NutraBio L-Tyrosine
L-Tyrosine is an amino acid which may support brain function. Tyrosine may be converted by neurons in the brain into the neurotransmitters dopamine and norepinephrine (noradrenaline), hormones which may be depleted by stress, excessive work and certain drugs. By replenishing norepinephrine in the brain, mental energy levels are enhanced and a feeling of contentment often occurs.
L-Tyrosine may boost certain neurotransmitters in the brain and has been used to potentially support stress reduction. L-Tyrosine is converted in the body into other key biologic compounds, including CoQ10, thyroid hormones and melanin.
Tyrosine can also enhance athletic performance. L-Tyrosine is an important component of protein and helps form the bioactive factors vital to cellular growth and maintenance. Tyrosine supplementation has the potential to increase athletic performance in a few ways. One of the mechanisms possibly contributing to fatigue during exercise is an increase in central serotonin levels and an increase in the ratio of serotonin to dopamine. Tyrosine may help decrease this ratio and compete with tryptophan (the amino acid precursor to serotonin) at the blood-brain barrier. Increased dopaminergic activity may decrease the perception of fatigue. Also, during highly stressful conditions, catecholamine levels can become depleted, and tyrosine may be particularly useful under these conditions.
