Phenylalanine is an essential amino acid so it can not be synthesized by the body and must therefore be obtained from food. In the body phenylalanine is converted in to another amino acid, tyrosine, which in turn is used by the body to produce the neurotransmitters called catecholamines which include adrenaline, noradrenaline and dopamine. These three neurotransmitters are important in alertness, memory and muscle co-ordination.

Phenylalanine occurs in two forms; L-Phenylalanine which is a natural amino acid found in proteins and D-Phenylalanine which can be produced in a laboratory but is not needed by the body as a nutrient. Lamberts® Phenylalanine is the natural L-Phenylalanine and is presented in its free-form to help ensure optimal absorption.

Each capsule provides 500mg.

Please Note: People with a condition known as phenylketonuria (PKU), in which phenylalanine cannot be broken down, should not take phenylalanine supplements. Nor should phenylalanine supplements be taken in conjunction with prescription antidepressants, particularly monoamine oxidase (MAO) inhibitors.
