L-Phenylalanine

L-Phenylalanine is an essential amino acid that plays a key role in our metabolism by synthesizing proteins. As an essential component which our bodies cannot produce on their own, it is important to have an adequate supply through diet and supplements. Amino acids are also important as our bodies use them to generate antibodies, hormones, enzymes and neurotransmitters, supporting many bodily functions. L-Phenylalanine plays a key role in the creation of happy hormones such as norepinephrine and dopamine which is why this amino acid has been studied as a possible treatment for depression. 

There has been extensive research of how L-Phenylalanine can support the treatment of certain medical conditions such as the treatment of skin conditions. Some evidence suggests that L-Phenylalanine could improve symptoms in people with vitiligo, a condition which causes loss of skin pigmentation.
