Provides l-tyrosine, an amino acid that the brain, adrenals, thyroid and other organs use to make neurotransmitters that are crucial to emotional balance and adaptability, especially when under mental strain.
Healthy Stress Response
Tyrosine supports the brain, adrenals and thyroid, especially when coping with stress or intense mental strain.
Promotes Healthy Emotional Balance
Tyrosine is a precursor (starting molecule) for the catecholamine neurotransmitters dopamine (DA) and norepinephrine (NE). The brain needs DA especially for working memory ("multitasking"), and NE especially for cognitive adaptability. NE and DA operate in synchrony with the brain's other neurotransmitters to promote healthy mood, behavior and mental focus.
Supports Mental Focus Under Stressful Challenge
Stress, or sometimes just intense mental effort, intensifies brain activity and depletes supplies of DA and NE. The brain has special transport enzymes that import l-tyrosine across the blood-brain barrier, as needed to replete DA and NE. In a double-blind clinical trial, a 2-gram dose of tyrosine helped undergrad students perform better at multitasking, to "make the right choices" under mental challenge.
Supports Healthy Adrenal Gland Function
Emotional intensity or stress stimulates the adrenals to release NE, and E (epinephrine, adrenaline) that they make from NE. This NE helps the brain cope with the challenge. The adrenals also rely on DA for their normal stress response. Healthy adrenal function requires ample l-tyrosine to sustain their production of DA, NE and E.
Supports Healthy Thyroid Gland Function
The thyroid makes the hormone thyroxine (tetraiodothyronine, T4). This hormone helps regulate the body's energy metabolism, but when under stress may make less T4. The brain needs l-tyrosine in order to regulate the thyroid to ensure T4 production.

Tyrosine (l-tyrosine) is an amino acid that is required for the production of the neurotransmitters dopamine, epinephrine, and norepinephrine. The thyroid gland needs tyrosine to make the hormone thyroxine, and the skin needs it to make melanin. Having sufficient quantities of tyrosine in the brain promotes mental clarity in dealing with stress.
