L-Tyrosine powder

What is L-Tyrosine?

L-tyrosine is one of the 20 nonessential amino acids used by cells to synthesize proteins.

It is used by strength athletes like bodybuilders and weightlifters because of its reputation for offsetting muscle stress and fatigue during intense training.

Tyrosine is considered a nonessential amino acid since it can be made in the body from phenylalanine, another amino acid.

Tyrosine is a precursor of the thyroid hormones threonine and thyroxine as well as the adrenal and growth hormones epinephrine, dopamine and norepinephrine.

It is also used in the body to create melanin, pigmentation in the skin that helps shield the body from the harmful ultraviolet rays of the sun.

Tyrosine deficiency may cause a variety of conditions, including muscle loss, weakness, low protein levels, mood disorders and liver damage. Most people suffering from phenylketonuria, the inability to metabolize phenylalanine, are deficient in tyrosine.

Dietary sources of tyrosine include soy products, chicken, turkey, fish, peanuts, almonds, avocados, bananas, milk, cheese, yogurt, cottage cheese, lima beans, pumpkin seeds and sesame seeds.

Health Benefits of L-Tyrosine

L-tyrosine is a precursor of dopamine, a neurotransmitter associated with movement, attention, learning and the brain’s pleasure and reward system.

Tyrosine supports mental alertness and increased feelings of well-being and offsets physical and mental fatigue.

Tyrosine has an antioxidant effect, helping to protect cell membranes from the damage caused by free radical molecules in the body.

Potential Side Effects of L-Tyrosine

L-Tyrosine is generally safe at suggested serving sizes. Larger amounts can cause restlessness, anxiety, euphoria and insomnia. Instances of overstimulation, heart palpitations and arrhythmia have also been reported.

Those with high blood pressure or who suffer from migraines should not use tyrosine supplements. Those taking monoamine oxidase (MAO) (Wikipedia) inhibitors should not use tyrosine or phenylalanine supplements. Tyrosine should not be taken at the same time as levodopa, a medication used to treat Parkinson's disease. People with liver or kidney disease should not take this or any other amino acid supplement without first consulting their physician. This product is not recommended for women who are pregnant or nursing.

The body needs a balanced supply of all the amino acids in order to effectively create and utilize proteins. Those supplementing any of the amino acids should have a balanced intake of the others.

Suggested Use of L-Tyrosine

As a dietary supplement, take 1 capsule up to three times daily between meals (or as directed by physician.) Individual needs vary. L-tyrosine supplements should be taken 30 minutes before meals.
