l-tyrosine

L-Tyrosine is a naturally occurring amino acid that acts as a nootropic that improves brain function.

L-Tyrosine can also be used to support weight loss.

As a Nootropic:

L-Tyrosine is used by the body to manufacture a number of hormones and neurotransmitters including dopamine, norepinephrine, epinephrine, and thyroxine.

Increasing these hormone and neurotransmitter levels leads to increased wakefulness, as well as improved mood, focus and attention.

Additionally, boosting these hormone and neurotransmitter levels protects your mental state in periods of stress.

To elaborate, when you experience stress, your brain releases norepinephrine to stimulate your central nervous system (CNS), and to increase your energy and mental power.

Unfortunately, this depletes the norepinephrine stores, which produces fatigue, and in the presence of stress can produce anxiety.

To combat this, L-Tyrosine increases the rate of noradrenaline synthesis so that you are less susceptible to stress, and so you do not experience an energy crash.

Studies show that L-Tyrosine increases both memory and mental performance under psychological stress and in distracting environments.

L-tyrosine functions synergistically with L-Carnitine, Caffeine, and Alpha-GPC to improve brain performance.

For Weight Loss:

L-Tyrosine also acts as an appetite suppressant. Higher levels of L-Tyrosine in your body tell your brain that you are full, which in turn decreases appetite.

Moreover, L-Tyrosine stimulates the neurotransmitter norepinephrine. Again, higher norepinephrine levels decrease appetite.

Also, the combination of L-Tyrosine and caffeine will increase fat burning.

Finally, L-Tyrosine works synergistically with L-Carnitine to increase fat oxidation.
