Tyrosine Ethyl Ester Powder - 150 Grams

Benefits:

Pharmaceutical grade esterized L-Tyrosine for maximum bioavailability. 99.98% pure with no fillers or additives. HPLC verified.

L-Tyrosine is an essential amino acid which supports brain function. It can be converted by neurons in the brain into the neurotransmitters 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 has been used to support stress reduction and depression. L-Tyrosine is converted in the body into other key biologic compounds, including L-dopa, 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.

NutraBio.com L-Tyrosine Ethyl Ester is manufactured from pure free form crystalline amino acid. It is NOT derived from milk. The B vitamins pyridoxine (B-6) and folic acid can assist in the conversion process.

The benefits of L-Tyrosine Ethyl Ester: Amino Acid Esters are amino acids with an ester molecule attached. Esters are organic compounds that are formed by esterification, which is the reaction of carboxylic acid and alcohols. Esters are organic compounds that help shuttle the amino acid across lipid membranes of the gut and directly into the bloodstream for direct transport to your cells. This prevents the amino acid from being destroyed in the gut and drives more of the free form amino acid directly into muscle tissue where it can be more efficiently used for its intended purpose.

Free form amino acids have inherent limitations such as limited absorption through the intestine. Whereas amino acid esters can pass through the intestine largely intact, regular free form aminos can be significantly degraded in the intestine, leaving only trace amounts of the ingested dose active. Because of the rapid breakdown of some amino acids in the intestine, its beneficial effects can be limited. Ethyl ester amino acids are thought to have a much better absorption rate and a longer half-life in the body than regular free from amino acids because it is slightly more lipophilic.

Amino acid ethyl esters are technically amino acids derivatives. Their ergogenic effects are similar to those of their base free form amino acids, but the presence of an ester will make the ergogenic effects of more pronounced. The presence of the ester not only enhances the function of amino acid and overcomes its inherent limitations, but the presence of an ester and increased absorption also reduce the need for large doses, which may put less stress on the body.

Suggested Use: As a dietary supplement, take 1 serving daily on an empty stomach immediately after arising in the morning, preferably with juice as a carbohydrate source, or as directed by your physician.

WARNING: NOT INTENDED FOR USE BY PERSONS UNDER THE AGE OF 18. KEEP OUT OF THE REACH OF CHILDREN.

Not for use by persons with a history of malignant melanoma or if bipolar, pregnant, suspect pregnancy, or lactating. Tyrosine should not be taken by those with conditions associated with increased dopamine levels such as mania and schizophrenia. This supplement may increase sensitivity to the effects of CNS stimulants. Caution is advised when taking tyrosine along with stimulants and dosages should be lowered accordingly.
