Phenylalanine

Phenylalanine is an amino acid that is used by our bodies to create molecules and proteins. There are two types of phenylalanine – L-phenylalanine and D-phenylalanine, and they each have their own unique molecular composition. L-phenylalanine is used to produce proteins in the body and can be found in many foods that are both animal and plant-based. D-phenylalanine is used in medical treatments. Phenylalanine is important for ensuring the health of the nervous system and the way the brain sends messages around the body. It can also be used to treat disorders of the skin, administer pain relief and treat depression.
