What is L-Tyrosine?
L-Tyrosine is an amino acid, one of the building blocks of protein. The body makes it from another amino acid called 'phenylalanine'. L-Tyrosine plays an important role in making key messengers and hormones the body needs, including dopamine, adrenaline and thyroid hormones.
What does the research say about L-Tyrosine?
Researchers have looked at L-Tyrosine and the effects of stress on mental performance. Studies have measured working memory, cognitive flexibility and alertness, especially under a heavy workload or a lack of sleep.

Why it's in Stay Calm®
L-Tyrosine is a non-essential amino acid and a precursor for neurotransmitters, including dopamine, adrenaline and noradrenaline. These neurotransmitters play a role in the body’s stress response, mood regulation, and cognitive function. By providing additional tyrosine and replenishing neurotransmitter levels, the body and brain are better able to function optimally during periods of acute or chronic stress, especially for functions such as mental performance, focus, and resilience.
Neurotransmitter synthesis: L-Tyrosine supports the production of dopamine, noradrenaline, and adrenaline, which are often depleted during stress.
HPA axis: L-Tyrosine supports catecholamine production, which modulates the hypothalamic-pituitary-adrenal (HPA) axis and reduces the physiological impact of stress.1
Cognitive preservation under stress: L-Tyrosine prevents stress-induced declines in working memory, attention, and decision-making by maintaining neurotransmitter levels in the brain. It is particularly effective during sleep deprivation or extreme physical or mental demands.2
Thyroid support: L-Tyrosine is also a precursor for thyroid hormones (T3 and T4), which can be negatively impacted by chronic stress, influencing metabolism and energy.3
