Phenylalanine? Phenylanine is a common misspelling of phenylalanine.
Phenylalanine is an amino acid that is important for building proteins. It is a naturally occurring substance; however, the body does not make its own (it must be obtained from dietary sources or supplements). Phenylalanine supplements are supposedly useful for treating conditions such as depression, arthritis, and ADHD. It may also be effective in the treatment of vitiligo.
