetyl L-Tyrosine, reduce your dose. If you need to increase it, do it gradually to prevent and undesired effect. If you find you are being over stimulated by your L-Tyrosine dose you should cut your dose down and reevaluate your results after about two weeks at your new dose. Likewise, if you find you could use greater stimulation and mood enhancement you might try increasing your dose accordingly. L-tyrosine supplements should be taken before meals, preferably 30 minutes before, and divided into two or three doses daily.

Potential side effects of N-Acetyl L-Tyrosine (NALT)

High dosages of N acetyl tyrosine can cause insomnia and increased heart rate. We suggest not taking n acetyl tyrosine supplements the same day as other pills that increase metabolism or heart rate or cause alertness and have a stimulating effect.

Effect of high-dose tyrosine supplementation on brain function in adults with phenylketonuria
The objective of this study was to characterize abnormalities of brain function in patients with phenylketonuria (PKU) who had relaxed or stopped the dietary regimen and to test whether oral high-dose tyrosine (Tyr) supplementation has a beneficial effect. Overall data suggests high-dose Tyr supplementation cannot be recommended as an “alternative” treatment for patients with PKU after relaxation or termination of strict dietary adherence.

In search of the action of anti-depressants, 5HTP, tyrosine mixtures in depression
For a long time antidepressants have been considered to act via enhancement of central monoaminergic activity (due to reuptake or MAO inhibition). An alternative hypothesis holds that their action is based on down-regulation of monoaminergic activity (due to decrease in density or sensitivity of certain receptor populations). In this paper the likelihood of both hypotheses is discussed and the conclusion reached that the first one is the most plausible. The following arguments are discussed: (1) the 5-HT precursor 5-HTP, which is transformed to 5-HT in the brain, has antidepressant properties; (2) there are indications that the same holds true for tyrosine, a catecholamine precursor transformed in the brain to DA and NA; and (3) evidence was found that the effects of 5-HTP in depression are potentiated by tyrosine. Since activation rather than suppression of monoaminergic activity seems to be linked to antidepressant activity, it seems likely that the signs of decreased monoamine metabolism that have been demonstrated in certain types of depression are the expression of a primary metabolic deficit rather than a phenomenon secondary to receptor hypersensitivity. Further clinical studies of 5-HT/CA precursor combinations in depression are justified.
