Tyrosine – Amino Acid That Regulates Your Mood And Hair Color

Tyrosine is a nonessential amino acid that is used by cells to synthesize proteins and make brain chemicals and thyroid hormones. Phenylketonuria patients lack enzyme that changes phenylalanine (Phe) into tyrosine, which can increase the Phe levels in their blood.

Tyrosine is used in protein supplements for people who suffer from PKU. It can be found in lots of high-protein food such as turkey, fish, chicken, almonds, milk, yogurt, bananas, avocados, peanuts, cheese, pumpkin seeds, soy products, sesame seeds and bananas.

Some studies indicate that tyrosine can influence mood, regulate adrenal glands and produce melanin which is responsable for skin and hair color.
