L-Tyrosine 90's - 90 capsules by Pure Encapsulations

Neurotransmitter precursor for mood and memory *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. Tyrosine is also a key component in the synthesis of thyroid hormones. l-Tyrosine supports production of catecholamine neurotransmitters, enhancing mood and cognitive function especially under situations involving stress or when dopamine, epinephrine or norepinephrine levels require additional support.* Ingredients:l-Tyrosine Supplemental Facts Amount Per Serving each vegetarian capsule contains: l-tyrosine (free-form) 500 mg. other ingredients: vegetarian capsule (cellulose, water) 1-4 capsules daily, in divided doses, between meals.
