Tyrosine is an amino acid that is naturally produced in the body and you can get it in cheese, dairy, chicken and other high-protein foods. In the nootropic world, it is used for memory, focus, improved mood, and concentration.

Because of its wide mode of operation, there are some interesting ways that scientists are studying how it can be used in human health and wellness:

ADHD (Attention-deficit / hyperactivity disorder)

Combining L-Tyrosine with ALCAR (Acetyl-L-Carnitine) can help with ADHD/ADD. ALCAR can easily enter the brain and increase acetylcholine levels, which might also improve serotonin levels. Tyrosine helps the brain produce dopamine, which can help reduce ADHD/ADD symptoms.

Neurologica® ACTIVATE is made with this combination.

Activate ADHD


A study done in the UK in 20191 took 46 healthy people and tested their reactions to fear. They found that when people took L-tyrosine, it removed the effects of fear on their bodies, without changing their mood. This is good to know because it shows how important dopamine and adrenaline are in managing fear responses.

Hypertension & High Blood Pressure

A study2 published in the Journal of Clinical Investigation investigated the effect of L-tyrosine on the regulation of blood pressure in humans. The study found that L-tyrosine reduced blood pressure and improved the function of the thin layer of cells that line our blood vessels.

Way back in 1999, while most of the world was worried about Y2K, researchers in USA investigated the effects of L-tyrosine multitasking abilities in healthy adults3. The results showed that those who took L-tyrosine performed better on tasks that required cognitive flexibility and multitasking, compared to those who took the placebo. The researchers concluded that L-tyrosine may enhance cognitive performance in situations where high demands are placed on the brain’s executive functions, such as multitasking.

Endurance exercise

A study4 published in the European Journal of Applied Physiology examined the effect of L-tyrosine supplementation on endurance exercise performance. The study found that L-tyrosine improved endurance exercise performance and reduced the feeling of tiredness.
Nootropics for Motivation

L-Tyrosine has been included in Neurologica® SWITCH and ACTIVATE. In SWITCH, it is stacked with the South African herb, Sceletium tortuosum, to help improve mood by helping to activate the dopamine production the body.

In ACTIVATE, L-Tyrosine is blended with ALCAR and Co-Enzyme Q10 to help get the motivation and productivity going at a stronger pace.
