DL Phenylalanine

DL-Phenylalanine is a combination of the well-tolerated essential amino acids, d-phenylalanine and l-phenylalanine. Together, these two essential amino acids help promote mental functioning such as memory and learning, support positive outlook and emotional well-being. This supplement may promote levels of certain endorphins, helping to calm stressed muscles and joints.

In the body, l-phenylalanine converts into tyrosine, which may support emotional well-being, memory and learning, while d-phenylalanine may promote the levels of certain endorphins, thereby calming stressed muscles and joints.
