NALT | N-Acetyl-L-Tyrosine

No reviews

NALT is an “upgraded” form of tyrosine with much better bioavailability. This amino acid helps to improve the levels of self-perceived energy and motivation. It has a scientifically proven, positive effect on cognitive functions – it helps to maintain a high level of focus, even in demanding situations. Furthermore, there are suggestions that NALT might be a support for a good mood and physical performance.

NALT | N-Acetyl-L-Tyrosine

Properties: NALT or N-acetyl-L-tyrosine is a synthetic derivative of naturally occurring amino acid tyrosine. NALT differs from tyrosine mainly due to its much higher bioavailability in the digestive tract. This is essential, because L-tyrosine has biologically important roles and its optimal level is crucial for proper functioning of the organism.

L-tyrosine is a dopamine precursor and therefore it increases the activity of this neurotransmitter in the brain. This leads to enhanced feelings of vitality and motivation. Dopamine is also important when we want to maintain concentration and focus particularly on the task at hand. Thus, by supplementing its direct precursor, we can significantly improve our intellectual abilities. 

NALT has also a positive effect on physical performance because it stimulates the secretion of adrenaline and noradrenaline – two hormones responsible for mobilizing the entire organism. It is also important to keep in mind that the production of dopamine is related to the activity of the so-called “reward system”. Therefore, providing the organism the substrate crucial for its production leads to an increased feeling of satisfaction that arises from getting things done.

Occurrence: N-acetyl-L-tyrosine does not occur naturally. Instead, it is synthetically obtained in the laboratories from the combination of the amino acid L-tyrosine and acetic acid.

Biochemistry: N-acetyl-L-tyrosine is a derivative of L-tyrosine, an amino acid that naturally occurs in the human organism. There is, however, a crucial difference between these two substances: NALT has 20 times greater solubility in water and better bioavailability. In other words, its absorption in the organism is enhanced and therefore, it is more accessible to the cells, where it can be transformed to L-tyrosine. This important amino acid plays a role in cellular information transmission. Moreover, in the central nervous system it serves as a substrate for the production of neurotransmitters from the catecholamines family.

Fun fact: N-acetyl-L-tyrosine supports the therapy of a disease known as phenylketonuria, in which the organism loses the ability to metabolize phenylalanine. Therefore, the excess of this compound is stored in the blood and other tissues. If untreated, it can lead to neurological disorders and brain damage.

How does NALT | N-Acetyl-L-Tyrosine work?

Increases energy level: N-acetyl-L-tyrosine shows the ability to modulate the activity of catecholamines – key excitatory neurotransmitters that have an important role in terms of motivation. NALT, as a form of tyrosine, is a substrate in the production of dopamine, however, it is also involved in the synthesis of epinephrine and norepinephrine. In studies with animal models, it has been proven that NALT supplementation might increase norepinephrine level in the brain. Since this form of tyrosine takes part in the processes that lead to the production of other catecholamines, it might help to maintain a high level of mental stamina, improving the functioning of the mind, even in stressful conditions.

Supports attention: The optimal level of dopamine is crucial for a high level of concentration. By upregulating the activity of this neurotransmitter, NALT improves the capacity of working memory. Moreover, it helps to focus attention and move its loci from one point to another. This way, NALT supplementation might be a valuable support for multitasking – the ability that is especially important when one has to perform different tasks at the same time. Besides that, research indicates that NALT might improve cognitive functions, particularly when they are impaired due to sleep deprivation. During attention tests, after 24 hours of no sleep, the participants who took NALT achieved better results than the placebo control group. It is estimated that this cognition-enhancing effect lasts up to 3 hours.

Supports physical performance: NALT is a derivative of L-tyrosine – an amino acid that has many important functions in the human body. As data suggests, it can influence cognitive performance but also participates in the synthesis of proteins and supports the development of cells. The results of scientific studies prove that NALT stimulates the production of neurotransmitters that energize the whole body – particularly dopamine, epinephrine and norepinephrine. When their activity within the nervous system is increased, they induce a high level of motivation and perceived energy which might be especially helpful during intense workout.

Improves general well-being: Dopamine is a neurotransmitter that has many different functions and affects key processes that occur in the human body. Even though this substance is mostly associated with energy and motivation, it is worth noting that balanced dopamine activity is also crucial for a positive attitude. When this compound is secreted, it might affect the so-called “reward-system” that is related to the feeling of pleasure. Research indicates that NALT supplementation improves the density of dopamine in the central nervous system which is beneficial for a general mood. It has also been shown that this amino acid can support stress resilience. Some of the measurable effects include the reduction of blood pressure that might be raised in response to a stressful event.
