l-Tyrosine – L-tyrosine by Pure Encapsulations is an amino acid which is a precursor for many neurotransmitters including dopamine, epinephrine and norepinephrine, as well as thyroid hormones that help with mood and cognitive function. This amino acid, although made readily by the body, is supplemented by those looking for a boost in mood and cognitive support. This ingredient has been used for many years safely and effectively for helping to control anxiety and stress.

Uses For l-Tyrosine

Cognitive Health: In the body, phenylalanine is converted to tyrosine. The amino acid tyrosine is a precursor of catecholamine neurotransmitters, including l-dopa, dopamine, epinephrine, and norepinephrine. These neurotransmitters are responsible for supporting emotional well-being and mental function. l-Tyrosine plays a role in promoting healthy neurotransmitter function in response to environmental and emotional stress. Research has indicated its potential to promote cognitive function and memory under stressful conditions. In one study, l-tyrosine enhanced mood and sleep in subjects with low dopamine levels.*

Thyroid:

Tyrosine is a key component in the synthesis of the thyroid hormone thyroxine.*

What Is The Source?

l-Tyrosine is extracted from protein and extensively processed and purified in a semi-synthetic process.
