Each L-Tyrosine capsule contains 400 mg of L-tyrosine, a conditionally essential amino acid the body can convert to the neurotransmitters dopamine, epinephrine, and norepinephrine. These neurotransmitters are found to increase mental alertness and focus and also preserve normal memory under stressful conditions. N-acetyl-L-cysteine is present to support glutathione production, antioxidant activity, and neuronal protection.
Stress conditions, such as a cold environment, psychological stress, sleep deprivation, and strenuous, prolonged athletic activity, appear to reduce the body’s ability to convert phenylalanine to tyrosine. This underproduction may manifest itself as poor memory and performance. Tyrosine, as a precursor for catecholamine synthesis, presumably augments brain catecholamine levels and improves working memory under stress. Tyrosine also supports adrenal and pituitary function and may increase thyroid hormone. Additionally, it is necessary for the production of the skin pigment, melanin. Oral contraceptives may cause a decline in tyrosine plasma levels, possibly because estrogen can increase glucocorticoid levels. This, in turn, elevates levels of tyrosine aminotransferase, which degrades tyrosine in the liver.
Directions: Take one to three capsules one to three times per day, or as directed by your healthcare practitioner.
