Kaizen L-Tyrosine Kaizen
L-Tyrosine

Tyrosine was originally classified as a nonessential amino acid, but now is considered Semi-essential, by most nutritionists. This amino acid is a precursor to an important brain neurotransmitter involved in mood, mental function and sex drive. Severe or prolonged stress can deplete the substance (neurotransmitter) norepinephrine in the brain. You may experience this lack of norepinephrine as fatigue, feelings of helplessness, and depression. It also causes impairment of immune function and may contribute to other health problems. Many depressed persons do not have enough norepinephrine in their nerve cells. Norepinephrine also has an appetite suppressant. Tyrosine is also used by the thyroid gland for the production of Thyroxine, a vital hormone involved in regulating growth, metabolism, skin health and mental state. Clinical studies indicate that Tyrosine can be helpful in reducing the irritation, fatigue and depression of PMS sufferers.
