Is N-Acetyl L-Tyrosine?
L-Tyrosine, or NALT for short, is considered to be a modified formulation of
the non-essential amino acid, L-Tyrosine.
is an amino acid that the body is capable of producing internally, but supplementation
is often necessary to optimize cognitive function.
is modified from normal Tyrosine because it contains the addition of acetic
acid. This is believed to help increase the compound’s bioavailability so that
it is better absorbed directly into the bloodstream, however research on this
acid also has some important benefits in its own right for brain health. For
these reasons, N-Acetyl L-Tyrosine is a popular form of supplemental
acids are vital to the body for a number of reasons. They help to make
proteins, build up new cells, aid in the recovery and rebuilding of muscles,
etc. But one of the main things which makes Tyrosine special is that it also is
a precursor to the catecholamines.
are a group of monoamine compounds that act as hormones and neurotransmitters
in the body. The main catecholamines are Dopamine, Epinephrine (Adrenaline),
and Norepinephrine (Noradrenaline). These powerful neurotransmitters are
associated with mood, attention, focus, and alertness.
primary benefits of N-acetyl-L-tyrosine revolve around dopamine and adrenaline
metabolism. Studies suggest that NALT can increase mood in military personnel
exposed to stressors like cold and altitude . One can reasonably assume this
mood boost is via dopamine improvements from taking the L-tyrosine.
benefit of NALT is for memory protection against stress. One study showed that
L-tyrosine could increase adrenaline concentrations and reverse memory loss
caused by stress. In fact, one of the primary benefits of N-acetyl-L-tyrosine
is related to handling stress as much of the literature suggests.
stressful conditions (acute stress rather than chronic) general cognitive
enhancement suffers greatly. Most of the studies with L-tyrosine (and relate to
NALT) are on military personnel tested in stressful situations. One study on
cadets showed cognitive preservation during a week of difficult training .
Another measured how L-tyrosine improved mental performance during extreme
sleep deprivation as well.
benefit of using NALT is that the substance has increased solubility. In fact,
it is 20 times more water soluble than L-tyrosine alone and anecdotal effects
suggest improved mood and focus even though there isn’t much evidence to
support those claims.
