Amino Acids



L-tyrosine is a non-essential amino acid that the body can synthesize from phenylalanine. It is used by the body to produce neurotransmitters, which are chemicals that send signals throughout the nervous system. In addition, it has action on disorders such as depression, anxiety, and stress-related sleep problems. Some studies suggest that L-tyrosine can help improve mental and physical performance during stressful situations, such as exams, tests, or presentations. This substance is also a precursor to melanin, the pigment that gives skin and hair their color.
