Pure Encapsulations® DL-Phenylalanine – Combination of D- and L-phenylalanine of tested quality

Additional product information

Pure Encapsulations® DL-Phenylalanine combines the two forms D-phenylalanine and L-phenylalanine in a balanced ratio.

L-phenylalanine is one of the essential amino acids and must be consumed regularly through the diet. It is an important building block of the body's own proteins and serves as a precursor for the formation of the amino acid tyrosine.

Tyrosine, in turn, is needed by the body for the production of various messenger substances and thyroid hormones.

The vegan formula is suitable for the targeted supplementation of amino acid intake.

Properties and benefits

• DL-Phenylalanine: Combination of D- and L-phenylalanine.

• Essential amino acid: L-phenylalanine must be obtained through the diet.

• Protein metabolism: L-phenylalanine is a building block of the body's own proteins.

• Tyrosine formation: L-phenylalanine can be converted into tyrosine in the body.

• Neurotransmitter metabolism: Tyrosine is a precursor of dopamine, noradrenaline and adrenaline.

• Thyroid hormones: Tyrosine serves as a starting material for their endogenous formation.

• Tested quality: Manufactured according to high international quality standards.

• Vegan: Free from animal ingredients.

• Gluten-free, lactose-free and soy-free.

Phenylalanine – An essential amino acid

Phenylalanine is one of the nine essential amino acids for humans.

The body cannot produce essential amino acids in sufficient quantities itself. They must therefore be consumed regularly through the diet.

Phenylalanine occurs naturally in protein-rich foods such as meat, fish, eggs, dairy products, legumes and nuts.

Phenylalanine as a precursor of tyrosine

In the liver, L-phenylalanine can be converted into L-tyrosine with the help of the enzyme phenylalanine hydroxylase.

Tyrosine is required for various metabolic processes and is a starting material for the body's own formation of important compounds.

These include:

• Dopamine

• Noradrenaline

• Adrenaline

• Thyroid hormones

The formation of these substances is controlled by various endogenous regulatory mechanisms.

L-Phenylalanine and D-Phenylalanine – What is the difference?

Phenylalanine can occur in two mirror-image forms:

• L-Phenylalanine: The natural, protein-forming form that occurs in foods and is required for human protein metabolism.

• D-Phenylalanine: The mirror-image form, which is not among the essential protein-forming amino acids and is being studied with regard to its biological properties.

DL-Phenylalanine contains both forms as a mixture.

The physiological functions of L-phenylalanine cannot be transferred without restriction to D-phenylalanine.

Phenylalanine in the diet

Phenylalanine is a component of numerous plant and animal proteins.

Even with a vegetarian and vegan diet, requirements can be met through a balanced selection of protein-rich foods.

If amino acid intake is insufficient, targeted supplementation may be considered.

DL-Phenylalanine in tested quality

Pure Encapsulations® DL-Phenylalanine combines D- and L-phenylalanine in a convenient capsule form.

Manufacturing is carried out according to controlled quality standards.

The formula is vegan and free from gluten, lactose and soy.

Important notes

Food supplements are not a substitute for a balanced, varied diet and a healthy lifestyle.

Do not exceed the recommended daily intake. Keep out of the reach of small children and store in a cool, dry place.

Important for phenylketonuria (PKU): The product contains phenylalanine and is not suitable for persons with phenylketonuria unless there is an express medical instruction.

If taking MAO inhibitors, levodopa or other medicines that affect catecholamine metabolism, use should be clarified with a doctor in advance.

In cases of high blood pressure, cardiovascular disease or existing psychiatric disorders, prior medical advice is advisable.

During pregnancy and breastfeeding, intake is not recommended without medical advice due to insufficient safety data.
