Lamberts L-Phenylalanine 500mg Description

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.

Amino acids are classified as either essential or non-essential. Essential amino acids cannot be synthesised in the body and must be obtained from the diet, whereas non-essential amino acids, whilst still essential for health, can be synthesised in the body and are therefore not classified as 'essential'.

Phenylalanine is an essential amino acid and is the precursor for the amino acid tyrosine. Like tyrosine, it is the precursor for the neurotransmitters called catecholamines (adrenaline, noradrenaline and dopamine).
