Phenylalanine is a basic amino acid to most of nature. In plants it is the first phenolic step in the creation of cinnamic acid, caffeic acid, coumarin and coniferyl alcohol. In humans and other higher life forms, phenylalanine is an important building block for a wide number of functions. Most important is its function in building the neurotransmitters of the dopamine-epinephrine pathway. Phenylalanine is also important in the building of several proteins in the body. Phenylalanine greatly affects mood and behaviors. Its best benefits are seen with headaches and depression but it has also helped with sleep problems and blurring vision.
