Usage

General Description

H-TYR-PHE-OH, also known as N-acetyl-L-tyrosine-L-phenylalanine, is a combination of two amino acids- tyrosine and phenylalanine, with an added acetyl group. It is commonly used as a dietary supplement and is thought to help improve focus, attention, and stress management. Tyrosine is a precursor to neurotransmitters like dopamine and norepinephrine, which are involved in regulating mood and mental alertness, while phenylalanine is involved in the synthesis of tyrosine. The acetyl group allows for better absorption and utilization in the body, potentially enhancing its cognitive and neurological effects. H-TYR-PHE-OH is also used in the pharmaceutical industry for the synthesis of various drugs and is commonly included in pre-workout and energy supplements to support mental clarity and cognitive function during exercise.
