TYROSINE
This amino acid is a precursor of adrenaline, norepinephrine and dopamine (regulates mood and stimulates metabolism and the CNS). A lack of tyrosine can result in depression, low blood pressure, low body temperature and restless leg syndrome. L-tyrosine has been used in cases of stress reduction as it aids in adrenal gland function, anxiety disorders, low sex drive, allergies, headaches and Parkinson’s. It can be helpful against chronic fatigue and narcolepsy. If you need help achieving a healthy body weight, tyrosine suppresses the appetite, helps to reduce body fat, and is important to overall metabolism. Tyrosine helps form thyroid hormones; low levels have been associated with hypothyroidism.

FACTS ABOUT AMINO ACIDS
Without adequate amounts of phenylalanine, the body can’t manufacture it’s own supply of tyrosine; without adequate amounts of tyrosine, the body cannot metabolize phenylalanine. A shortage of either of these amino acids could leave you vulnerable to a host of mental disorders. Your body manufactures tyrosine from phenylalanine. You can get phenylalanine from almonds, avocados, bananas, dairy foods, beans, and seeds. (see PKU under PHENYLALANINE - a genetic condition that makes it impossible to convert phenylalanine into tyrosine).
