L-TYROSINE POWDER - FREE FORM AMINO ACID - 100 Grams

L-Tyrosine is an essential amino acid which can be converted by neurons in the brain to dopamine and norepinephrine (noradrenaline), hormones which are 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 boosts certain neurotransmitters in the brain and also converts into a thyroid hormone. L-tyrosine has been used to support stress reduction and depression.

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.

NutraBio.com L-Tyrosine is pure free form crystalline amino acid from microbiological fermentation. It is NOT derived from milk.
